SUBJECT:

EDWIN I. HATCH NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000321/2004002, 05000366/2004002

Dear Mr. Sumner:

On March 27, 2004, the US Nuclear Regulatory Commission (NRC) completed an inspection at your Hatch Nuclear Plant, Units 1 and 2. The enclosed integrated inspection report documents the inspection findings, which were discussed on April 6, 2004, with Mr. George Frederick and other members of your staff.

The inspection 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.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

This report documents one self-revealing finding of very low safety significance (Green). This finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance and because it was entered into your corrective action program, the NRC is treating this violation as a non-cited violation (NCV) consistent with Section VI.A of the NRC Enforcement Policy. Additionally, a licensee-identified violation which was determined to be of very low safety significance is listed in this report. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the United States Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Hatch Nuclear Plant.

In accordance with 10 CFR 2.390 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

SNC 2 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.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS

IR 05000321/2004-02, 05000366/2004-02; 12/28/2003 - 03/27/2004; Edwin I. Hatch Nuclear

Plant, Units 1 & 2; Maintenance Effectiveness The report covered a three-month period of inspection by resident inspectors and announced inspections by regional in-service inspection (ISI) and health physics inspectors. One Green non-cited violation was identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green.

A self-revealing non-cited violation (NCV) was identified for inadequate work instructions provided to workers to remove a section of Plant Service Water (PSW)piping. This resulted in spilling water on to the 2C Emergency Diesel Generator (EDG)relay panel causing an auto-start of the 2C EDG and subsequent inoperability.

This finding is more than minor because it adversely affected the equipment performance attribute of the Mitigating Systems cornerstone in that the water spillage affected EDG operability. The finding was determined to be of a very low safety significance because the required redundant equipment trains were operable and the 2C EDG was restored to operable status within the Technical Specification (TS) allowed outage time. (Section 1R12)

Licensee-Identified Violations

A violation of very low safety significance, which was identified by the licensee has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. This violation and corrective actions are listed in Section 4OA7 of this report.

REPORT DETAILS

Summary of Plant Status

Documents reviewed are listed in the Attachment.

b. Findings

No findings of significance were identified.

1R08 Inservice Inspection Activities

a. Inspection Scope

The inspectors observed inspection activities and reviewed the documentation and selected supporting records for ISI work activities conducted during Hatch Unit 1 refueling outage 21. This was the first outage of the 3rd period of the 3rd ISI interval.

The inspection activities, documentation, and supporting records were reviewed for compliance to the Technical Specifications (TS); the ASME Boiler and Pressure Vessel Code, Section XI, 1989 Edition, with no Addenda; and other appropriate industry and NRC guidance and standards.

The inspectors reviewed the following nondestructive examinations (NDE):

  • IVVI : Shroud Support Plate Gusset (SSPG)-1 @ 15 Degrees.

The inspectors also inspected the following NDE by record review:

  • UT - Weld No. 1B21-1MS-24A-8, Qualification and certification records for NDE procedures, examiners, and equipment and consumables (i.e., UT oscilloscopes, transducers, calibration blocks, and couplant; PT cleaner, penetrant, and developer) for the inspected ISI examinations were reviewed.

The inspectors reviewed the following recorded indications to ensure that they were dispositioned in accordance with ASME Code requirements:

  • UT - Weld No. 1B21-1MS-24C-15, Pipe to Valve, Limited exam due to welded attachment, 60-deg shear exam - 60% DAC RI - Root Geometry
  • UT - Weld No: 1G31-1RWCUM-6-D-14, 178% DAC RI - Root Geometry The inspectors reviewed the Owners Activity Report dated September 17, 2002, which contained the statement that No flaws or relevant conditions that required evaluation for continued service were identified during the Plant Hatch Unit 1, 1R20 Outage. To verify this report, the inspectors selected the UT data from IR20 outage for review. The inspectors reviewed the following data sets with recordable indications, which were all resolved as root geometry or counterbore indications. UT records with recordable indications were for welds: 1E11-2HX-A-1, 1E11-2HX-B-0, 1E11-2RHR-6B-RVD-19, 1E11-2RHR-16B-DS-11, 1E11-2RHR-20-RS-12, 1E11-2RHR-20B-D-4, and 1E11-2RHR-24A-BP-11.

