A unique and optimal method for assessing the feasibility of employing chemical decontamination processes to remove crud from nuclear reactor primary systems without adversely affecting the integrity of the system components or piping during further reactor operation is disclosed. Materials used to construct such components and piping are exposed to several cycles of simulated decontamination processing with a test loop constructed to simulate a range of full system decontamination process conditions. The material specimens are then removed and tested to assure that the particular decontamination processing system has no adverse effects on the materials used.

System for qualification of chemical decontamination methods for

A fluid blast circuit interrupter is provided having a pair of compact toroidal-shaped nozzles, steady-state current-carrying contacts, arc-establishing contacts, and a blast valve. A rotatable cam plate provides independent actuation of the steady-state contacts, the arc-establishing contacts, and the blast valve mechanism in a variable and predetermined manner.
