Proryv Project

consists of a nuclear unit equipped with lead-cooled Brest-OD-300, and a terminal plant, which includes a module for reprocessing of irradiated mixed uranium-plutonium (nitride) fuel and a fabrication/re-fabrication module for fabrication of starting fuel assemblies (TAs) from imported materials, and further on - Fas made of recycled irradiated nuclear fuel. EDEC is intended to demonstrate the sustainable operation of the facilities that ensure the closing of the nuclear fuel cycle for the first time in the world. The construction at the same site of the reactor and facility for SNF reprocessing and fresh nuclear fuel fabrication enables to test the closed nuclear fuel cycle technology to the maximum extent and obtain the reference experience for the development of industrial-sale energy centers of high capacity.

• Fabrication and re-fabrication module
  The united module of fuel fabrication and re-fabrication allows to work with both source materials and products of SNF reprocessing of Brest-OD-300 reactor.
  Today, the construction of the fabrication and re-fabrication module is already in progress at the full pace. The development and approval of the design documentation has been completed along with erection of the main process buildings and structures. The unique process equipment that is unrivaled throughout the world has been produced and delivered to the site.
  To confirm the efficiency of the mixed uranium-plutonium nitride fuel assemblies the experimental FAs has been fabricated at the experimental facility SCC, which were installed in BN-600 reactor and passed the tests successfully.
• BREST
  The key element of EDEC is the world first innovative demonstration and industrial power unit based on Brest-OD-300 fast reactor with lead coolant that fully complies with the principles of "inherent safety".
  The reactor unit is designed in a way that totally presents any accident requiring evacuation of the public. For example, the reactor unit design allows to localize the coolant leaks within the reactor vessel and prevent the core uncovery.
  The Chief State Expert Examination gave a positive conclusion to the design documentation of the reactor unit BREST-OD-300.
• Reprocessing module
  EDEC reprocessing module is anticipated to gradually implement the combined technology of of spent mixed nitride fuel recycling. The final option of the spent nuclear fuel reprocessing with application of pyrochemical recycling is to be selected upom completion of a number of R&D activities.
