Mr. Dennis Koehl President and Chief Executive Officer STP Nuclear Operating Company P.O. Box 289 Wadsworth, TX 77483

SUBJECT: SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION - NRC INTEGRATED INSPECTION REPORT 05000498/2014002 AND 05000499/2014002

Dear Mr. Koehl:

On April 4, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at the South Texas Project Electric Generating Station, Units 1 and 2, facility. On April 10, 2014, the NRC inspectors discussed the results of this inspection with Mr. G. Powell, Site Vice President, and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report. The NRC inspectors documented two findings of very low safety significance (Green) in this report. Both of these findings involved violations of the NRC's requirements. The NRC is treating these violations as non-cited violations (NCVs) consistent with Section 2.3.2.a of the NRC Enforcement Policy. If you contest these violations or significance of the 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, Region IV; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC resident inspector at the South Texas Project Electric Generating Station, Units 1 and 2, facility.

If you disagree with a cross-cutting aspect assignment or a finding not associated with a regulatory requirement in this report, 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 IV, and the NRC resident inspector at the South Texas Project Electric Generating Station, Units 1 and 2, facility. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, "Public Inspections, Exemptions, Requests for Withholding," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC's Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Enclosure:

Inspection Report 05000498/2014002 and 05000499/2014002 w/Attachment 1: Supplemental Information 2: Document Request for Occupational Radiation Safety Inspection 3: Document Request for Inservice Inspection Activities Electronic Distribution to South Texas Project

SUMMARY

IR 05000498/2014002, 05000499/2014002; 01/01/2014 - 04/04/2014; South Texas Project Electric Generating Station, Units 1 and 2, Inservice Inspection Activities; Problem Identification and Resolution; Event Follow-Up.

The inspection activities described in this report were performed between January 1 and April 4, 2014, by the resident inspectors at the South Texas Project and inspectors from the NRC's Region IV office. Two findings of very low safety significance (Green) are documented in this report. These findings involved a violation of NRC requirements. The significance of inspection findings is indicated by their color (Green, White, Yellow, or Red), which is determined using Inspection Manual Chapter 0609, "Significance Determination Process." Their cross-cutting aspects are determined using Inspection Manual Chapter 0310, "Components Within the Cross-Cutting Areas." Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process."

Cornerstone: Initiating Events

Green.

The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for an inadequate procedure associated with the boric acid corrosion control program (BACCP). Specifically, Procedure 0PGP03-ZE-0133, "Boric Acid Corrosion Control Program," Revision 7, failed to provide adequate screening criteria for boric acid leaks. As a result, the inspectors identified multiple instances where the licensee inadequately screened boric acid leaks by failing to take into account all the characteristics of the leak commensurate to the affected component. The licensee entered the finding into the corrective action program as Condition Report 14-5393. The inspectors determined that the failure to establish adequate screening criteria for boric acid leaks in Procedure 0PGP03-ZE-0133 was a performance deficiency. The finding is more than minor because it is associated with the procedure quality attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Using Inspection Manual Chapter 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," Exhibit 1, the finding was determined to be of very low safety significance (Green)because the assessment of degradation did not result in exceeding the RCS leak rate for a small LOCA and did not affect other systems used to mitigate a LOCA resulting in a total loss of their function. The inspectors determined the finding has a cross-cutting aspect in the area of human performance associated with conservative bias because the licensee failed to use decision-making practices that emphasize prudent choices over those that are simply allowable [H.14]. (Section 1R08)

Cornerstone: Mitigating Systems

Green.

