Water chemistry in reactor core environment is of great interest in structural materials integrity evaluation, because it plays an important role in corrosion behaviours of the materials. In order to provide significant information on stress corrosion crack growth behaviours, water chemistry tests under well quantified corrosive condition will be performed. In order to perform the tests, a new test facility is being constructed in the Japan Material Testing Reactor (JMTR). The tests will be performed under various conditions by changing water chemistry of feeding water, dose rate and flow rate at the irradiation test section etc. parametrically. The construction of the test facility will be finished in 2012 to start the tests.
