SUBJECT:

COLUMBIA GENERATING STATION - INSPECTION REPORT 50-397/01-09

Dear Mr. Parrish:

On March 23, 2002, the NRC completed an inspection at your Columbia Generating Station for the period December 30, 2001, through March 23, 2002. The enclosed integrated inspection report documents the inspection findings, which were discussed on January 3, January 17, February 14, and March 26, 2002, as described in Section 4OA6 with Mr. G. Smith and other members of your staff.

The inspections examined 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.

Within these areas, the inspectors examined a selection of procedures and representative records, observed activities, and conducted interviews with personnel.

Based on the results of this inspection, the NRC has identified an issue that was evaluated under the risk significance determination process as having very low safety significance (Green). The NRC has also determined that a violation is associated with this issue. A second issue, which was not evaluated using the risk significance determination process, was also identified. A violation was associated with this issue. These violations are being treated as noncited violations (NCVs), consistent with Section VI.A.1 of the Enforcement Policy. These NCVs are described in the subject inspection report. If you contest the violation or significance of these NCVs, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC 20555-0001, with copies to the Regional Administrator, U.S. Nuclear Regulatory Commission, Region IV, 611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Columbia Generating Station.

Since September 11, 2001, Columbia Generating Station has assumed a heightened level of security based on a series of threat advisories issued by the NRC. Although the NRC is not aware of any specific threat against nuclear facilities, the heightened level of security was recommended for all nuclear power plants and is being maintained due to the uncertainty about the possibility of additional terrorist attacks. The steps recommended by the NRC include increased patrols, augmented security forces and capabilities, additional security posts, heightened coordination with local law enforcement and military authorities, and limited access

Energy Northwest -2-of personnel and vehicles to the site. In February 2002, the NRC issued an order to all commercial power plants to implement interim compensatory measures for the generalized high-level threat environment. Some of the requirements formalize a series of security measures that NRC licensees had taken in response to advisories issued by the NRC. The order also imposes additional security requirements which have emerged from the ongoing security review.

The NRC continues to interact with the intelligence community and to communicate information to Energy Northwest. In addition, the NRC has monitored maintenance and other activities which could relate to the sites security posture.

In accordance with 10 CFR 2.790 of the NRCs "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 NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.gov/reading-rm/ADAMS.html (the Public Electronic Reading Room).

Should you have any questions concerning this inspection, we will be pleased to discuss them with you.

Sincerely,

/RA/

SUMMARY OF FINDINGS IR 05000397-01-09; on 12/30/2001-3/23/2002; Energy Northwest; Columbia Generating Station. Integrated Inspection Report; Access Control.

The report covers a 12-week period of routine resident inspection activities from December 30, 2001, through March 23, 2002. The inspection identified one finding of very low safety significance and a finding of No Color. Both findings were noncited violations. The significance of the findings is indicated by their color (Green, White, Yellow, or Red) using Manual Chapter 0609 Significance Determination Process" (SDP). The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described at its Reactor Oversight Process website at http://www.nrc.gov/NRR/OVERSIGHT/index.html. Findings for which the SDP does not apply are indicated by No Color or by the severity level of the applicable violation.

A. Inspector Identified Findings Cornerstone: Physical Protection

  • Green. The inspector identified a violation of the Facility Operating License, NPF-21, Section 2.E, for failure to fully implement and maintain in effect all provisions of the Commission approved physical security plan. On January 23, 2002, the inspector identified an inattentive security officer on post at the plant secondary alarm station. This condition violated provisions in the physical security plan which required the secondary alarm station be continuously monitored. The inattentiveness of the officer resulted in the temporary loss of secondary alarm station monitoring function. This violation is being treated as a noncited violation consistent with Section V1.A.1 of the NRC Enforcement Policy. This violation is in the licensees corrective action program as Problem Evaluation Request 202-0230 (Section 3PP2).

This issue was more than minor because it involved a failure to meet the requirements of 10 CFR 73.55 (f) and associated licencee security plan. The issue was of very low safety significance (Green) because it did not involve an actual facility intrusion and there have not been greater than two similar findings in the previous four quarters.

  • SL IV. The inspector identified a noncited violation of 10 CFR 50.70 (Inspections).

On March 21, 2002, the inspector identified that a security officer alerted other on-duty officers that an NRC resident inspector arrived onsite. The issue was more than minor due to the potential for impacting the NRC's ability to perform its regulatory function, including performing unannounced inspections. This Severity Level IV violation is being treated as a noncited violation, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation is in the licensees corrective action program as Problem Evaluation Request 202-0867 (Section 3PP2).

