OMR NUCLEAR PARAMETER SURVEY

PDF Version Also Available for Download.

Description

A parameter survey was conducted on the Organic Moderated Reactor (OMR) to determine the nuclear effect of temperature, enrichment, fuel to moderator volume ratio, fuel element size, ard fuel element container variation. Temperatures ranged from 300 to700 deg F; enrichments from 1.5 to 1.9%; and fuel to moderator volume ratios from 0.1333 to 0.545. Fuel element sizes of 3.75, 4.5, and 5.5 in. were considered. The stainless steel fuel element container thickness was varied from 20 to 80 mils, and also 200 mil aluminum was substituted for the steel. Results were obtained as values of k/sub eff/ which ranged from ... continued below

The stainless steel fuel element container thickness was varied from 20 to 80 mils, and also 200 mil aluminum was substituted for the steel. Results were obtained as values of k/sub eff/ which ranged from 0.927 to 1.152 through 150 problems. It was concluded that fuel element size should be at least 4.1 inches, fuel to moderator volume ratio in the neighborhood of 0.30, and enrichment 1.7% assuming 8% excess k for poisoning, burnup, and control.
