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.

Here we report how food-NaCl associative learning is affected by radiation exposure. Wild-type ${it C. elegans}$ strain was used for all experiments. The animals were irradiated with 0-500 Gy of $$gamma$$-rays. Irradiation did not affect chemotaxis toward NaCl, indicating that sensing and signaling in chemo-attraction are maintained in irradiated animals. It has been reported that chemotaxis was decreased by the association of starvation with chemical stimulation of NaCl. Chemotaxis of animals irradiated during the food-starved conditioning with NaCl was decreased than that of non-irradiated control and temporarily stopped. At several hours after irradiation, the decrease of chemotaxis in irradiated animals was observed again. These results suggest that irradiation perturbed and temporarily stopped a part of neuron network related to associative learning, but not that to chemo-attraction to NaCl.