The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for an inadequate procedure because train C essential chilled water system was rendered inoperable by failing to remove air from the system following maintenance. Specifically, the licensee failed to require a system fill and vent in Procedure 0PMP05-CH-003, "York Chiller Inspection & Maintenance 300 Tons," Revision 6, following maintenance on the essential chilled water system. The condition was placed into the corrective action program as Condition Report 13-12492. The licensee has modified the essential chilled water maintenance procedure to require a full system fill and vent following maintenance. The failure to require filling and venting of the essential chilled water system following maintenance that may introduce air into the system is a performance deficiency. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and adversely affected the objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, air left in the system rendered the train inoperable. Using Inspection Manual Chapter 0609, Appendix A, Exhibit 2, "Mitigating Systems Screening Questions," the inspectors determined the finding was of very low safety significance (Green) because the finding did not affect the design or qualification of the structure, system, and component; did not represent a loss of system or function; did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time; and did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety significant in accordance with the licensee's Maintenance Rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. The inspectors determined that the cause of the finding had a cross-cutting aspect in the resources area of human performance because the licensee did not ensure that this procedure was adequate to support nuclear safety by ensuring that the essential chilled water system was operable when it was returned to service [H.1] (Section 4OA2.2).

The inspectors also verified that the required inspection coverage was achieved and limitations were properly recorded. The inspectors reviewed whether the personnel performing the inspection were certified examiners to their respective nondestructive examination method.

b. Findings

No findings were identified.

.3 Boric Acid Corrosion Control (BACC) Inspection Activities

a. Inspection Scope

The inspectors reviewed the licensee's implementation of its boric acid corrosion control program for monitoring degradation of those systems that could be adversely affected by boric acid corrosion. The inspectors reviewed the documentation associated with the licensee's boric acid corrosion control walk-down as specified in Procedure 0PGP03-ZE-0133, "Boric Acid Corrosion Control Program," Revision 7, and Procedure 0PGP03-ZE-0033, "RCS Pressure Boundary Inspection for Boric Acid Leaks," Revision 12. The inspectors reviewed whether the visual inspections emphasized locations where boric acid leaks could cause degradation of safety significant components, and whether engineering evaluation used corrosion rates applicable to the affected components and properly assessed the effects of corrosion induced wastage on structural or pressure boundary integrity. The inspectors observed whether corrective actions taken were consistent with the ASME Code and 10 CFR Part 50, Appendix B requirements.

b. Findings

Introduction.

The inspectors identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for an inadequate procedure associated with the boric acid corrosion control program (BACCP). Specifically, Procedure 0PGP03-ZE-0133, "Boric Acid Corrosion Control Program," Revision 7, fails to provide adequate screening criteria for boric acid leaks.

Description.

The inspectors reviewed Procedure 0PGP03-ZE-0133 to verify that degraded or non-conforming conditions were being properly addressed to include identification, screening, and evaluation of boric acid leaks. Section 2.18 of the procedure defines SCREENING as "Activity to determine if leakage evidence could reasonably result in degradation of component function or qualification which would necessitate a BACCP Evaluation AND to recommend a cleaning, monitoring, insulation removal and/or repair schedule."

Section 4.1.3.1 states, "The purpose of the screening is to determine if the leakage is attributable to normal plant operation or to a degraded condition, to determine if a BACCP Evaluation is required, and to recommend a cleaning, monitoring, insulation removal and/or repair schedule. This activity is performed in parallel with normal Work Control Screening processes for material conditions." Section 4.1.3.2 c. states, "No qualification is required for this activity because of the rule-based, procedure-driven nature of the screening."

Procedure 0PGP03-ZE-0133, Section 4.1.3.7, includes the screening criteria for determining if a leak requires an evaluation. The procedure states that if any one of the following criteria is met, then the leak does not require an evaluation:

• Leakage deposit is dry with no evidence of corrosion products.

• Leakage deposits are from Expected Leakage.

• Leakage deposits are dry and only on components normally at room temperature.

• Leakage is Minor Leakage. The inspectors noted that the screening process is nonconservative because it is exclusive rather than inclusive, requiring only one of the boric acid leak criteria to be met to screen the leak out of an evaluation. However, failing to meet any of these conditions should require additional evaluation. Since the procedure requires no qualifications for the screening personnel, the potential exists that risk significant leaks could be inadvertently screened out. The inspectors noted that accepted industry standards, including the standard referenced by the licensee's procedure, recommend a process in which each of the defined criteria must be met to be able to screen out of an evaluation, rather than the less conservative method of meeting any one of the criteria.

