At first SRR was a regular construction site, but after a message for future generations was concreted in its foundation on May 27, 1960 in an official ceremony the government of Soviet Latvia proposed to turn SRR into a present from Latvian proletarians for the XXII Congress of the Communist Party of the Soviet Union in autumn 1961. The site became an object of high priority.

Construction of the reactor's pool was finished in spring 1961. Everything around the pool - walls, windows, floors – as well as the pool itself had to be cleaned otherwise all flecks of dust would become radioactive. It was done by the reactor's staff – they spent the whole summer cleaning. Cleaning was realized by joint works (also known as bees), which where mandatory and lasted full working day – 8 hours. The most famous of them took place on April 22, 1961. Maybe because it was Saturday 8 employees out of 37 did not attend the joint work at all, 7 later sneaked away.<ref>"Slepenais objekts Salaspilī", magazine "Ilustrētā Zinātne", No.9/2011</ref>

Blueprints and other documentation for SRR project were received from Kurchatov Nuclear Power Institute in Moscow, which offered to increase the reactor's nominal thermal power to 2 MW. This proposal was accepted by the presidium of the Academy of Sciences. In autumn 1960 graduates who had recently joined the reactor's staff pointed out that the standardized project is already out-of-date and persuaded the constructors to modify it. Graduates built a new device for preparation of 50 m³ of distilled water that was necessary for the pool. This device allowed to produce water much faster and was also cheaper than the original one. Another modification was the control room desk. In the original project only one person could work with it while in SRR two main workspaces and several extra workspaces were created.<ref>Book "Salaspils zinātniskā kodolreaktora 50 gadi", Publishing House "Zinātne", 2010</ref>

During the construction works the reactor was a secret object and was named “Object IRT”. Materials for the reactor were received from “post boxes”. For instance, “Post Box No.3” stood for fuel. The employees could not travel abroad, expect for business (conferences, etc.) and they were not allowed to meet foreigners alone, only in pairs. After such meetings both persons had to write down what they had talked about. Despite all secrecy around it, SRR was open for visitors after it was put into operation. It is presumed that more than 50,000 people, mostly pupils, have visited it between 1960s-1990s.

From September 1961 until June 1973, when SRR was closed for reconstruction, the reactor used EK-10 fuel with 10 % enrichment. After the reconstruction, from July 1975 until October 1979, IRT-2M fuel with 90 % enrichment was used. From October 1979 until July 1989 IRT-2M and IRT-3M (also with 90 % enrichment) were used. Starting from July 1989 until June 1998 only IRT-3M was used.

Reconstruction works were necessary due to several reasons. One of them was the problem with EK-10 fuel. Its rods started to curve in the active zone of the reactor and created danger of loss of hermetism. Another problem was corrosion in the pool's aluminium vessel. Aluminium  was replaced with stainless steel.<ref>Book "Salaspils zinātniskā kodolreaktora 50 gadi", Publishing House "Zinātne", 2010</ref> The Reactor's nominal thermal power was increased from 2 to 5 MW.

Physicists from SRR cooperated with physicists from different research reactors, other nuclear facilities and institutes of physics in the Soviet Union (for example, in Leningrad, Moscow, Belarus, Georgia), had partners abroad (for instance, in Germany, France, the Czech Republic) and carried out contract jobs. Also the Reactor  had trainees from Iraq, North Korea and Libya. Specialists from SRR have worked in Iraq and Libya.

After the collapse of the Soviet Union in 1991 Russia stopped to sell uranium to SRR. However, it did not affect the reactor. SRR usually used 4-5 bundles per year but the administration always ordered 7-8. These reserves where still used in 1998 when the reactor was shut down.

