THE HELIUM PURIFICATION SYSTEM FOR THE PROPOSED 800 MWT PEBBLE BED REACTOR

PDF Version Also Available for Download.

Description

A helium coolant purification system was designed for the proposed 800 Mwt Pebble Bed Reactor. The purification system will operate on a coolant side steam with a flow rate 1% of the total coolant flow, and there are provisions for radioactive and nonradioactive contamination removal. Primary equipment components are dual oxidizers, an economizer heat exchanger, a gas cooler, dual absorbers, a fission-product gas-delay trap, and dual filters. The fission- product trap is sized to provide a hold-up of 30 min for krypton and 6 hr for xenon and for 99.9% retention of iodine. Nonradioactive decontamination is sufficient to maintain oxygen ... continued below

The fission- product trap is sized to provide a hold-up of 30 min for krypton and 6 hr for xenon and for 99.9% retention of iodine. Nonradioactive decontamination is sufficient to maintain oxygen bearing contamination at < 30 ppm in the coolant. Total cost of the system excluding auxiliary equipment and containment was estimated to be 6,360. (auth)