The inspectors reviewed Maintenance Work Order (MWO) 10201673 for the repair of the 1E11-F060A Valve. This MWO involved the grinding out of an eroded area of the bonnet sealing suface, weld repair and re-machining. The inspectors reviewed the weld process sheets and inspection documentation for this weld repair of ASME Class 1 pressure boundary material.

The inspectors selected the following work packages from the licensees listing of ASME Section XI code repairs and replacements since the last refueling outage:

  • MWO 1030839701, Unit 2 PSW supply to Unit 1 PSW Division 1 Supply to Main Control Room A/C (air conditioning) Valve. Replacement of 7 feet of 4-inch diameter C-Steel pipe due to microbiological corrosion causing pin-hole leaks in the piping.

  • MWO 1020180101, Replace existing Control Room Chiller water regulating valves with direct acting valves. Add local indication of PSW header pressure. (ASME Cl 3 piping)

In addition to the ISI review, a sample of ISI issues in the licensees corrective action program were reviewed for adequacy. ISI inspection activities for all of the Southern Companys sites are controlled and conducted by representatives of the licensees corporate offices. Corrective actions are recorded in the corporate corrective action system rather than the local plant corrective action system. The inspectors reviewed the following Corporate Condition Reports (CCRs):

  • CCR 2004000086, Ultrasonic search unit outside qualified parameters of EPRI Table 1 for P.I.-UT-10. Corrective action: took search unit to EPRI for qualification.
  • CCR 2004000087, Calibration block (BC-188) designated by procedure for Jet-Pump ECT inspection was not the Cal block (BC-151) shipped with the equipment.

Corrective action: Modified procedure to allow use of calibration block supplied with equipment.

b. Findings

1R11 Licensed Operator Requalification

a. Inspection Scope

The inspectors observed the performance of simulator scenario LT-SG-51083-00 which included a Group 1 isolation, a reactor scram, the inadvertent start of HPCI, and a steam leak from HPCI requiring an emergency depressurization. The inspectors reviewed procedures 10AC-MGR-019-0S, Procedure Use and Adherence, and DI-OPS-59-0896N, Operations Management Expectations, to verify that the operators met expectations for formality of communication, procedure usage, alarm response, control board manipulations, group dynamics, and supervisory oversight. The inspectors attended the post-exercise critique to assess if the licensee identified performance issues were comparable to those identified by the inspectors.

b. Findings

No findings of significance were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

The inspectors reviewed the following two maintenance activities associated with structures, systems, and components to assess the licensees implementation of the Maintenance Rule (10 CFR 50.65) with respect to the characterization of failures and the appropriateness of the associated (a)(1) or (a)(2) classification. For the equipment problems identified below, the inspectors reviewed operator logs, associated Condition Reports (CR), MWOs and the licensees procedures for implementing the Maintenance Rule. The review was to determine if equipment failures were being identified, properly assessed, and corrective actions established to return the equipment to a satisfactory condition. Documents reviewed are listed in the Attachment.

  • MWO 1039002603, Cap off the Unit 1 Division I PSW supply to the 1B Diesel Generator

b. Findings

Introduction.

A Green self-revealing non-cited violation (NCV) was identified for inadequate work instructions provided to workers to remove a section of PSW piping.

This resulted in spilling water on to the 2C EDG relay panel causing an auto-start of the 2C EDG and subsequent inoperability.

Description.

On February 18, 2004, workers were removing a section of the PSW piping which normally supplies the 1B EDG. The work was controlled under MWO 1039002603 and Work Process Sheet (WPS) 03-026T-M002. The piping was located above the 2C EDG Relay Panel 2H21-P232, which contains safety-related relays for the EDG auto-start during events such as a loss of coolant accident or loss of offsite power.

When the workers removed the section of PSW piping, residual water in the pipe spilled on to the relay panel causing the 2C EDG to automatically start. As a result of the inadvertent start, the 2C EDG was subsequently declared inoperable. The licensee determined four relays were affected by water intrusion. Three relays required inspection, cleaning, and calibration. The fourth relay failed due to water intrusion and required replacement. The corrective actions for the relays were completed and the 2C EDG was tested satisfactorily within the allowed outage time.

