| Title | Procedural Acceptance Criteria for Diesel Driven Fire Pump Fuel Oil Viscosity Not Met |
| Event Description | In the process of performing an assessment of the Hope Creek diesel driven fire pump fuel oil supply, a review of the most recently performed fuel oil analysis was performed. This review identified that a fuel oil sample analysis performed on February 11, 2004, to satisfy the 92-day surveillance requirement specified in procedure NC.FP-AP.ZZ-0005, 'Fire Protection Surveillance and Periodic Test Program,' showed that the fuel oil did not meet the procedural acceptance criteria for viscosity (was low out of specification). The diesel driven fire pump was not declared inoperable at this time and no compensatory measures were put in place. Upon discovery of the out of specification fuel sample, the diesel driven fire pump was declared inoperable on April 27, 2004 at 1616 hours0.0187 days <br />0.449 hours <br />0.00267 weeks <br />6.14888e-4 months <br /> and compensatory measures were established. Although the diesel driven fire pump is inoperable due to failure to meet this acceptance criteria, engineering judgment based upon vendor recommended viscosity requirements and satisfactory surveillance pump performance indicates that the diesel driven fire pump would continue to operate and perform its necessary functions with the lower viscosity fuel oil.
Failure to declare the diesel driven fire pump inoperable and establish appropriate compensatory measures is contrary to the provisions of Hope Creek Operating License Section 2.C.7, 'Fire Protection'. This event is being reported in accordance with Hope Creek Operating License Condition 2.F which requires a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> notification for violation of the requirements of Section 2.C of the Operating License. The licensee notified the NRC Resident Inspector.
An investigation was performed regarding the out of specification fuel oil sample for the diesel driven fire pump that identified that the Chemistry procedure used to perform the fuel oil sample analysis contained testing criteria for viscosity that differed from the requirements of the testing criteria in procedure NC-FP-AP.22-0005, 'Fire Protection Surveillance and Periodic Test Program.' The Chemistry procedure required viscosity testing to be performed at 40 deg C and the Fire Protection surveillance procedure acceptance criteria requires testing for viscosity at 20 deg C. A fuel oil sample obtained on April 26, 2004 was re-analyzed using the required testing parameters of the Fire Protection surveillance procedure and was determined to be within acceptance criteria (satisfactory). A review of previous fuel oil sample analysis data back to August 2000 was performed and compared to the current testing results. The current test results were determined to bound the previous test data. Based on this information, the diesel driven fire pump fuel oil has been acceptable throughout this time period. The diesel driven fire pump was returned to an operable status and the impairment closed. Since the pump remained operable, there was no violation of the Fire Protection Program. The report for violation of License Condition 2.C.7 of the Operating License is being retracted. The licensee will be notifying the NRC Resident Inspector. Notified R1DO (A. Della Greca). |
