(1) LER 05000255/2018-003-00 Indications Identified in Reactor Pressure Vessel Head Nozzle Penetrations. ADAMS Accession: ML19003A239 The circumstances surrounding this LER are documented in the Results Section of this Report

INSPECTION RESULTS

Observation: Semi-Annual Trend Review 71152 The inspectors review was focused on human performance issues, but also considered the results of daily inspector CAP item screening and licensee trending efforts. The inspectors review nominally considered the 6 month period of January 2019 through June 2019, although some examples expanded beyond those dates when warranted by the scope of the trend.

The inspectors reviewed condition reports, trend reports, and human performance evaluations to address performance oversight at the site. During the inspection period, the NRC inspectors noted a few challenges where low level human performance errors occurred in multiple departments, including Operations, Maintenance, and Projects. Examples included an inadvertent fuse disconnect during maintenance activities which resulted in an unanticipated momentary loss of the 1D DC distribution system during live-dead-live checks, component cooling water system miss-alignment to two control rod drive mechanism housings resulting in a 40F increase in housing temperatures, bumping open a Main Steam Isolation Valve Bypass Valve motor power supply breaker with a fire hose during a planned fired drill, and hanging a danger tag on the wrong drain valve on the plant heating boiler system and then not identifying the error until after maintenance had been completed.

Although the above examples did not challenge safety function or equipment reliability, these issues illustrated a decline in the use of human performance tools to prevent errors while performing work in the field and signs of complacency; all of which could potentially impact nuclear safety.

The licensee appropriately entered these issues into the CAP and completed timely evaluations of these issues to determine the causes of the performance decline. Corrective actions included training, site-wide communications reinforcing standards and expectations, and a re-emphasis on the following human performance tools: pre-job briefs; procedure use and adherence; and verification and validation activities. The inspectors determined that the corrective actions taken to date appeared to be effective at addressing the identified gaps and plan to continue to evaluate these actions during routine observations and inspections.

Observation: RPS Channel B Failure Resulting in an Automatic Reactor Trip 71152 On January 9, 2019, the licensee experienced an automatic reactor trip and valid actuation of the auxiliary feedwater (AFW) system. The direct cause of the event was identified to be a loss of all power to the reactor protection system (RPS) BD matrix due to shorted capacitors associated with the RPS B channel and a blown fuse association with the RPS D channel BD matrix power supply. The inspectors reviewed the licensee's final adverse cause analysis after a failure evaluation of the RPS D channel BD matrix power supply and fuse was conducted.

The inspectors reviewed the results of the failure evaluation and discussed these results with the licensee. Using the results of the failure evaluation, the licensee identified that the RPS D channel BD matrix power supply module was no longer meeting its efficiency rating and was a causal factor. Additional corrective actions from the failure evaluation included creation of a periodic maintenance activity to perform periodic thermography on the power supplies to identify potential vulnerabilities to similar failure modes. The inspectors determined that the corrective actions were appropriate and timely based on the safety significance of the issue.

Observation: Licensee Cause Determination - Missed Flaw Indications Identified 71152 in Reactor Pressure Vessel Head Nozzle Penetrations On November 10, 2018, with the plant in Mode 6, during bare metal visual inspections of the reactor vessel closure head (RVCH), dried boric acid was identified in the area of reactor head nozzle 25, indicative of a through-wall flaw. The licensees contractor had recently completed ultrasonic (UT) examinations of this nozzle and the inspectors inquired if the licensees contractor had identified flaw indications or evidence of leakage during this examination. The inspectors questions prompted the licensees contractor to re-review nozzle 25 UT data and the contractor staff subsequently identified an inside diameter (ID)connected flaw indication and UT indications of leakage within the annulus behind nozzle 25 (e.g. UT leak path). Subsequently, the contractor performed a re-review of all nozzle UT data and subsequently applied an eddy current (ET) technique to the ID surface of nozzles 34 and 36 and identified an additional two nozzles with ID flaw indications (nozzles 33 and 36).

