- Summary:
- The first PBF-LOCA program nuclear blowdown experiment (LOC-11) consisted of three sequential tests conducted with four separately shrouded PWR 15 x 15 design fuel rods. The first test, LOC-11A, was facility checkout test during which no programmatic information was obtained. The test rod peak power prior to blowdown was 46 kW/m for the LOC-11B test and 68 kW/m for the LOC-11C test. Maximum measured peak surface temperatures were 890 K and 1030 K for LOC-11B and LOC-11C, respectively. RELAP4/MOD6 posttest analysis of LOC-11B and LOC-11C indicated that accurate predictions of measured peak cladding temperatures required the inclusion of the following models: (1) a low flow CHF prediction model to allow for relatively accurate prediction of the time to CHF, (2) an accurate fuel model to represent the initial stored energy, (3) a radiation heat transfer model to represent the radiant exchange of thermal energy between the fuel rod and the shroud.
