Description

This is the fifth in a series of reports presenting the status and deterioration rates of the B. D, DR, F, and H biological shields. The last previous reports covering the period 1959 through March 31, 1961, indicated no significant decreasing trends in the attenuating effectiveness of the biological (iron-masonite) shields. At that time the combination of increasing average helium percentages and adding fringe poison in the smaller reactors resulted in corresponding reductions in shield temperatures below previous levels. Since then, there has been both an increase in reactor power levels and a greater emphasis on reduction of helium usage. … continued below

Description

The last previous reports covering the period 1959 through March 31, 1961, indicated no significant decreasing trends in the attenuating effectiveness of the biological (iron-masonite) shields. At that time the combination of increasing average helium percentages and adding fringe poison in the smaller reactors resulted in corresponding reductions in shield temperatures below previous levels. Since then, there has been both an increase in reactor power levels and a greater emphasis on reduction of helium usage. Consequently, to limit biological shield temperatures and reduce the shield leakage, additional fringe poison has been employed for shield protection. This report covers the period from late 1960 through January 1, 1964.
