Irradiation assisted stress corrosion cracking (IASCC) is a degradation phenomenon caused by synergy of neutron radiation, aqueous environment and stress on in-core materials, and it is an important issue in accordance with increase of aged light water reactors. Isolating crack initiation stage from crack growth stage is very useful for the evaluation of the IASCC behavior. Hence facility for in-situ observation during slow strain rate test (SSRT) for irradiated material was developed. As performance demonstrations of the facility, tensile test with in-situ observation and SSRT without observation were carried out using unirradiated type 304 stainless steel in 561 K water at 9 MPa. The following were confirmed from the results. (1) Handling, observation and recording of specimen can be operated using manipulators in the hot cell. (2) In-situ observation can be performed in pressurized high temperature water and flat sheet type specimen is suitable for the in-situ observation. (3) Test condition can be kept constantly and data can be obtained automatically for long test period.

SSRT facility for in-situ observation in high temperature water of irradiated materials

Nakano, Junichi; Koya, Toshio; Endo, Shinya; Ugachi, Hirokazu; Tsuji, Hirokazu; Tsukada, Takashi

Proceedings of 11th International Conference on Nuclear Engineering (ICONE-11) (CD-ROM), P. 56, 2003/00

Irradiation assisted stress corrosion cracking (IASCC) is one of the key issues for the life management of light water reactor (LWR) core components. For understanding IASCC phenomenon, a slow stain rate testing (SSRT) facility with a capability for in-situ observation in high temperature water for irradiated materials was developed. The SSRT facility has an autoclave with a window for in-situ observation and has been designed for SSRT under boiling water reactor (BWR) condition. To simulate normal water chemistry (NWC) and hydrogen water chemistry (HWC) of BWR environment, dissolved oxygen and hydrogen concentrations (DO and DH) can be controlled within the range of 10 ppb to 32 ppm and 10 ppb to 2.8 ppm, respectively. Hydrogen peroxide can be injected into the autoclave to simulate the radiolysis of water in the reactor core. As a trial run, in-situ observation for an unirradiated material during tensile test in water at 561K was performed and it was confirmed that the load-elongation curve and images could be obtained successfully.
