| |
| Axial Flux Difference - Outside the Target Band.
| |
| This report was initiated by Incident Reports 81-505, 81-506, 81-507, and 81-508.
| |
| CONDITIONS PRIOR TO OCCURRENCE:
| |
| 12-19-81 Mode 1 - Rx Power 50% - Unit Load 580 MWe 12-21-81 Mode 1 - Rx Power 48% - Unit Load 560 MWe DESCRIPTION OF OCCURRENCE:
| |
| On four separate occasions, due to Load Rejection Testing, the Axial Flux Difference (AFD) shifted outside the +5% target band.
| |
| On December 19, 1981 at 0125, 0623, and 2220 hours, during power reductions of 75% to 50%, 75% to 57%, and 85% to 50%, the AFD d
| |
| shifted outside the target band and Action Statement 3.2.1.a.2 was entered. Again, at 2040 hours, December 21, 1981, a power-reduction from 85% to 48% shifted the AFD outside the target.
| |
| kand and the Action Statement was entered.
| |
| This occurrence constituted operation in a degraded mode in accordance with Technical Specification 6.9.1.9.b.
| |
| DESIGNATION OF APPARENT CAUSE OF OCCURRENCE:
| |
| As power decreased, the AFD shifted upward. At the same time, the rods going in pushed the flux downward, causing the AFD to shift out of the target band.
| |
| ANALYSIS OF OCCURRENCE:
| |
| Technical Specification 3.2.1.a.2 requires:
| |
| Power operation may continue provided the indicated AFD has not been outside of the +5% target band for more than 1 hour penalty deviation cumulative during the previous 24 hours, and the indicated AFD is within the limits shown on Figure 3.2-1. Otherwise, reduce thermal power within 30 minutes.
| |
| | |
| LER 130/03L CORRECTIVE ACTION:
| |
| After the control rods were in and the flux stabilized, the AFD shifted back into the +5% target band. At 0148, 0628, and 2248 hours December 19, 198T, and 2107 hours, December 21, 1981, respectively, Action Statement 3.2.1.a.2 was terminated.
