tailieunhanh - Prolongation of the bor 60 reactor operation

The work included inspection of the equipment conditions, calculations and experimental research on operating parameters and the conditions of nonremovable components, investigation of the structural material samples after their long-term operation under irradiation, etc. Based on the results of the work performed, the residual lifetime was evaluated and the reactor operator made a decision to extend the lifetime period of the BOR-60 reactor | NuclEngTechnol 47 2015 253-2 59 Available online at ScienceDirect journal homepage http nuclear-engineering-and-technology Invited Article PROLONGATION OF THE BOR-60 REACTOR OPERATION ALEXEY L.

The BOR-60 reactor was put into operation in December 1969 and by the end of 2014 it had been operating on power for 265 000 hours. BOR-60 still demonstrates potential capabilities to extend the lifetime of sodium-cooled fast reactors. The BOR-60 lifetime should have expired at the end of 2014. Over the past few years a great scope of work has been performed to justify the possibility of extending its lifetime. The work included inspection of the Keywords equipment conditions calculations and experimental research on operating parameters and BOR-60 Reactor Core Damage Dose Neutron Fluence Prolongation Of Operation Reactivity Effect Safety Sodium Coolant Temperature the conditions of nonremovable components investigation of the structural material samples after their long-term operation under irradiation etc. Based on the results of the work performed the residual lifetime was evaluated and the reactor operator made a decision to extend the lifetime period of the BOR-60 reactor. After considering both a set of documents about the reactor conditions and the positive decision of independent experts the Regulatory Authority of the Russian Federation extended the BOR-60 operating license up to 2020.
