SUMMARY

IR 05000498/2015004, 05000499/2015004; 10/04/2015 - 12/31/2015; South Texas Project

Electric Generating Station, Units 1 and 2, Licensed Operator Requalification, and Problem Identification and Resolution The inspection activities described in this report were performed between October 4 and December 31, 2015, by the resident inspectors at the South Texas Project and inspectors from the NRCs Region IV office. Two findings of very low safety significance (Green) are documented in this report. One of 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, dated April 29, 2015. Their cross-cutting aspects are determined using Inspection Manual Chapter 0310, Aspects within the Cross-Cutting Areas dated December 4, 2014.

Violations of NRC requirements are dispositioned in accordance with the NRC Enforcement Policy, dated February 4, 2015. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process,

Revision 5.

Cornerstone: Mitigating Systems

Green.

The inspectors identified a finding, associated with simulator operability testing, for the failure of the licensee to track and incorporate actual plant data into their cyclic operability tests, as required by American National Standards Institute-3.5-2009, Nuclear Power Plant Simulators for Use in Operator Training and Examination. With the exception of one transient, the licensee exclusively used engineering analysis from the RETRAN code as baseline data without reference to plant events that may have been related to the required transient tests. This issue was entered into the licensees corrective action program as Condition Report 15-21463.

The failure to track and incorporate plant events into baseline data for simulator operability testing is a performance deficiency. It is more than minor and, therefore, a finding because it is associated with the human performance attribute of the Mitigating Systems Cornerstone and negatively affected the objective to ensure the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, if simulator performance is not being compared to the most relevant baseline data from the plant, the reliability of the simulator performance is reduced. Using Inspection Manual Chapter 0609,

Significance Determination Process, Phase 1 worksheets, and the corresponding Appendix I, Licensed Operator Requalification SDP (block 14), the finding was determined to have very low safety significance (Green) because it is a Simulator testing, maintenance, or modification deficiency. This finding has a cross-cutting aspect in the procedure adherence component of the human performance cross-cutting area because the licensee failed to ensure that individuals follow processes, procedures, and work instructions in that the American National Standards Institute-3.5-2009 guidance for selecting baseline data for simulator testing was not followed [H.8]. (Section 1R11.3)

Cornerstone: Emergency Preparedness

Green.

The inspectors identified a non-cited violation of 10 CFR 50.54(q)(2) for failure to maintain the emergency plan in accordance with the approved safety evaluation report.

Specifically, the licensee failed to meet 10 CFR 50.47(b)(2) requirements for timely augmentation of response capabilities, in accordance with the approved safety evaluation report. Following an update to the safety evaluation report in 1993, the licensee failed to update the emergency response organization staff augmentation time requirements to commence at the time of an emergency declaration vice from the time of an emergency notification. To restore compliance, the licensee updated the emergency plan in accordance with the current safety evaluation report.

Failure to maintain the site emergency plan in accordance with the approved safety evaluation report, dated May 20, 1993, was a performance deficiency. Specifically, the licensee failed to update the ERO staff augmentation time requirements to commence at the time of an emergency declaration, as required by the NRC safety evaluation report. This performance deficiency is more than minor because it is associated with the procedure quality attribute of the Emergency Preparedness Cornerstone and adversely affected the cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. This finding was evaluated using Inspection Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process (SDP), dated September 22, 2015, and was determined to be of very low safety significance (Green) per Table 5.2-1, Significance Examples 50.47(b)(2), because the staffing processes do not meet the threshold of routinely not capable of ensuring timely augmentation of the on shift emergency response staff to the extent that more than one required ERO functional area (in accordance with E-plan commitments) would not be filled. No cross-cutting aspect is assigned because the performance deficiency is not indicative of present performance.

