The effect of chemical composition on irradiation embrittlement
TL;DR: The Japanese Pressurized Thermal Shock (PTS) integrity study is now being conducted by the Japan Power Engineering and Inspection Corporation (JAPEIC) under contract with the Ministry of International Trade and Industry (MITI) as mentioned in this paper.

Verification of warm prestressing effect under a pressurized thermal shock (PTS) event
TL;DR: Fracture tests for the verification of WPS (warm prestressing) effect were carried out by using large flat specimens and big compact specimens with low toughness as discussed by the authors, and the results showed that WPS effect was confirmed even for the low-tough steel like reactor pressure vessel wall under neutron irradiation.

TL;DR: Fracture tests for the verification of WPS (warm prestressing) effect were carried out by using large flat specimens with very low toughness as mentioned in this paper, where tensile and bending loads and thermal shock were applied simultaneously to the specimens with the realistically postulated flaw and the two times larger one in order to make the maximum K{sub I} cross the lower bound of k{sub IC} data.

A crack arrest test using a toughness gradient steel plate
TL;DR: In this paper, a crack arrest test was carried out using a toughness gradient steel plate with three layers to study the concept of crack arrest toughness, and cracks were arrested at the boundary of the first and the second layers, except for a smallmore-» segment of the crack.

TL;DR: In this article, a steel plate with a toughness gradient was used to verify the crack arrest characteristics of a nuclear reactor pressure vessel (RPV) in laboratory scale, and the fracture test of this laminated steel plate confirmed that a running brittle crack will be arrested at the layer with higher toughness.