In 2013 the University of Latvia replaced the Latvian Environment, Geology and Meteorology Center, Ltd. as the operator of the facility, planning to develop a cyclotron center there. A cyclotron is a type of particle accelerator<ref>http://en.wikipedia.org/wiki/Cyclotron as of March 3, 2015</ref>  and has several usages. In medicine it can be used for cancer treatment and diagnostics of cardio-vascular diseases<ref>http://www.delfi.lv/news/national/politics/salaspils-kodolreaktora-likvidesanai-mekles-finansejumu-arpus-es-fondiem.d?id=45169436 as of March 3, 2015</ref>. University of Latvia also intended to export the developed medicinal products and conduce scientific researches. Export was considered because there are no cyclotron centers in neighbouring countries<ref>http://www.delfi.lv/news/national/politics/salaspils-kodolreaktoru-lu-cer-nodot-lidz-vasaras-vidum.d?id=43150852 as of March 3, 2015</ref>.

In October 2014 the University announced that they hope to repair both external vaults of the reactor by the end of the year to prevent them from leaking<ref>http://www.delfi.lv/news/national/politics/radioaktiva-udens-nopludes-draudus-salaspils-kodolreaktora-plano-noverst-lidz-gada-beigam.d?id=45159354 as of March 3, 2015</ref>. The vaults were built in the 1960s and  had never been checked before. The Government confirmed an initial grant of EUR 119 340 for this purpose, total costs were supposed to be known  later, after the Univerisity would have made a schedule. Works were expected to commence in November.<ref>http://www.delfi.lv/news/national/politics/radioaktiva-udens-nopludes-draudus-salaspils-kodolreaktora-plano-noverst-lidz-gada-beigam.d?id=45159354 as of March 3, 2015</ref>
 +
 
 +
In December 2014 a small leakage started from one of the vaults increased the level of tritium to 10 Bq/l. The limit is 100 Bq/l.<ref>http://www.delfi.lv/news/national/politics/vienai-no-salaspils-radioaktiva-udens-tvertnem-konstateta-neliela-noplude.d?id=45382694 as of March 3, 2015</ref>. The leakage was stopped, but in January 2015 the Ministry of Environment informed that there might have been another leakage, this time from the other vault<ref>http://www.delfi.lv/news/national/politics/radioaktiva-udens-noplude-iespejams-notikusi-ari-no-otras-salaspils-reaktora-tvertnes-zino-raidijums.d?id=45418816as of March 3, 2015</ref>.

Another potential threat is the main fuel tank as it is made of a lower quality material<ref>http://www.delfi.lv/news/national/politics/lu-nopietni-apsver-domu-partraukt-salaspils-kodolreaktora-apsaimniekosanu.d?id=45470514 as of March 3, 2015</ref>. Also there is a crack in one of the  outer walls, from the floor to the ceiling. It is so wide that it is possible to see through it<ref>http://skaties.lv/latvija/sabiedriba/finansejuma-trukuma-del-salaspils-kodolreaktors-netiek-pienacigi-uzglabati-apdraud-rigu-un-apkartni/
 +
as of March 3, 2015</ref>. Due to low funding the entire facility is operated by only nine people<ref>http://www.delfi.lv/news/national/politics/lu-nopietni-apsver-domu-partraukt-salaspils-kodolreaktora-apsaimniekosanu.d?id=45470514 as of March 3, 2015</ref>. The building itself is poorly maintained. The temperature inside it is only +10 C° in winter<ref>http://www.lsm.lv/lv/raksts/zinju-analiize/zinas/salaspils-kodolreaktors-10-gados-no-soliitas-demontazhas-paveikt.a92345/as of March 3, 2015</ref>, which is enough to prevent the water inside the reactor from freezing but not enough to keep the building in a good condition.
 +
 
 +
At the beginning of January 2015 the Government granted another EUR 15 000 for immediate maintenance works.<ref>http://www.delfi.lv/news/national/politics/pieskir-lidzeklus-neatliekamiem-darbiem-salaspils-kodolreaktora.d?id=45417084 as of March 3, 2015</ref>
 +
 
 +
On January 19, 2015, in a press conference, the University announced that they are considering to terminate their contract thus ceasing to be the opeator of SRR if they do not receive financial support from the Government. Maintenance of the facility costs approximately EUR 200 000 a year and it it too expensive for the University.<ref>http://www.la.lv/partrauks-ligumu-ar-lu-par-salaspils-kodolreaktora-apsaimniekosanu/ as of March 3, 2015</ref>
 +
 
 +
In February the Government announced that the sum of EUR 300 000 would be granted in 2015 for the maintenance of SRR<ref>http://skaties.lv/latvija/politika/valdiba-vienojas-ka-bistamais-salaspils-kodolreaktors-tiks-pilniba-demontets/as of March 3, 2015</ref>.
 +
 
 +
At the beginning of February 2015 it was announced that the Latvian Environment, Geology and Meteorology Center, Ltd. will became the operator again. The change is expected to take place in April 2015. However, the University is planning to continue the development of the cyclotron center.<ref>http://www.la.lv/partrauks-ligumu-ar-lu-par-salaspils-kodolreaktora-apsaimniekosanu/ as of March 3, 2015</ref>

The decomissioning process started in May 2008 when the spent fuel was sent to Russia. Decomissioning  was supposed to take five years. These plans were interrupted already at the end of 2008 when the country got into recession.<ref>http://www.delfi.lv/news/national/politics/vienai-no-salaspils-radioaktiva-udens-tvertnem-konstateta-neliela-noplude.d?id=45382694 as of March 3, 2015</ref>
 +
 +
Reports from 2010 and 2011 show that no funding was granted for this purpose although the new plan was to start the decomissioning in 2011 and finish it in 2015. Also there was no funding granted in 2012.<ref>http://www.delfi.lv/news/national/politics/salaspils-kodolreaktoru-lu-cer-nodot-lidz-vasaras-vidum.d?id=43150852 as of March 3, 2015</ref>

In October 2014 the Ministry of Environment informed that they are looking for all available sources of funding, not only EU funds.<ref>http://www.delfi.lv/news/national/politics/salaspils-kodolreaktora-likvidesanai-mekles-finansejumu-arpus-es-fondiem.d?id=45169436 as of March 3, 2015</ref>
 +
 +
In February 2015, after announcing addtional funding for the maintenace of SRR in 2015, the Government also announced plans to finally finish the decomissioning. The current costs are approximately EUR 5.5 million and the decommissioning should be completed in four years, commencing in 2016.<ref>http://skaties.lv/latvija/politika/valdiba-vienojas-ka-bistamais-salaspils-kodolreaktors-tiks-pilniba-demontets/ as of March 3, 2015</ref>
 +
 +
The source of funding is currently unclear as the Government is struggling to find funds already for the maintanance costs. The sum mentioned above, EUR 300 000, will be taken from funds for force majeure cases. The Government also informed they might need to sell some of state real estates.<ref>http://skaties.lv/latvija/politika/valdiba-vienojas-ka-bistamais-salaspils-kodolreaktors-tiks-pilniba-demontets/ as of March 3, 2015</ref>

After a  Government meeting the Prime Minister of Latvia Laimdota Straujuma said that the current situation is unacceptable and this issue should finally be sorted out.<ref>http://daugavasbalss.diena.lv/novadu-zinas/salaspils-novads/straujuma-neapmierinata-ar-salaspils-kodolreaktora-problemu-9128 as of March 3, 2015</ref>

Summary

Salaspils Research Reactor (SRR) is located in Salaspils municipality, 2 km from the centre of Salaspils city, 25 km from Riga, the capital. It was the only civilian research reactor in the Baltic States[12]. Neutron activation analysis, nuclear reaction research, researches in solid state radiation physics, radiochemistry and radiobiology were carried out there. They were mainly done for scientific and medical purposes.

