Interim plutonium-238 criticality report for heat source system design

Technical Report ·
OSTI ID:5324546
; ;
In a fast neutron flux, preliminary studies indicate a critical mass of plutonium-238 comparable to that of plutonium-239. The quantity nu..sigma../sub f/ - ..sigma../sub a/, as measured in the Jezebel reactor, is 0.0118 +- 0.0006 cm/sup -1/ and 0.0117 +- 0.0004 cm/sup -/1 for plutonium-238 and plutonium-239 respectively. Using plutonium-239 fast fission parameters, planar and cylindrical critical array calculations for plutonium-238 heat sources are discussed.