The inspectors reviewed a sample of condition reports documenting previously identified boric acid leaks that had screened out of an evaluation. The review identified three instances where boric acid leaks screened out of the process but the visual condition, as seen in photos of the identified condition included in the condition report, did not support the description provided. The inspectors determined the licensee had inadequately screened the following leaks:

• CR 12-1898 - Leakage at residential heat removal Pump 1C casing drain flange. Dry deposits confined to flange area.

• CR 12-28378 - Residue buildup at the valve stem and inlet threaded connection for 1-RC-0214, reactor coolant system loop. Deposits are dry, white, and non-excessive and do not contact susceptible material.

• CR 13-5786 - Seat leakage past RC-0103 and RC-0163 to quick disconnect inlet. Deposits are dry, white and confined to joint.

The inspectors concluded that the boric acid leak documented in CR 12-1898 was not confined to the flange; the photos clearly showed the leak had moved down to a suction flange bolt of the RHR Pump 1C. Applying accepted industry standards, the inspectors determined that the leak documented in CR 12-28378 should have been classified as being excessive. Additionally, the inspectors concluded that the leak documented in CR 13-5786 was not confined to the joint, was excessive, and came into contact with a safety related carbon steel support. The inspectors discussed CR 13-5786 with the licensee and determined the leakage past values RC-0103 and RC-0163 had come into contact with a carbon steel support without being evaluated. As a result of the discussion, the licensee performed a visual examination (VT-3) of support RC 1003-HS5064 and determined that it was not degraded.

Based on these three examples, the inspectors determined that the licensee's screening process was not consistent with the industry standards as cited by the procedure and failed to identify potentially risk significant leaks for further evaluation that impacted safety-related structures, systems, and components.

Analysis.

The inspectors determined that the failure to establish adequate screening criteria for boric acid leaks in Procedure 0PGP03-ZE-0133 was a performance deficiency. The finding is more than minor because it is associated with the procedure quality attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the inspectors identified multiple instances where the licensee inadequately screened boric acid leaks by failing to take into account the characteristics of the leak commensurate to the affected component, and therefore could potentially affect the structural integrity of the affected or adjacent structure, system or component. Using Inspection Manual Chapter 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," Exhibit 1, the finding is determined to be of very low safety significance because the assessment of degradation did not result in exceeding the RCS leak rate for a small LOCA and did not affect other systems used to mitigate a LOCA resulting in a total loss of their function. The inspectors determined the finding has a cross-cutting aspect in the area of human performance associated with conservative bias because the licensee failed to use decision-making practices that emphasize prudent choices over those that are simply allowable. Specifically, the screening methodology established in Procedure 0PGP03-ZE-0133 resulted in multiple potentially risk significant leaks not receiving further evaluation [H.14].

Enforcement.

Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to the above, the licensee failed to implement procedural guidance of a type appropriate to the circumstances for screening boric acid leaks, an activity affecting quality. Specifically, Procedure 0PGP03-ZE-0133, "Boric Acid Corrosion Control Program," Revision 7, fails to provide adequate screening criteria for boric acid leaks. Because this violation is of very low safety significance and was placed in the corrective action program as CR 14-5383, this violation is being treated as a non-cited violation, consistent with Section 2.3.2.a of the NRC Enforcement Policy: NCV 05000498/2014002-01 and 05000499/2014002-01, "Failure to establish adequate screening criteria in the Boric Acid Corrosion Control Program."

b. Findings

No findings were identified.

