Description

As a result of research and development works of HTGR by JAERI, the high temperature engineering test reactor (HTTR) is expected to be constructed in the near future. As the reactor pressure vessel (RPV) material, 2 1/4 Cr-1 Mo steel will be used. Material characterization test has been carried out to evaluate the applicability of the 2 1/4 Cr-1 Mo steel to the RPV and to prepare for the licensing. The present paper summarizes the fracture toughness behavior including KId and KIa, irradiation embrittlement susceptibility and degradation of steel due to the long term aging at high temperature of the forged low Si 2 1/4 Cr-1 Mo steel. These tests reveal good fracture toughness which well meets the requirements of the ASME Code, low neutron irradiation embrittlement susceptibility, little embrittlement by long term aging and so on. The test results demonstrate good applicability to the RPV of HTGR. (orig./DG)