The inspectors determined this event was caused by inadequate work instructions and precautions for maintenance workers performing maintenance near safety-related components. While some water spillage was expected during this work, the only instructions for protecting adjacent safety related equipment was listed in Item 5 of WPS 03-026T-M002, which stated Take special precautions to protect cable trays that could be damaged during work activities. Consider effects from welding, possible water drainage, and personnel access. There were no instructions or standing work practices that provided measures to prevent residual water in the PSW piping from affecting adjacent safety-related components.

Analysis.

This finding is more than minor because it adversely affected the equipment performance attribute of the Mitigating Systems cornerstone in that the water spillage affected EDG operability. The finding was determined to be of a very low safety significance because the required redundant equipment trains were operable and the 2C EDG was restored to operable status within the Technical Specification (TS) allowed outage time.

Enforcement.

10CFR50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, states that activities affecting quality shall be accomplished in accordance with documented instructions appropriate to the circumstances. Contrary to the above, the licensee failed to prescribe adequate instructions appropriate to the circumstances in that on February 18, 2004, the instructions contained in WPS 03-026T-M002 did not contain adequate guidance to ensure protection of the 2C EDG relay panel from water intrusion, which caused an inadvertent start of the 2C EDG and subsequent inoperability. Because the event was of a very low safety significance and has been entered into the licensees corrective action program (CRs 2004101943 and 2004103609), this violation is being treated as an NCV, consistent with Section VI.A of the NRC Enforcement Policy: NCV 05000366/2004002-001, Inadequate Maintenance Instructions Results in Emergency Diesel Generator Start and Inoperability.

1R13 Maintenance Risk Assessments and Emergent Work Evaluation

a. Inspection Scope

The inspectors reviewed the following seven Plan of the Day (POD) documents listed below to verify that risk assessments were performed prior to components being removed from service. The inspectors reviewed risk assessment and risk management controls implemented for these activities to verify they were completed in accordance with licensee procedure 90AC-OAM-002-0, Scheduling Maintenance, and 10 CFR 50.65 (a)(4). For emergent work the inspectors assessed whether any increase in risk was promptly assessed and that appropriate risk management actions were implemented.

  • POD for Week 1/9-16 including 2A EDG Outage
  • POD for Week 1/17-23
  • POD for Week 1/24-30
  • POD for Week 1/31-2/6

The inspectors also verified the modifications were installed in accordance with the temporary modification requirements.

b. Findings

No findings of significance were identified.

RADIATION SAFETY

Cornerstone: Occupational Radiation Safety (OS)

2OS3 Radiation Monitoring Instrumentation and Protective Equipment

a. Inspection Scope

Instrument Operability and Use. On February 23, 2004, the inspector reviewed the operability and use of selected portable Health Physics (HP) instrumentation. The inspector observed source checks and reviewed calibration information for two ion-chamber type survey meters. In addition, the inspector evaluated HP technician proficiency in selecting appropriate survey instruments and using them to perform gamma and neutron dose rate measurements in dry cask storage Radiation Areas.

OTHER ACTIVITIES

4OA2 Identification and Resolution of Problems

1. Problem Identification and Resolution (PI&R) Reviews

a. Inspection Scope

Daily Condition Report Review. As required by NRC Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. This review was accomplished by reviewing the licensees computerized database.

Annual Sample Review. The inspectors performed a detailed review of CR 2003112280. This CR documented the advanced corrosion on two of the four foundation bolts for the Unit 1 C RHRSW pump. The RHRSW pump required three of the four foundation bolts intact to remain operable. The review was performed to ensure the full extent of the issue was identified, an appropriate evaluation was performed, and appropriate corrective actions were specified and prioritized. The inspectors evaluated the CR against the licensees corrective action program as delineated in licensee procedure NMP-GM-002, Corrective Action Program, and 10 CFR 50, Appendix B.

b. Findings and Observations

No findings of significance were identified; however, the inspectors identified a corrective action program (CAP) weakness in tracking completion of corrective actions.