1R13 Maintenance Risk Assessments and Emergent Work Control

a. Inspection Scope

The inspectors reviewed two risk assessments performed by the licensee prior to changes in plant configuration and the risk management actions taken by the licensee in response to elevated risk:

• Week of January 10, 2014, Unit 1, planned train A work week maintenance

• February 27, 2014, Unit 2, planned work week maintenance and the installation of a temporary instrument air compressor 24 The inspectors verified that these risk assessments were performed timely and in accordance with the requirements of 10 CFR 50.65 (the Maintenance Rule) and plant procedures. The inspectors reviewed the accuracy and completeness of the licensee's risk assessments and verified that the licensee implemented appropriate risk management actions based on the result of the assessments. The inspectors also observed portions of four emergent work activities that had the potential to cause an initiating event, to affect the functional capability of mitigating systems, or to impact barrier integrity:

• January 11, 2014, Unit 1, troubleshooting of an electrical ground on the train A vital AC bus

• Week of February 17, 2014, Unit 2, following the failure of instrument air compressor 24 and the planned work week maintenance activities

• March 6, 2014, Unit 2, following the failure of train A emergency diesel generator to remotely shut down due to failure of an air cylinder

• March 18, 2014, Unit 1, extended operation with the reactor coolant system in a solid water condition due to issues with not being able to lock out control rod D-6 for rapid refueling The inspectors verified that the licensee appropriately developed and followed a work plan for these activities. The inspectors verified that the licensee took precautions to minimize the impact of the work activities on unaffected structures, systems, and components.

These activities constitute completion of six maintenance risk assessments and emergent work control inspection samples, as defined in Inspection Procedure 71111.13.

b. Findings

No findings were identified.

1R15 Operability Determinations and Functionality Assessments

a. Inspection Scope

The inspectors reviewed five operability determinations and functionality assessments that the licensee performed for degraded or nonconforming structures, systems, or components (SSCs):

• January 20, 2014, Unit 1, operability determination of the personnel air lock due to an acrid smell and light smoke coming from an electrical relay

• February 4, 2014, Unit 1, operability determination of train C emergency diesel generator due to cooling water nitrates being in action level 2

• March 19, 2014, Unit 2, operability determination of train B emergency diesel generator due to 200 dpm leak of essential cooling water to the intercooler The inspectors reviewed the timeliness and technical adequacy of the licensee's evaluations. Where the licensee determined the degraded SSC to be operable or functional, the inspectors verified that the licensee's compensatory measures were appropriate to provide reasonable assurance of operability or functionality. The inspectors verified that the licensee had considered the effect of other degraded conditions on the operability or functionality of the degraded SSC. These activities constitute completion of five operability and functionality review samples, as defined in Inspection Procedure 71111.15.

b. Findings

No findings were identified.

1R18 Plant Modifications

.1 Temporary Modifications

a. Inspection Scope

The inspectors reviewed one temporary plant modification that affected risk-significant structures, systems, and components. On April 3, 2014, the inspectors reviewed a temporary modification that supplied power to the Unit 1 spent fuel pool cooling pump 1A during the train B electrical work window that removed normal power to the pump.

The inspectors verified that the licensee had installed and removed this temporary modification in accordance with technically adequate design documents. The inspectors verified that this modification did not adversely impact the operability or availability of affected SSCs. The inspectors reviewed design documentation and plant procedures affected by the modification to verify the licensee maintained configuration control.

These activities constitute completion of one sample of temporary modifications, as defined in Inspection Procedure 71111.18.

The inspectors observed the performance of the post-maintenance tests to verify that the licensee performed the tests in accordance with approved procedures, satisfied the established acceptance criteria, and restored the operability of the affected SSCs.

These activities constitute completion of eight post-maintenance testing inspection samples, as defined in Inspection Procedure 71111.19.

b. Findings

No findings were identified.

1R20 Refueling and Other Outage Activities

a. Inspection Scope

During the station's Refueling Outage 1RE18 that began on March 15, 2014, the inspectors evaluated the licensee's outage activities. The inspectors verified that the licensee considered risk in developing and implementing the outage plan, appropriately managed personnel fatigue, and developed mitigation strategies for losses of key safety functions. This verification included the following:

.2 Annual Follow-up of Selected Issues

a. Inspection Scope

The inspectors selected one issue for an in-depth follow-up:

• On October 27, 2013, Unit 1, train C essential chilled water system expansion tank level dropped below the minimum indication upon a start of the system. The inspectors assessed the licensee's problem identification threshold, cause analyses, extent of condition reviews and compensatory actions. The inspectors verified that the licensee appropriately prioritized the planned corrective actions and that these actions appear to be adequate to correct the condition.

