Abstracts

An integrated research project (IRP) for advanced instrumentation for Transient Reactor (TREAT) at Idaho National Laboratory (INL) was initiated. A task within the IRP is the continuing development of the Micro-Pocket Fission Detector (MPFD) as a real-time, in-core neutron flux sensor. Fissionable deposits of the MPFD need to be well characterized to provide accurate neutron flux measurements. Cross-calibration measurements of MPFD fissionable deposits were made using Back-to-Back Fission Chambers (BTBFC) as a method of characterization of fissionable deposits. BTBFC ratio and mass measurements are compared to the mass measurements reported by Kansas State University (KSU). BTBFC ratio measurements provided partial verification of the mass reported by KSU. BTBFC mass determinations indicated a discrepancy in comparison to KSU reported mass. Overall results indicate the need for further study on the use of the BTBFC in cross-calibration measurements as well as the need for destructive analysis of the MPFD fissionable deposits.