(Section 4OA2.3)

PLANT STATUS

Unit 1 began the inspection period operating at 100 percent power. On October 18, 2015, Unit 1 entered Mode 3 to begin Refueling Outage 1RE19. On November 13, 2015, Unit 1 entered Mode 3, but identified a reactor coolant pump 1C high seal leak off from the number 1 seal and returned to Mode 5 later that day to replace the seal. On November 17, 2015, following the repair of the reactor coolant pump 1C seal replacement, Unit 1 entered Mode 3. On November 20, 2015, Unit 1 entered Mode 5 to evaluate issues regarding unreliable operation of control rod D-6. Following an NRC emergency license amendment review and approval, the licensee removed control rod D-6 from the reactor and entered Mode 3 on December 18, 2015. On December 20, 2015, Unit 1 closed main generator output breakers ending Refueling Outage 1RE19.

On December 21, 2015, while at 48 percent reactor power, main turbine governor valve number 2 began oscillating uncontrollably. Reactor operators tripped the main turbine. Following the main turbine trip, group one steam dumps failed to operate, which led to rising steam generator levels and resulted in a main feedwater isolation actuation. Reactor operators initiated a manual reactor trip, and entered Mode 3, due to the inability to maintain and control steam generator levels. Following repairs to the main turbine number 2 governor valve and the group one steam dumps, Unit 1 entered Mode 1 on December 24, 2015, and main generator breakers were closed on December 25, 2015. On December 30, 2015, Unit 1 reached 100 percent power and remained there for the remainder of the inspection period.

Unit 2 operated at 100 percent power for the entire inspection period.

These activities constitute completion of one quarterly licensed operator performance sample, as defined in Inspection Procedure 71111.11.

b. Findings

No findings were identified.

.3 Biennial Review

a. Inspection Scope

The licensed operator requalification program involves two training cycles that are conducted over a 2-year period. In the first cycle, the annual cycle, the operators are administered an operating test consisting of job performance measures and simulator scenarios. In the second part of the training cycle, the biennial cycle, operators are administered an operating test and a comprehensive written examination.

To assess the performance effectiveness of the licensed operator requalification program, the inspectors reviewed both the written examination and operating test quality, and observed licensee administration of an annual requalification test while on site. The operating tests observed included five job performance measures and two scenarios that were used in the current biennial requalification cycle. These observations allowed the inspectors to assess the licensee's effectiveness in conducting the operating test to ensure operator mastery of the training program content and to determine if feedback of performance analyses into the requalification training program was being accomplished.

On December 23, 2015, the licensee informed the inspectors of the completed cycle results for Units 1 and 2, for both the written examinations and the operating tests:

Thirteen of fifteen crews passed the simulator portion of the operating test

Eighty-three of eighty-five licensed operators passed the simulator portion of the operating test

Eighty-five of eighty-five licensed operators passed the job performance measure portion of the operating test

Eighty-two of eighty-five licensed operators passed the written examination The individuals that failed any portion of the exam were remediated, retested, and passed their retake examinations. Two operators have not completed their examinations due to extended medical leave, and their licenses have been placed in a suspended status pending completion of missed training and the requalification examinations.

The inspectors observed examination security measures in place during administration of the examinations (including controls and content overlap) and reviewed remedial training and re-examinations, as available. The inspectors also reviewed medical records of 12 licensed operators for conformance to license conditions and the licensees system for tracking qualifications and records of license reactivation for five operators.

The inspectors reviewed simulator performance for fidelity with the actual plant and the overall simulator program of maintenance, testing, and discrepancy correction.

The inspectors completed one inspection sample of the biennial licensed operator requalification program.

b. Findings

Failure to Track and Incorporate Actual Plant Data into Simulator Operability Testing

Introduction.

The inspectors identified a Green finding associated with simulator operability testing for the failure of the licensee to track and incorporate actual plant data into their cyclic operability tests, as required by American National Standards Institute (ANSI)-3.5-2009, Nuclear Power Plant Simulators for Use in Operator Training and Examination. With the exception of one transient, the licensee exclusively used engineering analysis from the RETRAN code as baseline data without reference to plant events that may have been related to the required transient tests.

Description.

During the week of September 14, 2015, while performing a biennial requalification inspection in accordance with Inspection Procedure 71111.11, Licensed Operator Requalification Program, the inspectors reviewed the baseline data sources used to evaluate simulator operability testing. South Texas Projects Simulator Configuration Control Procedure (0PNT01-ZA-0037), Section 4.5.5.2, requires that each fuel cycle, benchmark transient tests shall be conducted as delineated in ANSI-3.5-2009.

Section B.3.2 of ANSI-3.5-2009 lists 11 transient performance tests that must be performed such as a manual reactor trip, reactor coolant pump trip, maximum design load rejection, and others. Section 5.1.1 of ANSI-3.5-2009 requires that the baseline data against which the simulator is compared shall be used in the following order of preference: 1) actual plant data, 2) engineering analysis, 3) similar plant data, and 4) subject matter expert estimates. Contrary to this standard, South Texas Project cyclic simulator operability testing exclusively used engineering analysis from the RETRAN code without reference to plant events that may be related to the transients (with the exception of the manual reactor trip transient, for which South Texas Project had appropriately demonstrated equivalency with a 2002 plant event). The station does perform post-event simulator testing as required following actual plant events, but this is one-time testing that is not repeated, in contrast with cyclic operability testing which is repeated after each fuel load. Because the station was not actively incorporating plant data into cyclic simulator operability testing at the time of the sample, the station was unable to provide a list of relevant plant events that might qualify as baseline data.

This issue was entered into the licensees corrective action program as Condition Report 15-21463.

South Texas Projects Simulator Configuration Control Procedure (0PNT01-ZA-0037),

Section 4.5.5.2, requires that each fuel cycle, benchmark transient tests shall be conducted as delineated in ANSI-3.5-2009. Section 5.1.1 of ANSI-3.5-2009 requires that the baseline data against which the simulator is compared shall be used in the following order of preference: 1) actual plant data, 2) engineering analysis, 3) similar plant data, and 4) subject matter expert estimates. Contrary to the above, the licensee failed to actively track and incorporate actual plant data into cyclic simulator operability testing, instead relying on engineering analysis exclusively. This issue was entered into the licensees corrective action program as Condition Report 15-21463.

Analysis.

The failure to track and incorporate plant events into baseline data for simulator operability testing is a performance deficiency. It is more than minor and, therefore, a finding because it is associated with the human performance attribute of the Mitigating Systems Cornerstone and negatively affected the objective to ensure the reliability and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, if simulator performance is not being compared to the most relevant baseline data from the plant, the reliability of the simulator performance is reduced. Using Inspection Manual Chapter 0609, Significance Determination Process, Phase 1 worksheets, and the corresponding Appendix I, Licensed Operator Requalification SDP (block 14), the finding was determined to have very low safety significance (Green) because it is a Simulator testing, maintenance, or modification deficiency. This finding has a cross-cutting aspect in the procedure adherence component of the human performance cross-cutting area because the licensee failed to ensure that individuals follow processes, procedures, and work instructions in that the ANSI-3.5-2009 guidance for selecting baseline data for simulator testing was not followed [H.8].

Enforcement.

This finding does not involve enforcement action because no violation of a regulatory requirement was identified. Because this finding does not involve a violation and is of very low safety or security significance, it is identified as FIN 05000498/2015004-01; 05000499/2015004-01-01, Failure to Track and Incorporate Actual Plant Data into Simulator Operability Testing.

4OA2 Problem Identification and Resolution

Main article: IP 71152

.1 Routine Review

a. Inspection Scope

Throughout the inspection period, the inspectors performed daily reviews of items entered into the licensees corrective action program and periodically attended the licensees condition report screening meetings. The inspectors verified that licensee personnel were identifying problems at an appropriate threshold and entering these problems into the corrective action program for resolution. The inspectors verified that the licensee developed and implemented corrective actions commensurate with the significance of the problems identified. The inspectors also reviewed the licensees problem identification and resolution activities during the performance of the other inspection activities documented in this report.

b. Findings

No findings were identified.

.2 Semiannual Trend Review

a. Inspection Scope

The inspectors reviewed the licensees corrective action program, performance indicators, system health reports, list of essential cooling water leaks, condition reports associated with the main cooling reservoir, outage performance indications, hot work activities, outstanding work orders, and other documentation to identify trends that might indicate the existence of a more significant safety issue. The inspectors also interviewed licensee personnel. The inspectors verified that the licensee was taking corrective actions to address identified adverse trends.

