METHOD OF STORAGE OF SPENT NUCLEAR FUEL WITH ENVELOPES OF ZIRCONIUM ALLOYS IN REACTOR-ADJOINING BASIN

摘要

FIELD: technique of storage of spent nuclear fuel in reactor-adjoining basins, in particular, corrosion-safe storage of spent nuclear fuel, provision of integrity of envelopes of spent heat-releasing assemblies. SUBSTANCE: donor of inhibitor-ferrous iron is introduced into the can to provide concentration of ferrous iron in the heat-transfer medium within 30 to 50 ug/l. Products of carbon steel: foil, wire, chips, filings, etc. can be used as a donor of ferrous iron in aqueous solutions. Ions of $$$, interacting with the products of radiolysis of $$$ and $$$, prevent both radiolytic development of $$$ and its accumulation in can water. EFFECT: enhanced corrosion resistance of envelopes of spent heat-releasing assemblies with envelopes of zirconium alloys at intermediate storage in cans of reactor-adjoining basins.
