71114.01 - Exercise Evaluation

The inspectors evaluated the conduct of the biennial emergency plan exercise during the week of October 1, 2018. The exercise scenario simulated a steam generator tube leak and eventual rupture, followed by a trip of a reactor coolant pump that produced foreign material that entered the reactor core area and caused fuel damage. Then a main steam line inside containment ruptured and caused containment pressure to rise. With less than one full train of containment spray available, a Site Area Emergency was declared. As containment radiation levels continued to rise, and with no means of decreasing containment pressure, a General Emergency was declared, followed by an eventual breach of containment for a release to the environment, thereby allowing the Offsite Response Organizations to demonstrate their ability to implement emergency actions.

INSPECTION RESULTS

Minor Violation

71152 - Annual Follow-up

of Selected Items Minor Violation: On October 2, 2018, the licensee discovered that surveillance requirement (SR) 3.3.2.4, Channel Operational Test, was not being performed for some instruments at the appropriate interval required by the surveillance frequency control program (SFCP). The licensee determined that the test intervals were inadvertently changed during the improved technical specifications (ITS) conversion project in 2015. 10 CFR Part 50, Appendix B, Criterion III, Design Control, requires in part that applicable regulatory requirements and the design basis are correctly translated into technical specifications, drawings, procedures, and instructions. The failure to translate the licensing basis requirement to perform SR 3.3.2.4 as required by the SFCP into the surveillance implementing procedures was a performance deficiency.

Screening: This performance deficiency was determined to be minor because the licensee was able to confirm operability of the affected instruments through successful completion of the missed surveillance activities. The issue did not result in any adverse consequences or loss of safety function.

Enforcement:

The failure to comply with 10 CFR Part 50, Appendix B, Criterion III constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.

Observation

71152 - Annual Follow-up

of Selected Items The inspectors conducted a detailed review of CR 1452772, Surveillances not performed per SR 3.3.2.4. This sample was selected due to the safety significance of the components involved. Specifically, SQN Unit 1 and Unit 2 channel operational tests for SG level, RWST level, and containment sump level instrumentation were not being implemented in accordance with the SFCP, which specified a performance frequency of 92 days. The frequencies of the surveillance implementing procedures were inadvertently changed to a 184 day frequency during the ITS conversion project in 2015.

When the condition was identified on October 2, 2018, the licensee invoked SR 3.0.3, and performed the required risk assessment to delay the requirement to declare the LCO not met up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the limit of the required frequency. The inspectors noted that there were a total of 24 surveillance instructions that were inadvertently changed during the ITS conversion, but only seven of those had not been performed within the required test interval of 92 days (plus 25% grace). The inspectors reviewed the licensees risk evaluation, which concluded that there was no significant increase in risk due to the missed surveillances and, therefore, acceptable to delay the performance an additional surveillance interval of 92 days (by January 2, 2019). The inspectors verified that the licensee successfully completed the missed surveillances by October 3, 2018, well before the end of the additional 92 day period.

The inspectors also reviewed the licensees extent of condition review and concluded that reasonable corrective actions had been taken to correct the condition. The licensees corrective actions are documented in CR 1452772 and included actions to re-baseline all 24 affected surveillances to the required 92-day frequency and perform a 10% random sampling of other SRs on a 184-day frequency to ensure they were at the proper frequency. The inspectors documented one minor violation associated with this issue.

Failure to Adequately Document the Basis for a Change to an Emergency Plan Implementing Procedure Cornerstone Severity Cross-Cutting Report Aspect Section Not Applicable Severity Level IV (SL-IV) Not Applicable

71114.04 - Non-Cited Violation (NCV) Emergency

05000327,328/2018004-01 Action Level Closed and Emergency Plan Changes The inspectors identified a SL-IV NCV of Title 10 of the Code of Federal Regulations (CFR),

Part 50.54(q)(3), for changes made to the Sequoyah Nuclear Plant Radiological Emergency Plan (E-Plan), and associated implementing procedures, that failed to demonstrate the changes would not reduce the effectiveness of the E-Plan. Specifically, the licensee did not provide an adequate analysis to determine whether the removal and addition of clarifying information was not a reduction in effectiveness (RIE) of the emergency action level (EAL)implementing procedure.