The results of the licensee's 2018 RVCH UT examination were documented in report 180-9291875-000 Palisades Unit 1, 1RO26 Reactor Head Inspection Report and included the following information: penetration nozzle 25 had an inside diameter connected axial 100 percent through-wall flaw indication with a 1.4 inch length; penetration nozzle 33 contained an inside diameter connected axial part through-wall flaw indication with a 0.890 inch length; and penetration nozzle 36 had two inside diameter connected part through-wall off-axis flaws that were recorded as 0.514 inch and 0.729 inch in length respectively. As a corrective action, the licensee performed just-in-time training on the flaw characteristics observed in nozzles 25 and 33 and this training was applied to re-inspection of the remainder of the reactor head nozzle population to ensure all flawed nozzles were identified. The licensee repaired the affected nozzles 25, 33 and 36 utilizing the contractor's (Framatome) half-nozzle replacement method prior to returning the RVCH to service. On January 3, 2019, the licensee issued LER 2018-003-00 Indications Identified in Reactor Pressure Vessel Head Nozzle Penetrations and reported this in accordance with 50.73(a)(2)(ii)(A) as a condition of the nuclear power plant, including its principal safety barriers, being seriously degraded. Additional information on the event can be found in Section 71153 of this report.

The licensee documented an apparent cause evaluation (ACA) for boric acid found at control rod drive nozzle 25 in CR-PLP-2018-05857. In this ACA, the licensee identified two direct causes of the boric acid deposit found at control rod drive nozzle 25: Direct Cause 1 - the Palisades head nozzle material (Inconel Alloy 600) which is susceptible to primary water stress corrosion cracking (PWSCC), resulted in a through-wall flaw in nozzle 25, and Direct Cause 2 - the contractor examiners failure to resolve the ID surface initiated flaw in nozzle 25. Additionally, the licensee identified two causal factors: Causal Factor 1 - Flaws that initiate on the outside diameter are the primary area of focus during head penetration exams, resulting in the examiner failing to identify specific characteristics of ID initiated flaws. As a result, the ID initiated flaws were not identified and corrected prior to the through-wall flaw in

1R26 (a.k.a. - Palisades 2018 refueling outage); and Causal Factor 2 - ET was removed as

an examination technique and therefore, the ID initiated flaws were not resolved prior to developing a through-wall flaw in 1R26.

The inspectors reviewed the licensees cause investigation, extent of condition, and extent of cause for this event associated with the identification of degraded nozzles in the RVCH to ensure that the licensee identified the full extent of performance errors and had established actions to correct these errors. Additionally, the NRC Vendor Inspection Branch completed a review of the contractors root cause investigation and corrective actions for this event as this issue potentially impacted other licensees (reference NRC report 99901300/2019-201). The inspectors confirmed the licensee established an adequate basis for the Direct Causes 1 and 2 in the ACA completed under CR-PLP-2018-05857. However, Causal Factor 2 associated with the removal of the ET technique, did not have a sufficient basis for the inspectors to independently confirm this as a causal factor because both ET and UT are qualified to detect ID flaws. Specifically, the UT technique applied was demonstrated as qualified to detect ID flaws and ET was also qualified to detect ID flaws, so either method would be sufficient to detect PWSCC. Therefore, the inspectors could not substantiate Causal Factor 2 and considered this a weakness in the licensees ACA. Additionally, the scope of the licensees ACA was limited to planar flaws within the RVCH nozzles and did not include the contractors failure to identify evidence of a UT leak path signal at nozzle 25. The UT leak path method is relied on to identify flaws that may exist in the J-groove weld of a nozzle and which may not be detected by visual examinations looking for evidence of leakage on the RVCH. To address this issue, the licensees contractor assigned an action to correct this error during the 2018 outage (e.g. just in time training and procedure changes) and therefore the inspectors were not concerned that the narrow scope of the licensees ACA had adversely impacted the ability to detect the full extent of degraded RVCH nozzles and J-groove welds.

