Abstract
Advanced austenitic stainless steel beyond the standard composition re gion of SUS316 stainless steel PNC1520 has been successfully developed . Optimization of the steel leads to a composition of -20Ni-0.06C-2.5M o-1.7Mn-0.25Ti-0.1Nb-0.028P-0.004B through the alloying design and fab rication tests. An extensive series of evaluation tests including out- of-pile. sodium environment, neutron irradiation and fission product c orrosion has confirmed that PNC1520 is superior in high temperature st rength and irradiation resistance to PNC316 as a core material for the prototype reactor MONJU. PNC1520 is the best candidate material for t he Demonstration reactor and will be tested on the whole core scale in JOYO MK-M to obtain the proven data.