Description:

The licensee implemented a revised E-Plan and new EAL scheme in early 2018 that had been approved by the NRC. Prior to implementation of the NRC-approved E-Plan, the licensee identified many changes they wanted to make before issuing the revision to the EAL implementing procedure. The inspectors performed a detailed review of the changes to EAL implementing procedure EPIP-1, Emergency Plan Classification Matrix. The inspectors identified multiple occurrences of specific or clarifying wording that was either removed or added as part of this revision. An example of a specific clarification provided in the document that was removed was the following: if an EAL for a higher classification was exceeded, but the present situation indicates a lower classification, the fact that the higher classification occurred shall be reported to the NRC and Central Emergency Control Center (CECC), but should not be declared. Removal of this information from the document would be considered a RIE if it resulted in members of the Emergency Response Organization (ERO) no longer understanding or being unable to perform what the phrase dictated as their responsibility.

Also, if by removing a paragraph that provided specific definitions for indications, reporting, or conditions, as it is related to supporting timely classifications or declarations of emergencies, it would be considered a RIE if, as a result, members of the ERO took delayed actions.

Lastly, the inspectors found that a note added to the fission product barrier matrix flow chart bases that read: Multiple events could occur which result in the conclusion that exceeding the loss or potential loss thresholds is IMMINENT. In IMMINENT loss situations use judgement and classify as if the thresholds are exceeded. This addition would be considered a RIE if, as a result, members of the ERO were affected by the change such that it caused a delay in taking appropriate action. The inspectors found in the 50.54(q) change documentation, that the licensee categorized these changes as editorial in nature. By categorizing the changes as editorial, an analysis to determine whether the changes were a RIE of the EAL implementing procedure was not conducted. The inspectors determined that these changes were more than editorial and required an analysis be performed to justify whether the changes could provide the necessary and clarifying information to ensure that delayed actions would not occur.

Corrective Action(s): The licensee entered the issue into the corrective action program and on October 25, 2018, revised the 10 CFR 50.54(q) analysis for EPIP-1.

Corrective Action Reference: CR 1453687

Performance Assessment:

The licensees failure to provide an analysis demonstrating that changes to the EAL implementing procedure was not a reduction in effectiveness was determined to impede the NRCs ability to perform its regulatory function and is dispositioned using the Traditional Enforcement process.

Enforcement:

Severity: This finding is a violation of NRC requirements because it had the potential for impacting the NRCs ability to perform its regulatory function. Therefore, traditional enforcement is applicable, in accordance with Inspection Manual Chapter 0611 and 0612, Appendix B, Figure 2. This finding is determined to be a SL-IV violation in accordance with Section 6.6.d.1 of the Enforcement Policy because it involves the licensees ability to meet or implement a regulatory requirement not related to assessment or notification such that the effectiveness of the emergency plan is reduced.

Violation: Title 10 of the Code of Federal Regulations, Part 50.54(q)(3) states, in part, that a licensee may make changes to its emergency plan without NRC approval only if the licensee performs and retains an analysis demonstrating that the changes do not reduce the effectiveness of the plan and the plan, as changed, continues to meet the requirements in Appendix E to this part.

Contrary to the above, from July 3, 2018, through October 25, 2018, the licensee failed to perform an analysis demonstrating that changes to their E-Plan, and associated implementing procedures, did not reduce the effectiveness of the plan. Specifically, the licensee did not provide an analysis to determine whether the addition and removal of specific and clarifying words, as identified in the noted examples above, would not hinder or delay ERO actions, and result in a reduction in effectiveness of the approved Sequoyah E-Plan and associated EALs.

Disposition: This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy.

Introduction:

A self-revealed, Green, NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified on July 22, 2018, when the licensee failed to follow Section 3.2.2.A.1 of quality related procedure NPG-SPP-06.3, Pre-/Post-Maintenance Testing, in developing PMTs for PM 801560044, Replacement of a flow switch electronic circuit board associated with the B-train EGTS Air Cleanup Subsystem.

Description:

On June 26, 2018, at 0902 eastern daylight time, a flow switch electronic circuit board associated with the B-train EGTS Air Cleanup Subsystem relative humidity heaters was replaced due to the circuit board approaching the end of its environmentally qualified life.

Following board replacement, the flow switch was calibrated and the B-train of EGTS was returned to service in the standby condition. The post maintenance testing (PMT) did not require or recommend operability testing.

On July 22, 2018, Operations personnel performed a surveillance instruction for Surveillance Requirement (SR) 3.6.10.1 and identified that the B-train relative humidity heaters did not energize as required by the SR. Operators declared Limiting Condition for Operation 3.6.10, EGTS Air Cleanup Subsystem, not met and entered Condition A for one EGTS Air Cleanup Subsystem train being inoperable. On July 23, 2018, the flow switch circuit board for the B-train EGTS relative humidity heaters that had previously been removed on June 26, 2018, was reinstalled. Following reinstallation of the board, the B-train of EGTS was able to meet SR 3.6.10.1 and was declared operable July 24, 2018, at 0115.

