American National Standard ANSI/ANS-8.6, Safety in conducting subcritical neutron---Multiplication measurement in situ

Creators

Description

There are many examples of expeditious and cost effective in situ measurements dating from the 1940's and 50's. These subcritical experiment, upon which the safety of operations were based, were paralleled by numerous critical experiments which provide most of the bases for computer code validations presently. As the capability to expeditiously and cost effectively perform critical experiments withers, in situ subcritical measurements may provide the information necessary to further reduce uncertainties and biases in safety margins and thus incorporate more safety and efficiency into process operations. Finally, certain site restoration activities may demand knowledge of the subcritical state before disturbing the buried material. In situ neutron multiplication measurements may offer the only practical means to this knowledge. This document discusses the standard of conducting subcritical Neutron-Multiplication measurements, in situ. 4 refs., 1 fig