The research reactor was originally built according to a former USSR design as a pool-type light water-water reactor with 2 MW nominal thermal power. Since 1975, after physical reconstruction of the reactor, the nominal thermal power of the reactor was increased to 5 MW. In 1995 the Cabinet of Ministers issued the Order No. 263 to shut down SRR. The operation license for the reactor was awarded until the end of 1999.[13]

The estimated amount of radioactive waste the decommissioning of SRR will generate is 1200 m³.[14]

There was a small radioactive waste storage on the site of SRR (1975-2005) where some parts dismantled from the reactor core were stored after reconstruction activities in 1975. After characterisation and re-packing all waste was transferred to the radioactive waste repository „Radons“ in Baldone. The spent fuel was sent to Mayak in Russia in May 2008 within a bilateral governmental agreement.[15]

Background Information

History

The story of Salaspils Research Reactor (SRR) starts in 1957 when Igors Kirko, the director of Institute of Physics of the Academy of Sciences, invited two academics to a meeting. His purpose was to make proposals for construction of large scientific objects in Latvia (then – Latvian Soviet Socialist Republic), which would be included in the plan for next seven years. One of the academics, Pēteris Prokofjevs, suggested to build a research reactor – he had recently visited an IRT-1000 reactor in Moscow and was deeply impressed.[16]

The proposal was sent to the Council of Ministers of the USSR who accepted it in spring 1958. Salaspils was chosen because it was claimed to meet the requirements the best. It was close to Riga, easily accessible from the capital, the site met requirements for construction of dangerous objects and earth there was not important for agricultural needs thus it could be used for the sanitary protection zone. Also Olaine, Baldone and Carnikava's polygon were named as potencial locations.

At first SRR was a regular construction site, but after a message for future generations was concreted in its foundation on May 27, 1960 in an official ceremony the government of Soviet Latvia proposed to turn SRR into a present from Latvian proletarians for the XXII Congress of the Communist Party of the Soviet Union in autumn 1961. The site became an object of high priority.

Construction of the reactor's pool was finished in spring 1961. Everything around the pool - walls, windows, floors – as well as the pool itself had to be cleaned otherwise all flecks of dust would become radioactive. It was done by the reactor's staff, who spent the whole summer cleaning. Cleaning was realized by joint works (also known as bees), which where mandatory and lasted a full working day – 8 hours. The most famous of them took place on April 22, 1961. Maybe because it was a Saturday 8 employees out of 37 did not attend the joint work at all, 7 later sneaked away.[17]

The first criticality took place on September 26, 1961 at 5.02 PM. After that the reactor was shut down and turned on again on October 9, 1961 when it was officially opened by both academics and government officials.

Operation/Technical Information

Blueprints and other documentation for SRR project were received from Kurchatov Nuclear Power Institute in Moscow, which offered to increase the reactor's nominal thermal power to 2 MW. This proposal was accepted by the presidium of the Academy of Sciences. In autumn 1960, graduates who had recently joined the reactor's staff pointed out that the standardized project is already out-of-date and persuaded the constructors to modify it. Graduates built a new device for preparation of 50 m³ of distilled water that was necessary for the pool. This device allowed to produce water much faster and was also cheaper than the original one. Another modification was the control room desk. In the original project only one person could work with it while in SRR two main workspaces and several extra workspaces were created.[18]

During the construction works the reactor was a secret object and was named “Object IRT”. Materials for the reactor were received from “post boxes”. For instance, “Post Box No.3” stood for fuel. The employees could not travel abroad, expect for business (conferences, etc.) and they were not allowed to meet foreigners alone, only in pairs. After such meetings both persons had to write down what they had talked about. Despite all secrecy around it, SRR was open for visitors after it was put into operation. It is presumed that more than 50,000 people, mostly pupils, have visited it between the 1960s-1990s.

From September 1961 until June 1973, when SRR was closed for reconstruction, the reactor used EK-10 fuel with 10 % enrichment. After the reconstruction, from July 1975 until October 1979, IRT-2M fuel with 90 % enrichment was used. From October 1979 until July 1989 IRT-2M and IRT-3M (also with 90 % enrichment) were used. Starting from July 1989 until June 1998 only IRT-3M was used.

Reconstruction works were necessary due to several reasons. One of them was the problem with EK-10 fuel. Its rods started to curve in the active zone of the reactor and created danger of loss of hermetism. Another problem was corrosion in the pool's aluminium vessel. Aluminium was replaced with stainless steel.[19] The Reactor's nominal thermal power was increased from 2 to 5 MW.