These activities constitute completion of one annual follow-up sample, as defined in Inspection Procedure 71152.

b. Findings

Introduction.

The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for an inadequate procedure because the train C essential chilled water system was rendered inoperable by failing to remove air from the system following maintenance. Specifically, the licensee failed to incorporate a fill and vent step into their procedures after conducting maintenance on the essential chilled water system.

Description.

On October 27, 2013, while running essential chilled water pump 11C for nightly logs, the control room also received an essential chiller water expansion tank level LO alarm. An operator was dispatched to check the expansion tank level, but did not see any level in the sight glass. The control room operators secured the pump, and declared train C essential chilled water system inoperable and entered Technical Specification 3.7.14.

The licensee did not find any signs of a leak from the system. However, when operators went to vent the system as part of their troubleshooting efforts, they found significant amounts of air being vented from multiple locations. Operators reported vent times from as long as 35 seconds. The licensee conducted a fill and vent of the system and a satisfactory surveillance test before returning the system to an operable status. The licensee determined that air was introduced into the system and was trapped in a high point in the piping. When the pump was turned on, the air was swept through the system and into the expansion tank which caused the sudden drop in the expansion tank level.

The licensee's evaluation determined that this system had a history of similar issues, which sometimes caused the expansion tank to have an increased level, and operators would respond to the symptom by draining water to lower level; sometimes this later resulted in a low level on a subsequent system run. This evaluation concluded that air was being introduced through a leaking relief valve. Testing showed that the setpoint had drifted significantly lower than the required setpoint. However, the inspectors noted that this type of problem would not explain all the symptoms of the current example, and challenged the licensee's conclusions.

In response to the inspectors' questions, the licensee conducted a tier 2 apparent cause investigation to determine the source of the air. The licensee concluded that the lack of venting after testing the chiller unit with a hot water pack led to the introduction of air into the system. The licensee found that during major work on the system, a system venting is normally performed prior to returning the system to service. The most recent system venting for this train occurred on January 26, 2013, after a major train work week.

However, for smaller scope work, system venting may not be performed. On July 8, July 10, and October 3 of 2013, the licensee performed planned maintenance limited to the chiller unit. In each case, the final step was to conduct a refrigerant leak check using a hot water pack. The hot water pack is connected to the chilled water side via the drains while the isolation valves are shut. In accordance with chiller maintenance Procedure 0PMP05-CH-003, "York Chiller Inspection & Maintenance 300 Tons,"

Revision 6, once the testing is completed, the hot water pack is disconnected and the isolation valves are opened without any local venting. On October 4, 2013, the essential chilled water system was run and tested in accordance with Procedures 0PMP05-CH-003, and 0PGP03-ZM-0025A, "Post-Maintenance Testing Implementation," Revision 5. This test verified proper system acceptance criteria were met. There were no issues identified. The train C essential chilled water system was successfully run on October 25, 2013. On October 26, 2013, the control room received a chiller expansion tank HI level alarm. Operators responded and drained tank level.

On October 27, 2013, the chiller was again run for normal rotations when surge tank levels dropped below the indicating range. The chiller was secured and the system was vented. Operators discovered a fairly long vent time which suggested an abnormal amount of air in the system. The train C essential chilled water system was declared inoperable.

The inspectors concluded that this finding was appropriately categorized as being NRC-identified based on the inspectors' questions driving further evaluation of the cause after the licensee had reached their initial conclusions of the cause of the problems.

Analysis.

The failure to require a fill and vent of the essential chilled water system following maintenance that may introduce air into the system is a performance deficiency. The performance deficiency is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems Cornerstone, and adversely affected the objective to ensure availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.

