To enhance safety due to exclusion of hydrogen formation and a possibility of subsequent explosion during severe accidents, a number of test and research efforts was taken to substantiate performance of stainless steels Kh18N10T and EI847 as the material for the WWER fuel rod cladding. To substantiate the use of stainless steels as the structural material for the WWER-1000 nuclear fuel and to evaluate the economic parameters, there was completed nuclear design of the reactor core with the new fuel options in the form of fuel rods and fuel assemblies. It was demonstrated that the use of stainless steels results in the need to increase uranium enrichment in fuel rods and to decrease the fuel cycle length. The performed economic evaluations of the fuel component in NPP electricity production demonstrate that replacement of zirconium alloys with stainless steels increases the electricity prime cost by 3-6%. Feasibility of enhancing WWER reactor safety by replacing zirconium alloys as the nuclear fuel structural material with stainless steels can be evaluated during a comprehensive cost effectiveness analysis of all NPP safety systems. In the area of absorber element development for NPPs and ZNPP Spent Nuclear Fuel Dry Storage Facility, based on the results of R&D activities completed under Stages 1 and 2, there was conducted a mass experiment on manufacturing of 1500 absorber elements for ZNPP Spent Nuclear Fuel Dry Storage Facility using the improved process. The results shown in this report evidence current importance and prospects of activities for development of the project Kh-4-3 and possibility of using the results obtained to develop core components (fuel rods, absorber rods, fuel assemblies, RCCA) for future Generation 3 WWER reactors.
