NUCLEAR PARAMETER SURVEY OF 100 EMW OMR

Technical Report ·
OSTI ID:4227036
Studies were performed to determine the variation of K/sub eff/ in a 100 Mw(e) OMR with temperature and enrichment for various fuel element sizes, maintaining the same amount of moderator inside the fuel element for all element sizes. For all cases considered the fuel element was located in a 6-in. by 6-in. unit cell. Fuel element sizes below 4.0 in. gave a positive temperature coefficient of reactivity. The rise of K/sub eff/ with enrichment is practically linear for all element sizes. (W.L.H.)
