For many years, Sosny R&D Company has been cooperating with the Russian-design research centers abroad on different topics including supplying equipment. One of the large projects is the construction of a nuclear source facility driven by a linear electron accelerator at Kharkiv Institute of Physics & Technology (KIPT) of Ukraine.
The work was performed under the Russian Research Reactor Fuel Return program (RRRFR) and in connection with the preparation of Foton JSC radiation and technological complex (Tashkent, Uzbekistan), which comprised an IIN-3M research reactor, for decommissioning.
In 2014-2015, creation of a precision facility for profilometry and eddy-current testing of irradiated fuel rods to be used in a hot cell of RIAR State Scientific Center (SSC RIAR) was successfully completed.
In 2009-2013, Sosny R&D Company upgraded the radiation monitoring systems for Units 1 and 2 of the Beloyarsk NPP in order to ensure radiation safety in preparation for decommissioning of the Stage 1.
In 2012-2013 two precise automated systems for the hot cell were developed. This work was performed under the contract with Afrikantov OKBM as a part of development of equipment for the hot cell of the BN-800 reactor at Beloyarsk NPP.
Sosny R&D Company completed development, fabrication and commissioning of a subsystem for automated processing of task related monitoring data by order of the Beloyarsk NPP.
On June 29, 2009 transportation of SFA of Romania research reactor VVR-S of National Institute of Research and Development in Physics and Nuclear Engineering “Horia Hulubei” (IFIN-HH)
was successfully completed.
Implementation of the tasks of Global Initiative for Nuclear Threat Reduction started much before signing the declaration, in 2002. The first country from which the nuclear fuel containing HEU was removed was Serbia and Montenegro (Serbia now).
Together with Gidropress EDB, OKBM and SSC RIAR, R&D Company “Sosny” is involved in development of stands for inspection and repair of irradiated fuel assemblies of power reactors.
A peculiarity of the certification process was that the Russian Federation had to justify the package design safety in compliance with Russian regulatory requirements to accommodate Russian procedures to handling foreign casks at Russian facilities.
The Type C package is a packaging for air shipments of radioactive material without any restrictions on activity.
An SNF batch was removed from SSC IPPE in August, 2011 under the Federal Targeted Program “Ensuring Nuclear and Radiological Safety in 2008 and in the Period until 2015.
For the project purposes, it often needs to develop sophisticated and unique equipment to prepare the SNF for transportation and loading into casks.
In some projects, a sea shipment is the only possible way due to transit-associated complications. The first use of the Danish INF-2 class vessel LYNX equipped in compliance with the International INF Code was for the RRRFR shipment from Hungary.
As the TUK-19 casks can be transported in a multimodal manner, a transport overpack was designed for the purposes of unification of handling operations.
The AMB-100 and AMB-200 reactors at the Beloyarsk NPP were shut down in the 1980s. The fuel of about 40 types with a different burn-up has been stored in the NPP storage pools and at Mayak PA since then.
The Bilibino NPP has accumulated a large stock of SFAs stored in abundance in drained cooling pools. The planned shutdown of the plant raises an acute problem of further management of the spent fuel.
In early 2010, the absence of a technology for dry storage of non-conforming SNF of the RBMK-1000 reactor made Rosatom State Corporation initiate efforts to analyze safety of its reprocessing at Mayak PA.
The RA heavy-water reactor at the Vinca Institute of Nuclear Science, Serbia, was commissioned in the middle of the last century and shutdown more than 20 years ago.
The Paks NPP is located in the heart of Hungary on the Danube River. Over the years of operation of Russian VVER-440 units, the Paks NPP has demonstrated the best performance and efficiency. However, the NPP personnel have been concerned by the problem of magnetite deposits on the fuel rod cladding in the last few years.
