Saito, G W

Physics tests were performed on PWR-1 Seed 2 between 6200 and 7900 EFPH to provide information on control rod bank critical positions and reactivity worths. excess reactivities, temperature coefficients, xenon transient characteristics, and core reactivity symmetry measurements. The 7528 EFPH reactivity worth measurements resulted in a pronounced increase of the rod bank worth at rod positions high in the core due to fuel depletion effects. Values of xenon-free excess reactivities at ambient and operating temperatures measured at 7528 EFPH were computed by graphical integration of control rod worth curves. The zero power temperature coefficient measured at 7528 EFPH continued to exhibit a behavior consistent with Seed 1 experience by decreasing in absolute magnitude during Seed 2 life. The average seed thermal neutron flux level inferred at 7528 EFPH from a xenon transient measurement continued the over-all increasing trend of Seed 2 flux values with core age resulting from fuel depletion control rod group reactivity worth measurements during a xenon transient were not observed to differ appreciably from previous measurements. The end of life core reactivity symmetry measurements at 7528 EFPH showed no appreciable asymmetrical radial fuel depletion and fission product poisoning effects to be in evidence. The blanket power share was higher during Seed 2 operation than predicted by depletion calculations. (M.C.G.)