These activities constitute completion of one semiannual trend review sample, as defined in Inspection Procedure 71152.

b. Observations and Assessments The inspectors review of the possible trends noted above produced the following observations and assessments:

Hot work performance was a focus item for the licensee as well as the resident inspectors in the last half of the year. The licensee has developed a procedure that is specifically for hot work, has conducted training, and provided extra oversight in the field. The licensee has improved performance although, the resident inspectors continued to note deficiencies in this area.

The residents and the site have identified a number of maintenance issues associated with the main cooling reservoir. Some of the issues include vegetation control in and around the reservoir, relief well washout, outfall piping elevation drop, and piezometer protection piping damaged. The licensee is having an assessment from an outside consultant to help prioritize and correct the issues. The resident inspectors toured the main cooling reservoir and do not currently have an operability concern.

The residents have noted several essential cooling water leaks (aluminum-bronze)which were shared with the licensee. The number of noted leaks and condition reports have not identified any trends as the licensee normally identifies 2-3 leaks per year and promptly corrects the issues by replacing the piping as necessary.

c. Findings

No findings were identified.

.3 Annual Follow-up of Selected Issues

a. Inspection Scope

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

On December 7, 2015, the inspectors reviewed a discrepancy between the emergency plan and the safety evaluation report.

The inspectors assessed the licensees 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 were adequate to bring the emergency plan back into compliance with the safety evaluation report.

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

b. Findings

Failure to Maintain the Emergency Plan

Introduction:

The inspectors identified a Green non-cited violation of 10 CFR 50.54(q)(2)for failure to maintain the emergency plan. Specifically, the licensee failed to meet 10 CFR 50.47(b)(2) requirements for timely augmentation of response capabilities, in accordance with the approved safety evaluation report.

Description:

During review of a license amendment request, dated October 6, 2015, regarding the site emergency plans staff augmentation response times, NRC staff noted a discrepancy between the current site emergency plan and the approved safety evaluation report. The licensee submitted an earlier license amendment request dated November 3, 1992, the purpose of which was to increase the ERO staff augmentation times by 15 minutes. This changed staff augmentation times from 45 minutes (for radiation protection technicians and nuclear engineers) and 60 minutes (for other staff)to 60 minutes and 75 minutes respectively. The license amendment request stated that these times were following an emergency declaration. Prior to this change, the licensees emergency plan and the NRCs safety evaluation report required the licensees staff augmentation time requirements to begin following an emergency notification, which the licensee was satisfied with. On May 20, 1993, the NRC approved the licensees request for extending ERO staff augmentation response times following emergency declaration, and issued an updated safety evaluation report containing this change on the same date. The licensee updated the emergency plan to reflect the new ERO staff augmentation response times, but failed to update the emergency plan with the change for ERO staff augmentation time requirements from notification to declaration. Table C-1 of Section C of the emergency plan incorrectly stated that time requirements for ERO staff augmentation are from the time of an emergency notification vice the time of an emergency declaration. Failing to implement this change could delay ERO staff augmentation times by as much as 15 minutes causing the licensee to exceed the time requirements set forth by the safety evaluation report.

The licensee has demonstrated through unannounced off-hours activation drills and announced staff drills that a loss of timely ERO staff augmentation would not have occurred as a result of the emergency plan change from time of notification to time of declaration. This issue was entered into the licensees corrective action program as Condition Report 15-23835. As part of their corrective actions, the licensee updated the emergency plan to accurately show that ERO staff augmentation times are to commence at the time of an emergency declaration.

Analysis:

Failure to maintain the site emergency plan in accordance with the approved safety evaluation report, dated May 20, 1993, was a performance deficiency.

Specifically, the licensee failed to update the ERO staff augmentation time requirements to commence at the time of an emergency declaration, as required by the NRC safety evaluation report. This performance deficiency is more than minor because it is associated with the procedure quality attribute of the Emergency Preparedness Cornerstone and adversely affected the cornerstone objective to ensure that the licensee is capable of implementing adequate measures to protect the health and safety of the public in the event of a radiological emergency. This finding was evaluated using Inspection Manual Chapter 0609, Appendix B, Emergency Preparedness Significance Determination Process (SDP), dated September 22, 2015, and was determined to be of very low safety significance (Green) per Table 5.2-1, Significance Examples 50.47(b)(2), because the staffing processes do not meet the threshold of routinely not capable of ensuring timely augmentation of the on shift emergency response staff to the extent that more than one required ERO functional area (in accordance with E-plan commitments) would not be filled. No cross-cutting aspect is assigned because the performance deficiency is not indicative of present performance.