SRR was the only research reactor in Latvia. Neutron activation analysis, nuclear reaction research, researches in solid state radiation physics, radiochemistry and radiobiology were carried out there. They were mainly done for scientific and medical purposes.

Physicists from SRR cooperated with physicists from different research reactors, other nuclear facilities and institutes of physics in the Soviet Union (for example, in Leningrad, Moscow, Belarus, Georgia), had partners abroad (for instance, in Germany, France, the Czech Republic) and carried out contract jobs. Also the Reactor had trainees from Iraq, North Korea and Libya. Specialists from SRR have worked in Iraq and Libya.

1990s-2015

After the collapse of the Soviet Union in 1991 Russia stopped to sell uranium to SRR. However, it did not affect the reactor. SRR usually used 4-5 bundles per year but the administration always ordered 7-8. These reserves where still used in 1998 when the reactor was shut down.

The decision to close it was made in 1995. On May 16 the Cabinet of Ministers issued the order[20] to shut down SRR and requested to start the preparation of a concept for decommissioning. When asked to comment it, the government explained that nuclear energy and nuclear programs are not among state priorities. Safety reasons were also mentioned.[21]

The reactor was shut down on June 19, 1998 at 1.00 PM.

Decommissioning started in 2002.

Fuel, approximately 2,5 kg (2587,7 g,13 bundles of IRT-2M), was sent to Luch Production Association in Podolsk, Russia in May 2005.

Spent fuel – 78 bundles, radiation on the surface: 6000 R/h - was sent to Mayak Production Association , Russia three years later. The enterprise’s press service reported the train load of spent nuclear fuel to have arrived at Mayak on May 15, 2008.

Both of these deliveries were carried out based on an agreement between Latvia and Russia and in cooperation with the USA.

In 2013 the University of Latvia replaced the Latvian Environment, Geology and Meteorology Center, Ltd. as the operator of the facility, planning to develop a cyclotron center there. A cyclotron is a type of particle accelerator[22] and has several usages. In medicine it can be used for cancer treatment and diagnostics of cardio-vascular diseases[23]. University of Latvia also intended to export the developed medicinal products and conduce scientific researches. Export was considered because there are no cyclotron centers in neighbouring countries[24].

In October 2014 the University announced that they hope to repair both external vaults of the reactor by the end of the year to prevent them from leaking[25]. The vaults were built in the 1960s and had never been checked before. The Government confirmed an initial grant of EUR 119 340 for this purpose, total costs were supposed to be known later, after the Univerisity would have made a schedule. Works were expected to commence in November.[26]

In December 2014 a small leakage started from one of the vaults increased the level of tritium to 10 Bq/l. The limit is 100 Bq/l.[27]. The leakage was stopped, but in January 2015 the Ministry of Environment informed that there might have been another leakage, this time from the other vault[28].

Another potential threat is the main fuel tank as it is made of a lower quality material[29]. Also there is a crack in one of the outer walls, from the floor to the ceiling. It is so wide that it is possible to see through it[30]. Due to low funding the entire facility is operated by only nine people[31]. The building itself is poorly maintained. The temperature inside it is only +10 C° in winter[32], which is enough to prevent the water inside the reactor from freezing but not enough to keep the building in a good condition.

At the beginning of January 2015 the Government granted another EUR 15 000 for immediate maintenance works.[33]

On January 19, 2015, in a press conference, the University announced that they are considering to terminate their contract thus ceasing to be the opeator of SRR if they do not receive financial support from the Government. Maintenance of the facility costs approximately EUR 200 000 a year and it it too expensive for the University.[34]

In February the Government announced that the sum of EUR 300 000 would be granted in 2015 for the maintenance of SRR[35].