A past operability evaluation (POE) was completed by the licensee and they determined that the B-train of the EGTS Air Cleanup Subsystem had been inoperable from June 26, 2018, at 0902 until July 24, 2018 at 0115. TS 3.6.10, Condition A allows 7 days to restore one train of the EGTS Air Cleanup Subsystem to operable status. TS 3.6.10 Condition B requires the unit to be in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> if the Required Action and associated Completion Time for Condition A are not met. Because one train of the EGTS Air Cleanup Subsystem was inoperable for greater than 174 hours0.00201 days <br />0.0483 hours <br />2.876984e-4 weeks <br />6.6207e-5 months <br /> (7 days plus 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) without entering Mode 3, this event was reportable in accordance with 10 CFR 50. 73(a)(2)(i)(B) as any operation or condition which was prohibited by the plant's Technical Specifications (TSs).

The inspectors reviewed the licensees LER and Corrective Actions associated with the event and determined they were adequate.

Corrective Actions:

The licensee determined that the cause of the event was the lack of formality in determining PMTs and return to operability (RTO) tests even though the procedure NPG-SPP-06.3, Pre-

/Post-Maintenance Testing, Section 3.2.2, Determining PMT Requirements, provides adequate guidance for this determination. The licensee identified the following corrective actions:

(1) To conduct information sharing with each Operations Crew and the Work Planners to determine PMT and RTO requirements in accordance with the maintenance procedure; and

(2) Update the preventive maintenance instructions associated with the work order for replacing a flow switch electronic circuit board on the EGTS Air Cleanup Subsystem.

Corrective Action References: CR 1433166 and 1436225

Performance Assessment:

Performance Deficiency:

Failure to follow quality related procedure NPG-SPP-06.3, Pre-/Post-Maintenance Testing, Section 3.2.2 in developing PMTs for PM 801560044, Replacement of a flow switch electronic circuit board associated with the B-train EGTS Air Cleanup Subsystem was a performance deficiency (PD). Specifically, on June 26, 2018, PM 801560044 was implemented but an adequate PMT was not performed, nor included in the PM package, to assure that all Operability and surveillance requirements had been satisfied as required by procedure NPG-SPP-06.3, Pre-/Post-Maintenance Testing.

Screening:

This PD was associated with the maintenance procedure quality attribute of the barrier integrity cornerstone and adversely affected the cornerstone objective to provide reasonable assurance that physical design barriers, such as containment systems, protect the public from radionuclide releases caused by accidents or events. Specifically, failure to perform an adequate PMT on the B-train EGTS system prior to returning it to service led to the licensee exceeding the allowable TS LCO action completion time and the inoperability of the B-train EGTS. The EGTS Air Cleanup subsystem, which is considered a containment system, reduces the radioactive content in the shield building atmosphere following a Design Basis Accident (DBA). A loss of this system could cause site boundary doses, in the event of a DBA, to exceed the values given in the licensing basis for the site.

Significance:

This performance deficiency was associated with the barrier integrity cornerstone. The inspectors screened this finding using IMC 0609, Appendix A, The Significant Determination Process (SDP) For Findings At-Power, dated June 19, 2012. Because both questions in Section B, Reactor Containment, of Exhibit 3, Barrier Integrity Screening Questions, were answered no, the finding screened as Green.

Cross-cutting Aspect:

The inspectors determined that the finding has a cross-cutting aspect of work management in the human performance area because the failure of the licensee to perform an adequate PMT, as required by procedure NPG-SPP-06.3, Pre-/Post-Maintenance Testing, did not ensure that nuclear safety was maintained (i.e. TS equipment shall be operable, but can be removed from service as long as its within the allowed action times). (H.5)

Enforcement:

Violation: 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, states, 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, prior to July 22, 2018, the licensee did not accomplish activities affecting quality in accordance with prescribed procedures. Specifically, NPG-SPP-06.3, Pre-

/Post-Maintenance Testing, is a quality related procedure and section 3.2.2.A.1 requires that PMTs shall be sufficiently comprehensive to ensure that that the maintenance performed does not adversely affect the equipments ability to perform its intended function. The licensee did not follow this procedure when developing PMTs for PM 801560044, Replacement of a flow switch electronic circuit board associated with the B-train EGTS Air Cleanup Subsystem Disposition: This violation is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy
