Dear Mr. Larson:

On September 30, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Beaver Valley Power Station (BVPS), Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on October 17, 2014, with you, 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 violation of NRC requirements which was of very low safety significance (Green). However, because of the very low safety significance, and because it is entered into your corrective action program, the NRC is treating this finding as a non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy. If you contest the non-cited violation 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 Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Beaver Valley Power Station. In addition, if you disagree with the cross-cutting aspect assigned to this finding, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region I, and the NRC Resident Inspector at Beaver Valley Power Station. In accordance with Title 10 of the Code of Federal Regulations (CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records component of the NRCs Agencywide Documents Access Management System (ADAMS).

SUMMARY

IR 05000334/2014004, 05000412/2014004; 07/01/2014 - 09/30/2014; Beaver Valley Power

Station, Units 1 and 2; Followup of Events and Notices of Enforcement Discretion This report covered a three-month period of inspection by resident inspectors and announced inspections performed by regional inspectors. Inspectors identified one finding of very low safety significance (Green), which was a non-cited violation (NCV). The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609, Significance Determination Process, dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310, Aspects Within Cross-Cutting Areas, dated December 19, 2013. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated July 9, 2013. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.

Cornerstone: Initiating Events

Green.

A self-revealing NCV of 10 CFR 50, Appendix B, Criterion V, Instructions,

Procedures, and Drawings was identified for FENOCs failure to have an adequate plant startup procedure. Specifically, 2OM-52.4A, Raising Power from 5% to Full Load Operation, did not adequately address plant startup with one condensate pump in operation. This led to an inability to adequately control steam generator (SG) level when the second condensate pump was started which required the operators to trip the reactor.

FENOC is in the process of implementing corrective actions to revise procedure 2OM-52.4A and to address the human performance errors associated with this event. Additionally,

FENOC entered the issue into their corrective action program as condition report (CR)2014-09256.

The finding is more than minor because it is associated with the procedure quality and human performance attributes of the Initiating Events cornerstone and affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations.

Specifically, the inadequate procedure led to SG level fluctuations that could not be adequately controlled when the second condensate pump was started, and required the operators to trip the reactor. The inspectors determined that this finding is of very low safety significance (Green), because while it did result in a reactor trip, it did not cause a loss of mitigation equipment relied upon to transition the plant from the onset of a trip to a stable shutdown condition. The finding has a cross-cutting aspect in Human Performance,

Challenge the Unknown, because FENOC operators did not stop when faced with uncertain conditions. Specifically, the adequacy of the procedure was not sufficiently questioned when the plant was not in the normal start up configuration of two running condensate pumps nor later when the condensate pump discharge header pressure low alarm occurred (H.11). (Section 4OA3)

Unit 1 Auxiliary Feedwater System Unit 2 Auxiliary Feedwater System Unit 1 Residual Heat Removal System Unit 2 Residual Heat Removal System Unit 1 Support Cooling Water System Unit 2 Support Cooling Water System To determine the accuracy of the performance indicator data reported during those periods, the inspectors used definitions and guidance contained in Nuclear Energy Institute (NEI) Document 99-02, Regulatory Assessment Performance Indicator Guideline, Revision 6. The inspectors also reviewed FENOCs operator narrative logs, CRs, mitigating systems performance index derivation reports, system health reports, and NRC integrated inspection reports to validate the accuracy of the submittals.

b. Findings

No findings were identified.

4OA2 Problem Identification and Resolution

Main article: IP 71152

.1 Routine Review of Problem Identification and Resolution Activities

a. Inspection Scope

As required by Inspection Procedure 71152, Problem Identification and Resolution, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that FENOC entered issues into the corrective action program at an appropriate threshold, gave adequate attention to timely corrective actions, and identified and addressed adverse trends. In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the corrective action program and periodically attended CR screening meetings.

b. Findings

No findings were identified.

.2 Semi-Annual Trend Review

a. Inspection Scope

The inspectors performed a semi-annual review of site issues, as required by Inspection Procedure 71152, Problem Identification and Resolution, to identify trends that might indicate the existence of more significant safety issues. In this review, the inspectors included repetitive or closely-related issues that may have been documented by FENOC outside of the corrective action program, such as trend reports, performance indicators, major equipment problem lists, system health reports, maintenance rule assessments, and maintenance or corrective action program backlogs. The inspectors also reviewed FENOCs corrective action program database for the first and second quarters of 2014 to assess CRs written in various subject areas (equipment problems, human performance issues, etc.), as well as individual issues identified during the NRCs daily CR review (Section 4OA2.1). The inspectors reviewed selected FENOC integrated performance assessment and trending (IPAT) reports for the first 6 months of 2014, conducted under NOBP-LP-2018, Integrated Performance Assessment and Trending, to verify that FENOC personnel were appropriately evaluating and trending adverse conditions in accordance with applicable procedures.

b. Findings and Observations

No findings were identified.

The inspectors review of the FENOC departments IPATs included technical services engineering, site protection, human performance, operations, plant and reactor engineering, and the site rollup. The inspectors determined that FENOC was identifying adverse trends and tracking the implementation of corrective actions that were developed as a result of the trends. The inspectors also noted new CRs were written for previous trends that had not made adequate improvement. The inspectors did not identify any adverse trends that had not been identified by FENOC.

.3 Annual Sample: Cold Weather Corrective Actions

a. Inspection Scope

The inspectors performed an in-depth review of FENOCs apparent cause analysis and corrective actions associated with CR 2014-00490, cold weather challenges both Beaver Valley Units. Specifically, severe cold weather in January 2014 led to a reactor trip, an inoperable train of river water due to frazil ice, and inoperable safety related indications.

The inspectors assessed FENOCs problem identification threshold, cause analyses, extent of condition reviews, compensatory actions, and the prioritization and timeliness of corrective actions to determine whether FENOC was appropriately identifying, characterizing, and correcting problems associated with this issue and whether the planned or completed corrective actions were appropriate. The inspectors compared the actions taken to the requirements of FENOCs corrective action program and 10 CFR 50, Appendix B. In addition, the inspectors interviewed plant personnel and reviewed procedure changes to assess the effectiveness of the implemented corrective actions.

b. Findings and Observations

No findings were identified.

FENOC determined that the causes were inadequate guidance to address extreme cold weather conditions and less than adequate accountability for plant engineering inspections to support winter preparations. The inspectors determined that FENOC appropriately identified the apparent causes of the cold weather issues and the proposed corrective actions which included revising the cold weather procedure to require verification that engineering has completed their cold weather inspections and developing a procedure for extreme cold weather were adequate to address the apparent causes. The inspectors review of corrective actions determined that the completed corrective actions adequately addressed the identified causes and the corrective actions that had not been completed were on schedule to meet the assigned due dates.

.4 Annual Sample: Reactor Coolant Pump B Increased Vibrations

a. Inspection Scope

The inspectors performed an in-depth review of BVPS staffs identification, evaluation and corrective actions related to vibration of the B reactor coolant pump (RCP-1B).

The purpose of the inspection was to determine whether BVPS staff identified problems at the appropriate threshold, entered the issues into their corrective action program, and evaluated the problems in sufficient detail to identify appropriate and timely corrective actions.

On October 18, 2013, BVPS operators issued CR 2013-16712 to document an increase in pump shaft vibrations for the RCP-1B. BVPS staff continued to monitor the RCP-1B vibrations as a part of diagnostic maintenance. BVPS staff initiated CRs CR 2013-16712 and CR 2013-19837 which described the problem, probable causes, and initial actions completed. The inspectors determined that corrective actions completed to date involved examination of the pump shaft to verify there were no indications of a shaft cracking, and to collect detailed vibration information every two months and evaluate the results for changes that may indicate shaft crack initiation.

During the week of June 23, 2014, after a set of periodic vibration measurements were taken, the inspectors met with the BVPS Vibrations Program Owner, the BVPS system engineer responsible for RCPs, and contractor personnel who conducted periodic RCP vibration measurements at BVPS Unit 1. The inspectors reviewed and discussed the history of vibration measurement of RCP-1B, the results for the test conducted in June 2014, plans for future measurements, and the significance of the vibration measurements. In addition, the inspectors reviewed the Westinghouse Vibration Analysis Report TR-RES-13-14 of the RCP vibration trending and measurements taken on RCP-1B as part of the RCP monitoring.

b. Findings

No findings were identified.

The inspectors determined BVPS staff identified this problem at an appropriate threshold, entered the issue into their corrective action program, and were implementing corrective actions to closely monitor pump performance to reasonably provide indication of problems prior to a shaft crack developing and affecting the pumps ability to perform its intended safety functions. Specifically, the inspectors noted that in 2013 the BVPS staff had identified an increase in vibrations for the RCP-1B, and implemented corrective actions involving periodic measurements and analysis to characterize changes in the vibration magnitude and significance. The inspectors review of ongoing test results indicated that as of September 12, 2014, measurements did not indicate significant increase in vibration magnitude or initiation of shaft crack initiation.

.1 (Closed) Licensee Event Report (LER) 0500334/2014-002-01: Containment Liner

Through-Wall Defect Discovered During Planned Visual Inspection This LER supplement documents typographical corrections from the initial LER that was documented in NRC Inspection Report 05000334/2013005. These LERs deal with containment leakage rate values due to through wall penetrations on the Unit 1 interior Reactor Containment Building steel liner. The as-left leakage rate was edited from 2395 standard cubic feet per day (SCFD) to 2393 SCFD and does not change the conclusions of the initial LER. No findings or violations of NRC requirements were identified during the review of the LER. This LER is closed.

.2 (Closed) LER 05000412/2014-001-00: Unacceptable Indication Identified During Reactor

Vessel Head Inspection On May 1, 2014, during the Unit 2 refueling outage (2R17), the results of the planned ultrasonic examinations performed on Penetration 41 of the reactor vessel head did not meet the applicable acceptance criteria. The indication was not through-wall. Primary water stress corrosion cracking of the Alloy 600 penetration tube material was determined to be the apparent cause of the flaw. The flaw in the J-groove weld was repaired by weld overlay in accordance with approved procedures. No findings or violations of NRC requirements were identified during the review of the LER. This LER is closed.

.3 (Closed) LER 05000412/2014-002-00: Manual Reactor Trip Due to High Steam

Generator Water Level On May 20, 2014, Unit 2 was performing a plant startup following its 17th refueling outage. A single condensate pump was in operation. As reactor power was raised, feedwater flow to the SG increased, requiring the start of a second condensate pump.

The start of the second condensate pump resulted in SG level oscillations. A manual reactor trip was inserted when it was recognized that trip criteria of 85 percent narrow range level in the A SG would be met. Due to low decay heat input, the main steam isolation valves were shut in order to limit the reactor coolant system cool down. Plant trip response was as expected without complications, and all control rods fully inserted in the core.

Introduction.

A self-revealing Green NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings was identified for FENOCs failure to have an adequate plant startup procedure. Specifically, 2OM-52.4A, Raising Power from 5% to Full Load Operation, did not adequately address plant startup with one condensate pump in operation.

Description.

On May 19, 2014, Unit 2 was in Mode 1, starting up the plant from refueling outage 2R17. One condensate pump was in service. Typically two are in service for a plant startup; however, because of multiple competing activities that had been in progress the previous few days, a second pump had not been started. The control room began raising power in accordance with 2OM-52.4.A, Raising Power from 5% to Full Load Operation. The B main feed water recirculation valve was placed in OPEN in accordance with the procedure. Since the A recirculation valve was already OPEN, one condensate pump was now supplying flow to the SGs through the bypass feed water regulating valves (BFRVs) and back to the condenser through both recirculation valves. The opening of the second recirculation valve caused condensate pump discharge pressure to lower. The drop in header pressure locked in the condensate pump AUTO start signal and the vertical board annunciator for condensate pump discharge header pressure low [392 pounds per square inch gage (psig)] at 1711.

A second condensate pump did not auto start because neither of the other two condensate pumps were in standby. The control room operators incorrectly concluded that the alarm was expected for operation with one condensate pump and did not implement the alarm response procedure to restore header pressure. Between 1711 on May 19, 2014 and 0445 on May 20, 2014, operations raised power from five percent to fourteen percent using control rods and condenser steam dumps. Condensate pump discharge pressure continued to lower, stabilizing at 325 psig (67 psig below the annunciator setpoint). Around 0400, the control room received the feedwater pumps suction pressure low status alarm on the plant computer. The reactor operator looked at the wrong indication on the vertical board and discussed the alarm with the unit supervisor. The unit supervisor referenced the overhead annunciator alarm response procedure for SG feed pump 21A/B suction pressure low and incorrectly determined that the alarm was not valid.

The oncoming dayshift operators noted the low condensate discharge header pressure and determined that additional condensate flow was required. The field operator contacted the control room to coordinate pump pre-start checks in accordance with 2OM-22A.4.C, Placing a Second Condensate Pump in Service. However, he was not given time to perform them and, at 0723, the A condensate pump was started. The discharge pressure and motor current parameters were not as expected and the pump was secured. The field operator determined that the discharge valve was shut. The field operator opened the A condensate pump discharge valve as well as performing the other pre-start checks. Operators placed the pump control switch in AUTO and the pump started. The increased condensate flow and pressure caused SG levels to fluctuate and the BFRVs were placed in manual. The control room operator attempted to gain control of SG level for the next 17 minutes, but was unsuccessful in controlling the A SG level. The SG level reached reactor trip criteria and operators tripped the reactor at 0835.

The inspectors concluded that procedure 2OM-52.4A was inadequate for one condensate pump operation because it resulted in the plant being placed in a condition where sufficient suction pressure could not be maintained to the feed pump. The operator action of starting the second condensate pump to address the low suction pressure created SG fluctuations that could not be adequately controlled.

Analysis.

The inspectors determined that FENOCs failure to have an adequate procedure for raising power from five percent to full load, as required by 10 CFR 50, Criterion V, is a performance deficiency that was within FENOCs ability to foresee and correct and should have been prevented. The performance deficiency is more than minor because it is associated with the procedure quality and human performance attributes of the Initiating Events cornerstone and affected the cornerstone objective of limiting the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the inadequate procedure led to SG level fluctuations that could not be adequately controlled when the second condensate pump was started and required the operators to trip the reactor.

In accordance with IMC 0609.04, Initial Characterization of Findings, and Exhibit 1 of IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power, the inspectors determined that this performance deficiency was of very low safety significance (Green), because while this issue did result in a reactor trip, it did not cause the loss of mitigation equipment relied upon to transition the plant from the onset of a trip to a stable shutdown condition.

The finding has a cross-cutting aspect in Human Performance, Challenge the Unknown, because FENOC operators did not stop when faced with uncertain conditions.

Specifically, the adequacy of the procedure was not sufficiently questioned when the plant was not in the normal start up configuration of two running condensate pumps nor later when the condensate pump discharge header pressure low alarm occurred (H.11).

Enforcement.

10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires, in part, that activities affecting quality shall be prescribed by documented procedures of a type appropriate to the circumstances and shall be accomplished in accordance with these procedures. Contrary to the above, prior to May 20, 2014, FENOC failed to have an appropriate procedure for raising power from five percent to full load with one condensate pump in operation. This deficiency eventually required the operators to trip the reactor when SG levels could not be adequately controlled. FENOC is in the process of implementing corrective actions to revise procedure 2OM-52.4A and to address the human performance errors associated with this event. Because this violation was of very low safety significance and FENOC entered this issue into their corrective action program, CR 2014-09256, this violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.