Specifically, air left in the essential chilled in the system following maintenance rendered the train inoperable following system venting that discovered an unexpected higher than normal volume of air in the system. Using the Inspection Manual Chapter 0609, Appendix A, Exhibit 2, "Mitigating Systems Screening Questions," the inspectors determined the finding was of very low safety significance (Green) because the finding did not affect the design or qualification of the structure, system, and component; did not represent a loss of system or function; did not represent an actual loss of function of a single train for greater than its technical specification allowed outage time; and did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety significant in accordance with the licensee's Maintenance Rule program for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

The inspectors determined that the finding had a cross-cutting aspect in the resources area of human performance because the licensee did not ensure that the affected procedure was was adequate to support nuclear safety by ensuring that the essential chilled water system was operable when it was returned to service [H.1].

Enforcement.

Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," states, in part, "Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings." Contrary to the above, maintenance Procedure 0PMP05-CH 003, "York Chiller Inspection & Maintenance 300 Tons,"

Revision 6, used on July 8, July 10 and October 3, 2013, which directed activities affecting quality, was not appropriate to the circumstances. Specifically, Procedure 0PMP05-CH-003 did not include a step to fill and vent the essential chilled water system following maintenance. The failure to fill and vent the system resulted in the introduction of air into the system and the loss of expansion tank level indication.

This violation is being treated as an NCV, consistent with Section 2.3.2.a of the Enforcement Policy. The violation was entered into the licensee's corrective action program as Condition Report 13-12492. (NCV 05000498/2014002-02 , "Failure to Perform a Fill and Vent Results in an Inoperable Essential Chilled Water Train")

4OA3 Follow-up of Events and Notices of Enforcement Discretion

.1 (Discussed) Licensee event Report 05000498/2014-001-00: Overpower Condition Relating to the Ultrasonic Flow Measurement System In December 2013, engineering was investigating a negative trend in the correction factors for the ultrasonic flowmeter and discovered that both units had experienced feedwater pipe wall thinning that were outside the software allowances for accuracy of

the ultrasonic flowmeter. Power was reduced in both Unit 1 and Unit 2 to 99.6 percent power. The average feedwater pipe erosion near the ultrasonic flowmeter sensors was 60-80 mils (thousandths of an inch), compared to a nominal pipe wall thickness of 1.375 inches. In conjunction with the vendor, new transduces were fabricated, installed, and tested and both units were returned to 100 percent power. The licensee's initial evaluation determined that both units were operated in excess of licensed thermal power limits (1.8 percent for Unit 1 and 1.4 percent for Unit 2) for approximated 2.5 years. The licensee further determined that Technical Specification 3.3.1 allowed outage time was exceeded. The licensee submitted Licensee Event Report 2014-001-00, "Overpower Condition Relating to the Ultrasonic Flow Measurement System," on March 24, 2014.

Inspectors continue to evaluate the issue, and will track this item under Licensee Event Report 2014-001-00 and any subsequent revisions to this report. The inspectors discussed the licensee's ongoing evaluations to further assess the maximum power level achieved, which was expected to be lower than the initial evaluation. No findings were identified.

Existing information collection requirements were approved by the Office of Management and Budget, control number 3150-0011. Information Request January 22, 2014 Notification of Inspection and Request for Information South Texas Project Unit 1 NRC Inspection Report 05000498/2014002

On March 17, 2014, reactor inspectors from the Nuclear Regulatory Commission's (NRC) Region IV office will perform the baseline inservice inspection at South Texas Project Unit 1, using NRC Inspection Procedure 71111.08, "Inservice Inspection Activities."

Experience has shown that this inspection is a resource intensive inspection both for the NRC inspectors and your staff.

In order to minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection.

These documents have been divided into two groups.

The first group (Section A of the enclosure) identified information to be provided prior to the inspection to ensure that the inspectors are adequately prepared.

The second group (Section B of the enclosure) identifies the information the inspectors will need upon arrival at the site.

It is important that all of these documents are up to date and complete in order to minimize the number of additional documents requested during the preparation and/or the onsite portions of the inspection. We have discussed the schedule for these inspection activities with your staff and understand that our regulatory contact for this inspection will be Robyn Savage of your licensing organization.

The tentative inspection schedule is as follows:
