Research on technological assessment for ageing management of reprocessing plant
Description
The purpose of the research program is to provide review manuals and technical database for Ageing Management Technical Evaluation Reports performed by licensees of spent fuel reprocessing plants in accordance with ordinance on Periodic Safety Review. A research programs have been conducted based on a contract with well-equipped organization since F.Y.2006. Four experimental subjects on ageing phenomena listed bellow in this program for the technological assessment of TOKAI plant, which have experienced many corrosion problems. TOKAI plant is the pilot plant for reprocessing service commissioned in Dec. 1980 and shifted to R and D in Apr. 2006. Corrosion of stainless steel made components in boiling nitric acid solutions at heating portions. Corrosion of titanium alloy made components in nitric acid condensates at condensate portions. Hydrogen degradation of titanium alloy made components in highly radioactive nitric acid solutions. Creep and fatigue of nickel-base alloy made furnaces which is operated in the conditions of daily cyclic heating. (author)
