Clinton Power Station Assessment Results (Jan 1 - Dec 31, 2006) z Regulatory Response Action Matrix column due to 1 White finding and violation of 10 CFR 50 Appendix B Criterion III, Design Control, requirements.
z The White finding was issued as an apparent violation in November 2006 for failure to adequately address vortexing in the reactor core isolation cooling (RCIC) storage tank and its potential effect on the high pressure core spray (HPCS) and RCIC pumps.
13
Safety Significant Findings or PIs z Clinton modified the suction piping and associated instrumentation to ensure the RCIC and HPCS pumps would not be impacted by the vortexing condition.
z A Supplemental Inspection will be conducted in 2007 using inspection procedure 95001 to review Clintons root cause evaluation and associated corrective action plans.
14
Clinton Inspection Activities (Jan 1 - Dec 31, 2006) z NRC conducted approximately 1800 hours0.0208 days <br />0.5 hours <br />0.00298 weeks <br />6.849e-4 months <br /> of direct inspection and 4000 hours0.0463 days <br />1.111 hours <br />0.00661 weeks <br />0.00152 months <br /> of inspection activities at Clinton during CY 2006.
z Total of 6 Green Findings z 1 White Finding z No Substantive Cross-Cutting Issues z Refueling outage in February 2006 15
Clinton Inspection Activities (Jan 1 - Dec 31, 2006)
- In addition to baseline inspections the NRC performed the following inspections:
- Plant Modifications and 50.59 Program
- Tritium Contamination 16
Clinton Annual Assessment Summary January 1 - December 31, 2006 z Exelon operated Clinton Power Station in a manner that preserved public health and safety.
z All cornerstone objectives were met with one White finding identified (design control associated with potential impact of vortexing on HPCS and RCIC pump suction).
z NRC plans baseline inspections at Clinton for the remainder of the assessment period and a supplemental inspection for the White finding.
