Evaluation of Impurity Behavior in the Reactor Water of a Boiling Water Reactor
Autor: Naoshi Usui, Nobuyuki Ohta, Hiroo Igarashi, Tsuneo Matsui, Shunsuke Uchida, Katsumi Ohsumi
Publikováno v: Nuclear Technology. 133:92-102
A system has been developed for evaluating the effect of impurity intrusion on reactor water as part of the chemistry diagnostic system for boiling water reactor water. Past records of anomalous changes noted in reactor water quality were first surve

Evaluation of Leachable Behavior from Ion Exchange Resins
Autor: Nishimura Yusaku, Hiroo Igarashi, Katsumi Ohsumi, Shunsuke Uchida, Tsuneo Matsui
Publikováno v: Journal of Nuclear Science and Technology. 36:443-450
The elution rate of leachables from ion exchange resin, which is used in condensate demineralizers and is one of several major sources of organic compounds in BWR cooling water, was measured. Properties of the leachables and elution rate depended on
