SUBJECT:

PEACH BOTTOM ATOMIC POWER STATION - NRC INSPECTION REPORT 50-277/01-15, 50-278/01-15

Dear Mr. Kingsley:

On February 16, 2002, the NRC completed an inspection at the Peach Bottom Atomic Power Station. The enclosed report documents the inspection findings which were discussed on February 21, 2002, with Mr. Jay Doering and other members of your staff.

This inspection was an examination of activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

Immediately following the terrorist attacks on the World Trade Center and the Pentagon, the NRC issued an advisory recommending that nuclear power plant licensees go to the highest level of security, and all promptly did so. With continued uncertainty about the possibility of additional terrorist activities, the Nation's nuclear power plants remain at the highest level of security and the NRC continues to monitor the situation. This advisory was followed by additional advisories, and although the specific actions are not releasable to the public, they generally include increased patrols, augmented security forces and capabilities, additional security posts, heightened coordination with law enforcement and military authorities, and more limited access of personnel and vehicles to the sites. The NRC has conducted various audits of your response to these advisories and your ability to respond to terrorist attacks with the capabilities of the current design basis threat (DBT). On February 25, 2002, the NRC issued an Order to all nuclear power plant licensees, requiring them to take certain additional interim compensatory measures to address the generalized high-level threat environment. With the issuance of the Order, we will evaluate Exelons compliance with these interim requirements.

In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/NRC/ADAMS/index.html (the Public Electronic Reading Room).

Mr. Oliver If you have any questions, please contact me at 610-337-5209.

Sincerely,

/RA/

Report Details SUMMARY OF

PLANT STATUS

UNIT 2 Unit 2 began this inspection period operating at 100% power and remained at or near that power except for scheduled power changes to support routine maintenance activities and rod pattern adjustments.

UNIT 3 Unit 3 began this inspection period operating at 100% power. On January 11, 2002, operators commenced a planned power reduction to approximately 17% to make repairs to a transformer associated with the main generator. Following repairs, the unit power was increased and reached 100% on January 16, 2001. On January 24, 2001, power was reduced to 72% due to a recirculation pump runback caused by a loose electrical connection in the associated control circuitry. Unit 3 was returned to approximately 100% on January 26, 2000. Unit 3 operated at approximately 100% power throughout the remainder of the inspection period except for scheduled power changes to support routine maintenance activities and rod pattern adjustments.

a. Inspection Scope

(71151)

The inspector reviewed the data for the residual heat removal unavailability performance indicator to ensure that Exelon met all requirements of the performance indicator from the fourth quarter 2000 to the fourth quarter 2001 for both units. The information contained in the data was compared against the criteria contained in Nuclear Energy Institute (NEI) 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 1, to verify that all conditions that met the NEI criteria, for system unavailability, were recognized, identified, and reported as a Performance Indicator.

b. Findings

No findings of significance were identified.

4OA3 Event Follow-up

.1 (Closed) LER 3-01-002-00: Less than Adequate Test Review Results in Low Pressure

Emergency Core Cooling Safety Function Degradation On November 16, 2001, the low pressure emergency core cooling safety function was degraded for approximately two hours as a result of having the A loop of low pressure coolant injection out of service due to an inoperable isolation valve and the concurrent inoperability of other emergency core cooling system equipment during the performance of a logic system functional test. This event was caused by an inappropriate review of the logic system functional test that led to continuation of the testing without appropriate compensatory measures when the A low pressure coolant injection system was inoperable. This issue has been entered into the licensees corrective action program as CR00083213 The results of the inspectors on-site review of this LER is described in Section 4OA7 of this report. This LER is closed.

.2 (Closed) LER 2-97-009-01: Unit 2 Reactor Scram Resulting from a Generator Lockout

Condition and Subsequent Turbine Trip Failure of the 2A Reactor Feedpump The revision of LER 2-97-009, discussed anomalies found with the 2 A reactor feedpump turbine trip system as well as several Engineered Safety Feature actuations associated with the turbine trip. The inspector performed an onsite review of this revised LER, when it was issued, and did not identify any new issues. This LER is closed.

.3 (Closed) LER 2-97-010-01: Failure of the 2A Reactor Feedpump Turbine to Trip

The revision of LER 2-97-010, discussed additional information and analysis that supported the conclusion that the reactor feed pump high level trip function would operate properly during an actual high reactor water level event. The inspector performed an onsite review of this revised LER, when it was issued, and did not identify any new issues. This LER is closed.

.4 (Closed) LER 2-99-006-01: Engineered Safety Feature Actuations Following the Turbine

Trip and the Requirements of 10 CFR 50.73 (a)(2)(i)(B) for Exceeding the Heatup Rate Specified by the Technical Specifications The revision of LER 2-99-006, updated the information addressing the cause of the heatup rate event. The inspector performed an onsite review of this revised LER when it was issued and did not identify any new issues. This LER is closed.

.5 (Closed) LER 3-99-002-01: Failure to Maintain Alarmed Access Control to a Safeguards

System Vital Area Door Upon Completion of Scheduled Maintenance The revision of LER 3-99-002 was submitted to correct the title and does not change the reportability requirements or any other information contained in the original submittal.

This LER is closed.

4OA6 Meetings

.1 Exit Meeting Summary

The inspectors presented the results of the inspection to Mr. J. Doering and members of Exelon's management on February 21, 2002. Exelon management acknowledged the findings presented. No proprietary information was identified.

4OA7 Licensee Identified Non-Compliance

The following findings of very low significance were identified by Exelon and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600 for being dispositioned as a Non-Cited Violation.

NCV Tracking Number Requirement Licensee Failed to Meet 50-277;278/01-15-01 Technical Specification 6.11 requires that the licensee implement radiation protection procedures. Procedure HP-C-310 requires workers to notify radiation protection personnel of radiological problems and follow written and oral radiation protection guidance including notifying radiation protection upon an electronic dosimetry alarm. During early January 2002, at least 5 individuals experienced dosimetry alarms and did not contact radiation protection. The matter was addressed by various corrective actions and entered into the corrective action process (CR No.

93464).

50-277/01-15-02 Technical Specification 5.4.1 requires written procedures be established, implemented, and maintained covering activities listed in Regulatory Guide 1.33. Regulatory Guided 1.33 includes procedures for performing surveillance tests on plant equipment. Contrary to the above, on November 16, 2001, operators did not verify compliance with Technical Specification 3.5.1 as required by ST-I-010-100, Residual Heat Removal (RHR) Loop Logic System Functional Test.

Specifically, with the 3A loop of RHR inoperable for automatic the low pressure coolant injection, on three separate occasions the operators did not verify compliance with Technical Specification 3.5.1. The first occurred when the 3'B RHR pump was also inoperable for approximately 30 minutes, the second was when the 3'D RHR pump was also inoperable for approximately 30 minutes and the third was when the 3'A core spray loop was also inoperable for approximately 40 minutes. Although all three occasions were contrary to the requirements of Technical Specification 3.5.1, technical specifications were not violated since no required actions were missed during the time frames in which the additional subsystems were inoperable. The licensee entered this issue into their corrective action program as CR 00083213.

This is being treated as a Non-Cited Violation.