B. Licensee Identified Violations Two violations of very low significance were identified by the licensee and reviewed by the inspectors. Corrective actions taken or planned by the licensee appeared reasonable. These violations were listed in Section 4OA7 of this report.

Report Details Summary of Plant Status:

Energy Northwest operated the Columbia Generating Station at full power at the beginning of the inspection period. Full power operations continued until February 14, 2002, when Technical Specifications required a forced shutdown because of uncorrected issues associated with the Division II emergency diesel generator output breaker. The licensee completed corrective maintenance and restarted the reactor on February 23, 2002. The licensee operated the facility at full power until March 16, 2002. On March 16, 2002, Energy Northwest reduced reactor power to 65 percent and repaired a condensate booster pump seal and feedwater heating steam leaks. The licensee restored the unit to full power on March 18, 2002. The reactor operated at full power for the remainder of the inspection period.

On March 20, 2002, Energy Northwest determined two main steam line isolation valves were inoperable due to errors in the stroke timing test methodology. On March 21, 2002, the licensee requested an NRC Notice of Enforcement Discretion to continue reactor operation with the inoperable main steam isolation valves. The inoperable condition was associated with rapid closure times on two of the main steam isolation valves. The NRC approved the licensees request for enforcement discretion on the same day.

.2 Periodic Evaluation Reviews (Annual Inspection)

a. Inspection Scope The inspectors reviewed the licensees quarterly and semi-annual reports documenting the performance of the Maintenance Rule periodic effectiveness assessments for recent past. These periodic evaluations covered the period from January 1999 through September 2001.

The inspectors noted that the licensees program had monitored risk-significant functions associated with structures, systems, and components using reliability and unavailability. Additionally, the performance of nonrisk-significant functions were monitored using plant level criteria.

The inspectors reviewed the actions taken and conclusions reached by the licensee with regard to the use of industry-wide operating experience and the balance of reliability and unavailability for specific Maintenance Rule functions. The balance review was conducted by examining the licensees evaluation of all risk-significant functions that had exceeded performance criteria during the evaluation periods.

The inspectors also examined the licensees evaluation of program activities associated with the placement of Maintenance Rule Program risk-significant functions in Categories (a)(1) and/or (a)(2). Finally, the inspectors reviewed the periodic evaluation conclusions reached by the licensee for the following systems: standby service water; 480 Vac electrical distribution; 4160 Vac electrical distribution; postaccident monitoring function; process radiation monitoring system; emergency diesel generators; and the residual heat removal system.

Findings No findings of significance were identified.

.3 Identification and Resolution of Problems (Annual Review)

a. Inspection Scope The inspectors evaluated the licensees use of their corrective action process within the Maintenance Rule Program. This review was accomplished by examination of the performance evaluation requests listed in the attachment and a sample of screening activities related to past system and components failures or performance deficiencies.

The purpose of this review was to establish that the corrective action program was entered at the appropriate threshold and effectively utilized for the purposes of:

  • Starting the evaluation and determination of corrective action process when performance criteria was exceeded
  • Identifying and implementing the system, structures and components get-well plan

-10-b. Findings

.1 Two Main Steam Line Isolation Valves Inoperable On March 20, 2002, the licensee determined two inboard main steam line isolation valves (MSIVs) were inoperable due to closing stroke times greater than allowed by plant Technical Specifications (TS). TS Surveillance 3.6.1.3.6, Primary Containment Isolation Valves, required each MSIV to close within five seconds but no faster than three seconds. The three second TS limit ensured peak reactor vessel pressure and the minimum critical power ratio (MCPR) thermal limit did not exceed the reactor coolant system pressure and reactor core safety limits during the worst case transient. The licensee discovered an error in methodology used to measure stroke time. The licensee concluded MSIV MS-V-22A and MS-V22D exceeded the three second minimum isolation time after the last measured stroke times were corrected for the testing error.

The failure of the two MSIVs to meet TS Surveillance Requirement 3.6.1.3.6 would have required the isolation of the two corresponding main steam lines within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, per TS Action Statement 3.6.1.3.A, resulting in a plant shutdown.

