ZERO POWER TESTS ON NS SAVANNAH CORE 2

Given below are the results of a series of zero power tests performed on the NS SAVANNAH Core 2. 1. Core 2 elements have a maximum nonuniformity equivalent to plus or minus 50 gm U-235 per element. 2. The core has a shutdown margin of $3.5 plus or minus 0.2. 3. The instrument response during a core loading is similar to that for Core 1. 4. Rod pattern evaluation showed worths similar to those for Core 1. 5. The rod bank worth shape peaks sharply in the lower half of the core and is nearly constant in the upper half. 6. The temperature effect on reactivity between 16.9 C and 51.8 C is uniformly -0.78 percent/C. 7. Flux distribution is similar to that for Core 1 but with somewhat lower peaking factors. 8. The stuck rod margin is less than that for Core 1. Detailed flux maps are presented for tow rod patterns, and the partial water height method is compared with the boron poisoning method of rod evaluation.