At the beginning of February 2015 it was announced that the Latvian Environment, Geology and Meteorology Center, Ltd. will became the operator again. The change is expected to take place in April 2015. However, the University is planning to continue the development of the cyclotron center.[36]

Decommissioning

The relevant technical co-operation project on decommissioning the research reactor was submitted to the IAEA for 1997/1998. There were 5 expert missions from the IAEA from July 1997 until June 1998. The conclusion was, that the total decommissioning and dismantling costs would amount to ECU[37] 17-20 millions.

In 2000, the following budget plan (price base 1998) statements for the decommissioning and dismantling of SRR were made.[38]:

  • The annual costs at the beginning of the decommissioning and dismantling project (1999-2000) would be comparatively low and amounted to approximately ECU 700,000 per year;
  • The costs during the licensing phase would be higher and amount to approximately ECU 1,940,000 in 2001 and ECU 2,780,000 in 2002.
  • The highest annual investments of approximately ECU 5,560,000 would be required in 2003, when the necessary additional equipment (fuel handling, waste treatment) would be delivered and the modifications at SRR have to be done.
  • Subsequently, the annual costs would decrease to approximately ECU 3,056,000 in 2004 (main tasks are the delivery of the transport and storage casks and the execution of the fuel reloading).
  • The annual costs during the final dismantling period amounts to approximately ECU 850,000 in the years 2005 to 2008 and would be covered by Latvian side.

Approximately 1200 m³ of waste would be generated during decommissiong.[39] It will be stored in "Radons".

The decomissioning process started in May 2008 when the spent fuel was sent to Russia. Decomissioning was supposed to take five years. These plans were interrupted already at the end of 2008 when the country got into recession.[40]

Reports from 2010 and 2011 show that no funding was granted for this purpose although the new plan was to start the decomissioning in 2011 and finish it in 2015. Also there was no funding granted in 2012.[41]

In October 2014 the Ministry of Environment informed that they are looking for all available sources of funding, not only EU funds.[42]

In February 2015, after announcing addtional funding for the maintenace of SRR in 2015, the Government also announced plans to finally finish the decomissioning. The current costs are approximately EUR 5.5 million and the decommissioning should be completed in four years, commencing in 2016.[43]

The source of funding is currently unclear as the Government is struggling to find funds already for the maintanance costs. The sum mentioned above, EUR 300 000, will be taken from funds for force majeure cases. The Government also informed they might need to sell some of state real estates.[44]

After a Government meeting the Prime Minister of Latvia Laimdota Straujuma said that the current situation is unacceptable and this issue should finally be sorted out.[45]

Miscellaneous

  • “IRT” stands for “Standardized Research Reactor”.
  • Before the reactor was put into operation, it was necessary to check the stability of its active zone's construction. That could be done by measuring vibrations in the pool, filled with distilled water. It created a problem for physicists – devices, necessary for such measuring, could be placed in the pool before adding the water, but how to remove them? Water could be emptied into drains, but, since it was distilled, preparation of new water would have been expensive and time consuming. Chemist Beno Eiduss suggested to save the water by using divers. At first this idea was rejected, but later implemented.[46]
  • The pool had a decorative lifebuoy near it because the staff believed that every pool needs a lifebuoy.[47]
  • At the beginning of the 1980s, a theatre group visited the reactor. They were staging a play, set in a nuclear power plant. Actors wanted to achieve better understanding of how a reactor works, what employees feel while executing their tasks. When the group was already leaving, Olģerts Kroders, the Theatre Director, asked – how about if we show the play here at SRR? Administration of the reactor agreed, but, being afraid of sanitary inspection, asked not to advertise the event. The play took place on April 18, 1981 and gathered around 200 people from the reactor and the Institute of Physics.
  • The message concreted in the foundation of SRR for future generations says: “On May 27, 1960, 20 years after the establishment of Soviet Latvia, 43 years after the October Revolution, three years after launching of the first artificial Earth satellite, at the beginning of the Nuclear Era, a foundation for a great building – nuclear reactor of the Institute of Physics of the Academy of Sciences – was made.”[48]
  • Since 2010, some documentation and equipment from SRR, including the control room desk, are exhibited in Latvian Museum of Energy.
