Title: Fast reactor fluence dosimetry. Technical progress report, January--November 1976. [Neutron monitor based on helium production from (n,. cap alpha. ) reaction with /sup 10/B and /sup 6/Li]

Abstract

The objectives of this task are to: (1) develop and demonstrate the use of /sup 10/B and /sup 6/Li helium accumulation fluence monitors (HAFM's) as a reliable and accurate method of measuring reactor neutron fluence; (2) develop and apply an expanded set of HAFM's which will provide fluence responses in different but overlapping neutron energy ranges; (3) identify, through the precise measurement of spectrum-integrated helium production cross sections, those elements which produce significant helium when used individually or as components of advanced alloys in FTR and LMFBR neutron environments, so that their use might be eliminated, minimized, or controlled; (4) use this information to predict, with confidence, the helium production rate for any alloy or material considered for fast reactor use, and (5) maintain a centralized helium measurements laboratory available to the research community, and upgrade the sample throughput capacity to handle FTR dosimetry requirements.
