Thermal Analysis of the SNAP 6 Reactor

The following specific items are contained in this report: 1. Maximum fuel element thermal stress as a function of core power. 2. Maximum fuel and cladding temperature as a function of core power and exit NaK temperature for NaK ΔT's from 100°F to 400°F. 3. Pressure drop through core as a function of flow rate. 4. Fuel element swelling as a function of core power and fuel temperature. 5. Maximum reflector temperature as a function of core power. Thermal stress considerations limit the power in the SNAP 2 core to 150 kw and that in the SNAP 8 core to 1000 kw. The problem of fuel element expansion may lower these limits, e.g. for a 2% allowable expansion and a fuel temperature of 1100°F, the maximum power for a five year life of the SNAP 8 core becomes 500 kw.