Enforcement:

Title 10 CFR 50.54(q)(2) requires, in part, that a holder of a nuclear power reactor operating license shall follow and maintain in effect emergency plans which meet the requirements in Appendix E, part 50, and for nuclear power reactor licensees, the planning standards of 10 CFR 50.47(b). Title 10 CFR 50.47(b)(2) requires, in part, that timely augmentation of response capabilities is available. Contrary to the above, from May 20, 1993, until November 3, 2015, the licensee failed to ensure that timely augmentation of response capabilities was available. Specifically, a change to the safety evaluation report affecting the emergency plan was not appropriately implemented in that Table C-1 of Section C of the emergency plan was not updated to reflect ERO staff augmentation times are from the time of an emergency declaration vice the time of an emergency notification. The licensee restored compliance by revising the site emergency plan to require timely staff augmentation following an emergency declaration. The violation was entered into the licensees corrective action program as Condition Report 15-23835. Because the finding was of very low safety significance and has been entered into the licensees corrective action program, this violation is being treated as a non-cited violation consistent with Section 2.3.2.a of the NRC Enforcement Policy: (NCV 05000498/2015004-02; 05000499/2015004-02, Failure to Maintain the Emergency Plan Up to Date With the Safety Evaluation Report.)

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

Main article: IP 71153

.1 Event Follow-up for Excessive Leakage into a Waste Holding Tank

On November 13, 2015, while in Mode 3, following Refueling Outage 1RE19, Unit 1 experienced increased leakage into the chemical volume control system waste holding tank when a demineralizer was placed on service. Control room operators treated this excessive leakage as reactor coolant system leakage until the source of the leak could be identified and isolated. The licensee declared a Notice of Unusual Event (NOUE)based on Unidentified Reactor Coolant Boundary Leakage. Shortly after entering the NOUE Control room operators identified the leakage was coming from a chemical volume control system drain valve and isolated that valve. The inspectors responded to the control room and observed the licensees identification and resolution of the issue, including walking down the affected portion of the chemical and volume control system, reviewing operator logs, and interviewing operators. The licensee retracted the NOUE on December 08, 2015 because the source of the leak was from the chemical volume control system and not the reactor coolant system. Inspectors determined that the retraction was appropriate.

No findings were identified.

.2 Event Follow-up for Unit 1 Manual Turbine and Reactor Trip

On December 21, 2015, while Unit 1 was at 48 percent power, turbine governor valve 2 began to oscillate open and closed, resulting in large load swings and steam dump actuation. Operators began to reduce turbine load in order to stabilize the governor valve, but the oscillations continued. The shift manager directed a manual trip of the main turbine. Main turbine governor valve 2 continued to oscillate and the group one steam dumps failed to operate, as designed, to manage the main steam to the condenser on the turbine load reject. Main feedwater continued to fill the steam generators to the main feedwater isolation setpoint of 87.5 percent. All four steam generator power operated relief valves lifted as designed. Steam generator levels lowered, and with no ability to feed the steam generators to maintain levels, the shift manager ordered a manual reactor trip. All control rods fully inserted into the reactor core and all safety-related systems functioned as designed, with the exception of steam generator A blowdown containment isolation valve that failed to isolate on the main feedwater isolation.

The resident inspector responded to the control room upon hearing the load reduction plant announcement. The resident inspector observed all major evolutions and the operating crews performance, reviewed the licensees initial investigation and equipment repair prior to starting up the reactor. The inspectors also reviewed the initial licensee notification to verify it met the requirements specified in NUREG-1022, Event Reporting Guidelines, Revision 3.

No findings were identified.

These activities constitute completion of two event follow-up samples, as defined in Inspection Procedure 71153.