On March 28, 2001, the licensee documented in CR 2001002557 that there was significant corrosion on one foundation bolt for the 1B RHRSW pump and two foundation bolts on the 1C RHRSW pump. When the licensee concluded that the corrosion had no adverse impact on system operability, the CR was closed to MWO 1-01-00965. This MWO was initially classified as required maintenance, but later changed to elective maintenance. Consequently, the MWO was never implemented. On July 9, 2003, the licensee again documented in CR 2002007064 significant corrosion on the two foundation bolts on the 1C RHRSW pump. The licensee closed this CR to MWO 1-02-02521 referencing the corrosion evaluation performed for CR 2001002557. MWO 1-02-02521 was also classified as elective maintenance.

After reviewing the CAP procedures and discussing this issue with the licensee, the inspectors determined that once the CR was closed, there was no mechanism that tied the MWO to the CR to track completion of the corrective actions. Consequently, the corrective actions were untimely. The enforcement aspects of this condition are discussed in Section 4OA7.

2. Cross-Reference to PI&R Findings Documented Elsewhere

Section 4OA7 describes a licensee-identified NCV for failure to repair corroding bolts on a pump, resulting in the pump being declared inoperable for greater than the allowed outage time.

4OA3 Event Follow-up

1. (Closed) LER 05000321/2003003-003, Residual Heat Removal Service Water Pump 1C

Inoperable For Its Failure To Meet Seismic Requirements On November 17, 2003, the licensee declared the 1C RHRSW pump was seismically inoperable when it was determined that two foundation bolts were severely corroded and would not restrain the pump during a seismic event. The pump was declared inoperable from March 28, 2001 until bolt replacement on November 17, 2003. The out-of-service time for this pump exceeded the TS allowable 30 day out-of-service time. This issue is addressed in Section 4OA2. This problem was entered into the licensees corrective action program as CR 2003112280. The enforcement aspects of this condition are discussed in Section 4OA7.

2. Inadvertent Actuation of the Engineering Safety System

a. Inspection Scope

The inspectors observed licensee response to an inadvertent actuation of the Engineering Safety System (ESF) during hydrostatic testing of the reactor vessel. The inspectors followed the troubleshooting and evaluation of plant conditions during the event, including personnel interviews and data acquisition. As part of the followup to this event, the inspectors observed plant pressure and level chart recorders, Safety Parameter Display System data trends, system schematics and diagrams. This issue has been placed in the corrective action program. Documents reviewed are listed in the attachment.

b. Findings

No findings of significance were identified.

3. Inadvertent Auto-Start of the 1C EDG

a. Inspection Scope

The inspectors observed licensee response and troubleshooting efforts to an inadvertent auto-start of the 1B EDG during breaker removal of the 1F 4160V switchgear. The inspectors followed the troubleshooting and evaluation of plant conditions during the event, including personnel interviews and data acquisition. This issue has been placed in the corrective action program. Documents reviewed are listed in the attachment.

4OA6 Meetings, Including Exit

1.

Exit Meeting Summary

On April 6, 2004, the inspectors presented the inspection results to Mr. George Frederick and the other members of his staff who acknowledged the findings. The inspector confirmed that proprietary information was not provided or examined during the inspection.

2. Annual Assessment Meeting Summary

On April 6, 2004, the NRCs Chief of Reactor Projects Branch 2 and Senior Resident Inspector assigned to the Edwin I. Hatch Nuclear Plant (HNP) met with Southern Nuclear Operating Company to discuss the NRCs Reactor Oversight Process (ROP)and the NRCs annual assessment of HNP safety performance for the period of January 1, 2003 - December 31, 2003. The major topics addressed were: the NRCs assessment program and the results of the HNP assessment. Attendees included HNP site management, members of site staff, and corporate management. This meeting was open to the public. Information presented during the meeting is available from the NRCs document system (ADAMS) as accession number ML041040680. ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html.

4OA7 Licensee Identified Violations

The following violation of very low safety significance was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI.A.1 of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as NCVs.

  • TS 3.7.1 requires two RHRSW subsystems shall be operable. Contrary to this, on November 17, 2003, the licensee declared the 1C RHRSW pump inoperable when it was determined that two foundation bolts were severely corroded and would not restrain the pump during a seismic event. The pump was declared inoperable from March 28, 2001 until bolt replacement on November 17, 2003, exceeding the TS allowable 30 day out-of-service time. This problem was entered into the licensees corrective action program as CR 2003112280. This finding is of a very low safety significance because of the low frequency of earthquakes, and due to the redundancy available in the RHRSW system.