The licensee identified the MSIV testing methodology error during a review of an Operating Experience (OE) Report from the Monticello facility. The OE was issued on December 11, 2000, and was entered into the licensees corrective action program as PER 201-0179 on January 31, 2001. From a review of the OE, the licensee determined the MSIV testing methodology incorrectly included circuit and valve actuator response times when the stroke times were measured. With the circuit response time subtracted from the measured times, MS-V-22A and MS-V22D were determined to have closure times of 2.74 and 2.88 seconds. While these stroke times were less than the 3 seconds specified in TS 3.6.1.3.6, the safety significance of the fast closure times were minimal.

The two other main steam line MSIVs closed within the allowed range (approximately 3.4 seconds). This resulted in the average closure time for the main steam lines of 3.1 seconds. The accident analysis modeled the four steam line isolations as one closing orifice. The average closure time of 3.1 seconds for all four main steam lines was within the bounds of the accident analysis. The licensee performed additional analysis and concluded that with closure times as short as 2.5 seconds, the resulting pressure only resulted in a 4 pounds per square inch (psi) increase in peak post transient reactor pressure. The current accident analysis included 36 psi margin to the Reactor Coolant Pressure Safety Limit. The licensee determined the peak transient MCPR was bounded by the load reject without bypass analysis with the fast closing MSIVs. This issue was considered unresolved pending completion of the NRCs review of the timeliness of the licensees corrective actions (URI 50-397-01009-01).

.2 Notice of Enforcement Discretion (NOED)

The licensee concluded the facility was in violation of TS 3.6.1.3, due to the fast MSIV closures, and a plant shutdown was required. On March 21, 2002, Energy Northwest requested and NRC granted a NOED for TS 3.6.1.3, pursuant to the NRC's policy regarding exercise of discretion for an operating facility, set out in Section VII.C, of the

"General Statement of Policy and Procedures for NRC Enforcement Actions" (Enforcement Policy), NUREG-1600. The NOED was effective pending the licensees

-11-submission and NRC approval of a TS amendment request revising TS Surveillance 3.6.1.3.6, allowing relaxed stroke times for the two affected MSIVs. The TS amendment was to remain in effect until startup from Refueling Outage 16 or until restart from a forced outage of greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The licensee determined that the NOED relaxation of minimum MSIV closure times would not result in exceeding MCPR or ASME vessel protection limits following an anticipated transient.

1R23 Temporary Plant Modifications (71111.23)

a. Inspection Scope During the week of January 14, 2002, the inspectors reviewed plant temporary modifications. This was to verify plant temporary modifications were correctly installed and properly reflected in plant documents, drawings, and procedures. The inspectors compared the temporary modifications against Final Safety Analysis Report and Technical Specifications requirements. The inspectors also reviewed postinstallation test results and reviewed the impact of selected temporary modifications on the permanent systems and interfacing systems. None of the temporary plant modifications installed at the time of the inspection were risk significant. The inspectors specifically reviewed the following temporary plant modifications:

C Temporary Modification 98-011, Standby service water pond sand filter C Temporary Modification 99-004, Remove fuses and lock out breakers for FD-V-10, -15,& -24.

a. Inspection Scope The inspectors performed tours of the primary and secondary alarm station to verify that alarms annunciate audibly and visually and that there was an indication of the type and location of the alarm.

b. Findings

.1 Security Officer Inattentive at the Secondary Alarm Station On January 23, 2002, the inspector identified an inattentive security officer while on post at the plant secondary alarm station. This condition was a violation of the Facility Operating License, NPF-21, Section 2.E, and CGS physical security plan. The physical security plan required the secondary alarm station be continuously monitored. The officers inattentiveness resulted in a temporary loss of the security monitoring function.

This issue was more than minor because it involved a failure of the licensee to meet the requirements of 10 CFR 73.55 (f) and associated licensee security plan. The issue was of very low safety significance (Green) because it did not involve an actual facility

-14-intrusion and there have not been greater than 2 similar findings in the previous four quarters. This violation is in the licensees corrective action program as Problem Evaluation Request 202-0230 (NCV 50-397/01009-02).

.2 Security Officer Announced the arrival and presence of an NRC inspector On March 21, 2002, the inspectors identified a violation of 10 CFR 50.70, Inspections, after a security officer announced to other on-duty officers that the NRC resident inspector had arrived on-site. The security officer stated that gatehouse officers have provided central alarm and secondary alarm station security operators advance notification of NRC inspection activities. The officer stated he was unaware of the prohibition restricting the announcement of NRC inspection personnel. The issue was more than minor due to the potential for impacting the NRC's ability to perform its regulatory function. This Severity Level IV violation is being treated as a noncited violation, consistent with Section VI.A.1 of the NRC Enforcement Policy. This violation is in the licensees corrective action program as Problem Evaluation Request 202-0867 (NCV 50-397/01009-03).

