The current status of heat pipe R&D
Idaho National Laboratory under the Department of Energy–sponsored Microreactor Program recently conducted a comprehensive phenomena identification and ranking table (PIRT) exercise aimed at advancing heat pipe technology for microreactor applications.

Tungsten-184 is a useful dosimeter for thermal neutrons, particularly for high temperature applications. Correlation of neutron flux with 59Co activation and 235U fission density for short-term irradiations is shown. The 184W thermal-neutron capture cross-section in the Plum Brook Reactor was found to be 1.94 ± 0.08 b. Cadmium ratios for 184W are ∼⅕ of the value found for 59Co in differing spectral regions of the reactor. The radiochemistry and counting techniques for 185W are described.
