Description
It is reported that antimony excursion occurs in Primary Heat Transport System (PHT) when oxidizing conditions are created by air ingress in PHWRs during unit shutdown. This results in increased radiation fields around the reactor components, making outage dose planning difficult, and contributing significantly to the radiation exposure of maintenance personnel. Knowledge of inventory of antimony in the reactor core will facilitate proper planning and implementation of dose reduction techniques. Present study attempts to estimate 124Sb activity in the primary coolant in scenario explained above by measurement of 122Sb activity in the spent fuel storage bay (SFSB) which attains equilibrium within a couple weeks subsequent to spent fuel discharge is started