4. OTHER ACTIVITIES 4OA1 Performance Indicator Verification (71151)

.1 Reactor Related Performance Indicators a. Inspection Scope For reactor specific performance indicators, the inspectors utilized NEI 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 0, and independently verified the following performance indicator data by reviewing operator logs, maintenance records, and corrective action documents.

  • Coolant Specific Activity
  • Coolant Leak Rate
  • Unplanned scrams b. Findings No findings of significance were identified.

-15-4OA5 Other

.1 (Closed) URI 50-397/0106-01: Design of fire protection sprinkler system in emergency diesel generator rooms.

The inspectors identified a question regarding the placement of automatic fire suppression sprinklers in such a location that they would be subject to the heat plume and has suitable sensitivity coupled with the design and orientation of heat collectors attached to them.

Upon further review, it was determined that the Safety Evaluation Report, NUREG 0892, Supplement 3, accepted this present design and configuration of the emergency diesel generator room sprinkler system.

4OA6 Management Meetings Regional and resident inspectors conducted several exit meetings with members of licensee management staff during the inspection period. These exit meetings included:

  • January 3, 2002, the inspectors presented the results of the emergency action level and emergency plan changes inspection to Mr. R. Sherman, Acting Manager, Licensing, and other members of licensee management, during a telephonic exit interview. The licensee acknowledged the findings presented.
  • January 17, 2002, the inspectors presented the results of the Maintenance Rule inspection with Mr. G. Smith, and other members of management. The licensee acknowledged the findings presented.
  • On February 14, 2002, the inspectors presented the results of the ALARA planning and controls inspection to Mr. R. Webring, Vice President, Operation Support, and other members of licensee management. The licensee acknowledged the findings presented.
  • On March 26, 2002, the inspectors presented the results of the resident inspection with Messrs. R. Webring and S. Oxenford and other members of licensee management staff. The licensee acknowledged the findings presented.

The inspectors asked the licensee whether any materials examined during the inspections should be considered proprietary. No proprietary information was identified by the licensee.

4OA7 Licensee Identified Violations The following findings of very low significance were identified by the licensee and are violations of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG 1600, for being dispositioned as NCVs.

-16-NCV Tracking Number Requirement Licensee Failed to Meet (1) NCV 50-397/01009-04 Technical Specification 5.4.1.d required, in part, that written procedures for the fire protection program be implemented. Fire Protection Procedure, 15.1.19, Fire Protection System Flow Path Valve Exercise, Revision 12, required FP-V-72, standby gas charcoal adsorber deluge isolation valve, be locked open. Contrary to the Technical Specification and the fire protection program, this valve was locked in the closed position between January 12 and March 13, 2002, because of human performance error.

An operator failed to correctly reposition the valve during a previous surveillance. This issue had more than minor significance because the mispositioned valve resulted in loss of fire suppression capability to one standby gas charcoal absorber.

The inspectors determined the issue had very low safety significance (Green) because the charcoal absorber deluge system only provided defense-in-depth fire suppression capability and the standby gas treatment system was not required for postfire plant safe shutdown, as described in FSAR Appendix F, fire protection evaluation. The licensee placed this issue into the corrective action program as Problem Evaluation Request 202-0783.

(2) 50-397/0109-05 Technical Specification 5.4.1(a) requires procedures to implement the ALARA program. Procedure SWP-MAI-01, Work Management-Planning, Scheduling and Work Activities, Revision 10, implements ALARA planning.

Section 3.7.1 of the above procedure states, in part, if the job scope is changed, ensure all appropriate individuals/organizations who initially reviewed the work order task review it again and concur with the proposed amendment. On September 17, 2001, the licensee documented a task pertaining to motor operator refurbishment work on Reactor Feedwater Valves MO-65A and B that was worked outside the original work order task ALARA plan. Radiation protection ALARA personnel were not informed of the change to the work order task ALARA plan. The licensee originally estimated the exposure as 348 Person-Millirem, but the actual exposure was 1800 Person-Millirem. The failure to contact ALARA personnel to obtain their concurrence is a Technical Specification 5.4.1(a) violation. This event is described in

-17-the licensees corrective action program, reference PER 201-1983. This violation is being treated as a noncited violation.

The safety significance of this violation was determined to be very low (Green) by the Occupational Radiation Safety Significance Determination Process because there was no overexposure or substantial potential for an overexposure and the ability to assess dose was not compromised.
