The program will take place from 2019 until 2021, the plan is for removal to begin in November of this year. Based on the contract, Kurchatov Institute will have to accomplish the following tasks:
- Conduct an inventory of SNF of wide range fuel assembles for research reactors and facilities (VVER, RBMK, VM, OK, AST, Romashka)
- Sort and identify SNF by type of fuel in a hot cell with the extraction of radioactive contents from the containers
- Pack new containers with SNF, fuel assembles or its elements separated by type and composition of the fuel in hot cell in accordance with established requirements for packaging design and transportation of nuclear materials
- Collect a batch of containers with at least 1072 spent fuel assembles
- Load batches into packaging containers and transport them for reprocessing to Mayak processing facility by special trains
The first batch will include at least 320 SNF assemblies. The majority of these assemblies will be removed from PNPI's WWR-M reactor in Gatchina, Leningrad Region. The smaller portion of 64 assemblies will be removed from the Moscow Institute.
Established in 1943 as Laboratory #2 of the USSR Academy of Sciences, the Kurchatov Institute was tasked with the development of nuclear weapons. Since the 1950s, the Institute has also worked on non-military nuclear energy technologies. The majority of research reactors at Kurchatov Institute have been in operation with highly-enriched uranium fuel since the late 1950s and early 1960s.
One of the major challenges with nuclear fuel at research facilities is that large share of this fuel has not been properly measured for accounting purposes and exact amount of nuclear materials is not known – this creates additional nuclear security vulnerability, as theft or other loss of nuclear material cannot be properly detected. Work under the subject contract includes taking inventory of SNF. According to Federal Norms and Rules NP-083-2015 Basic Rules of Nuclear Materials Accounting and Control widely known by its Russian acronym OPUK, which is referred in the contract as one of the documents establishing performance requirements, nuclear materials inventory taking implies confirmation of mass and isotopic composition of nuclear material. Hence, this contract can potentially help resolving the issue.
The contract stipulates that the removal of SNF accumulated for the past 70 years is intended to help resolving a series of nuclear legacy problems and improve the nuclear and radiation safety level for scientists, the population and the environment of the Moscow and Leningrad regions as well as reducing the risk of emergencies at nuclear and radiation hazardous facilities.