In response to the missed flaw indications, the licensee conducted a self-assessment of the programs for contractor oversight of the vessel head inspections. Specifically, in CR-HQN-2019-00577 Fleet NDE oversight of RVCH examinations the licensee identified causal factors and conclusions as they related to programs for oversight of the contractor head UT examinations. In this document, the licensee identified program weaknesses which included:

No governing standard existed for oversight of RVCH inspections; Fleet Inspection Services did not rigorously challenge the implementation of the contractor procedure requirements for two specific areas - pre-job briefings and UT data analyst independence, and no formal operating experience screening was performed for a similar missed flaw event that occurred in 2013 at the Shearon Harris Plant. The licensee concluded that had these insights been realized prior to the examinations, Entergy would have been less vulnerable to missed indications.

The inspectors reviewed the licensees self-assessment as documented in CR-HQN-2019-00577 and confirmed the licensee established an adequate basis for its program findings but noted that the licensee had not reviewed the Indian Point Unit 2 (IP2) nozzle leakage event which occurred within the prior 6 months of the Palisades head leak (reference IP2 licensee event report (LER) 05000-247- 2018-001-00, Penetration Indications Discovered During Reactor Pressure Vessel Head Inspection). The lack of a review of the IP2 event to gain insights on program performance indicated a narrow scope of review for related operating experience, in particular since the IP2 site is owned and operated by the Palisades licensee.

Minor Violation 71153 Minor Violation: On January 21, 2019, the licensee was informed by the reactor vessel closure head (RVCH) examination contractor of a Part 21 deviation in contracted services based on a vendor reanalysis of ultrasonic (UT) exam data completed in November of 2018 (reference Framatome CR 2018-9955). The contractor identified a Part 21 deviation from contracted services in RVCH examinations associated with the results the contractors re-review of UT data, for past outages. Specifically, an axially oriented flaw indication was present in the nozzle 25 material that had not been reported as a flaw indication during previous RVCH examinations. As of June 27, 2019, the licensee had not applied site procedure EN-LI-1008-01 10 CFR 21 Evaluations And Reporting in response to the contractors identification of a Part 21 deviation. Specifically, the licensee did not follow Section 5.2 of procedure EN-LI-1008-01 which stated If it is determined that the deficiency/condition does constitute 10 CFR 21 discovery of a Technical Specification Safety Limit related issue, deviation or failure to comply, then the Responsible Department Manager documents the bases of the determination and proceeds to Section 5.3. and Assign a corrective action to the Responsible Department Manager to complete Attachment 9.3 as soon as practicable, and in all cases within 60 calendar days of determining that the deficiency/condition does constitute discovery of a deviation or failure to comply (i.e., the determination of answers to Attachment 9.2). The licensees failure to follow procedure EN-LI-1008-01 and complete an evaluation of the contractor identified Part 21 deviation, represented a violation of 10 CFR Appendix B, Criterion V Instructions, Procedures, and Drawings, which 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.

Screening: The inspectors determined the performance deficiency was minor. For this issue, the licensees contractor completed a Part 21 evaluation and concluded that although this issue met the definition of a Part 21 deviation, the missed UT indication in nozzle 25 did not pose a substantial safety hazard or a risk of violating a safety limit (as defined in 10 CFR Part 21) associated with the integrity of the reactor coolant pressure boundary and was therefore not a defect as defined in Part 21. Based on substantial margins that existed until reaching a critical (e.g. unstable) crack size for nozzle 25 and the absence of corrosion induced wastage of the RVCH, the inspectors agreed with the licensees contractor assessment that this issue did not pose a substantial safety hazard. With this result, the inspectors applied the IMC 0612, Appendix B Issue Screening process and answered no to the more than minor questions for this violation because no loss of safety function occurred. Additionally, the inspectors considered this to be this similar to minor Example F of Section 4 Insignificant Procedural Errors of IMC 0612, Appendix E Examples of Minor Issues.

Enforcement:

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

Minor Violation 71153 Minor Violation: On November 10, 2018, with the plant in Mode 6, during bare metal visual inspections of the reactor vessel closure head, dried boric acid was identified in the area of reactor head nozzle 25, indicative of a through-wall flaw. On January 3, 2019, the licensee issued a licensee event report (LER) 2018-003-00 Indications Identified in Reactor Pressure Vessel Head Nozzle Penetrations and reported this in accordance with 10 CFR Part 50.73(a)(2)(ii)(A) as a condition of the nuclear power plant, including its principal safety barriers, being seriously degraded. However, the licensee did not perform an investigation to determine if the accumulation of a boric acid deposit at nozzle 25 was indicative of plant operation with through-wall pressure boundary leakage and as such was prohibited by Technical Specification (TS) LCO 3.4.13, which states that operational LEAKAGE shall be limited to: No pressure boundary LEAKAGE. The licensees failure to report plant operation prohibited by TS to the NRC in an LER represented a violation of 10 CFR Part 50.73(a)(2)(i)(B).

Screening: The inspectors determined the performance deficiency was minor. Consistent with the guidance in Inspection Manual Chapter (IMC) 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening, the inspectors determined the performance deficiency was not a finding of more than minor significance based on No answers to the more-than-minor screening questions. The inspectors also reviewed the examples of minor issues in IMC 0612, Appendix E, Examples of Minor Issues and found no examples related to this issue. Additionally, based on review of Section 2.2.2 Traditional Enforcement of the NRCs Enforcement Policy, this issue represents a minor violation because failure to make this report resulted in no appreciable potential safety consequence and was less significant than a SL IV violation.

Enforcement:

This failure to comply with Part 50.73(a)(2)(i)(B) constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.

Unresolved Item Qualification Basis for Safety-Related Agastat Relays and 71152 (Closed) Molded Case Circuit Breakers05000255/2013005-06

Description:

On February 12, 2014, the NRC issued Inspection Report 05000255/2013005 documenting Unresolved Item (URI)05000255/2013005-06. This URI was associated with safety-related molded case circuit breakers (MCCBs) and Agastat relays installed in mild environments which appeared to not have preventive maintenance (PM) schedules for inspection or replacement to address their specified lifetime. Since then, the NRC undertook efforts, such as training, to assist inspectors in dispositioning issues related to how long safety-related components remain in service and to clarify the applicability of various regulations and industry standards. As part of this effort, the NRC determined current agency regulations require the establishment of quality assurance programs and supporting procedures that, among other things, set PM schedules for the inspection or replacement of parts having a specific lifetime.

During the NRC's previous inspection, the inspectors determined the licensee had developed PM schedules and associated procedures for the inspection of the MCCBs. However, the appropriateness of the schedule and procedures to detect degradation prior to the MCCB experiencing a loss of safety function was not readily evident. While the NRC undertook the training efforts previously described, the licensee replaced the MCCBs installed beyond their specified life and created recurring work tasks to replace MCCBs prior to the breakers exceeding their specified life as documented in CR-PLP-2015-1914 and CR-PLP-2013-4010.

Because these actions reasonably ensured the continued quality of the MCCBs during their specified lifetime, the inspectors determined further efforts to evaluate the appropriateness of the procedures in effect at the time the URI was issued were no longer needed to provide reasonable assurance of adequate protection of public health and safety.

Regarding the Agastat relays, the inspectors determined the licensee had developed PM schedules and associated procedures to manage the service life of safety-related Agastat relays prior to the issuance of this URI. Specifically, on January 1, 2009, the licensee initiated corrective action document CR-PLP-2009-00346 to address a deficiency regarding their PM strategy for safety-related Agastat relays. The associated corrective actions included the development of EC20559, Validate Selective Agastat Relays Setpoint Data, Revision 0, which validated and/or established inspection acceptance criteria intended to detect degradation prior to loss of safety function. These acceptance criteria were included in calibration sheets which are implemented during periodic PM activities.

Based on the above, no performance deficiency or violation of regulatory requirements was identified. This review did not represent an inspection sample.

In particular, the licensees UT contractor mischaracterized flaw indications, and thus had not identified them as flaws before they resulted in operation with the pressure boundary LEAKAGE. The inspectors determined the condition was reasonably foreseeable and preventable by the licensee as there were several weaknesses in the licensees oversight of its contractor that mischaracterized the nozzle flaw indications.

Description:

On November 10, 2018, with the plant in Mode 6, during bare metal visual inspections of the RVCH, dried boric acid was identified in the area of nozzle 25, indicative of a primary coolant system (PCS) leakage from a through-wall flaw. The licensees contractor (Framatome) had recently completed UT examinations of nozzle 25 and the NRC inspectors inquired if the contractor had identified flaw indications or evidence of leakage during this UT examination. The inspectors questions prompted the licensees contractor to re-review nozzle 25 UT data and the contractor staff subsequently identified an inside diameter (ID)connected axial thru-wall flaw indication and UT indications of leakage within the annulus behind nozzle 25 (e.g. UT leak path). Subsequently, the contractor performed a re-review of all nozzle UT data and then applied an eddy current examination technique to the ID surface of nozzles 34, and 36 and identified additional ID connected flaws in nozzles 33 and 36. In licensee event report (LER) 2018-003-00, the licensee determined the cause of these flaws to be primary water stress corrosion cracking (PWSCC) based on the nozzle material (Inconel Alloy 600) which is known to be susceptible to PWSCC. Additionally, the licensee reported that the reactor head UT contractor performed an in-depth summary of the prior data reviews on reactor head nozzles 25, 33, and 36 and that the result of this review shows that the ID-initiated axial flaws were present and detectible with the demonstrated inspection method in 2007, 2009, 2010, and 2012. The licensees contractor staff had not observed ID initiated flaws since the 2001-2002 timeframe, and thus the UT examinations of the RVCH were focused on identification of outside diameter (OD) initiated flaws.

Each of the RVCH nozzle UT examinations dating back to 2007 were completed by the same contractor (Framatome) in accordance with procedure 54-ISI-604 Automated Ultrasonic Examination of Open Tube Reactor Pressure Vessel Closure Head Penetrations (Revisions 3 through 13) and this procedure was required to be qualified for detection of flaws in vessel head penetration nozzles in accordance with applicable NRC requirements (e.g. NRC Order EA 03-009 Establishing Interim Inspection Requirements for Reactor Pressure Vessel Heads at Pressurized Water Reactors, 10 CFR 50.55a Codes and Standards, Code Cases 729-1 and Code Case N-729-4). Procedure 54-ISI-604 included instructions for identification of ID connected flaws and the contractor staff that applied this procedure had demonstrated the capability to detect ID flaws with this procedure. Specifically, certification records (Performance Demonstration Qualification Records issued by the Electric Power Research Institute (EPRI)) existed for each of the contractor staff that performed inspections of nozzles 25, 33 and 36 confirming that the contractor staff member had demonstrated the ability to detect and size flaws that originated at both the ID and OD surface of mockup RVCH nozzles.

However, the procedure steps for classifying UT indications as ID flaws were not properly applied by the licensees contractor staff during each of the 7 times that the RVCH nozzles were examined from 2007 through 2018. As a result, the flaw indications present in nozzles 25, 33 and 36 were previously mischaracterized by the contractor staff and thus not identified as flaws.

Upon discovery of the through-wall leak on nozzle 25, the licensee determined that the leak was present for a maximum of the duration of operating cycle 26 and that refinement of that leakage duration was immaterial to cause investigation, corrective action determination, or repair plans. Therefore, the licensee did not conduct an evaluation to determine a more precise leakage duration. Based on the presence of a through-wall flaw in nozzle 25, in conjunction with a confirmed UT leak path signal, and dried boric acid deposit present at the outside vessel head surface at nozzle 25, the inspectors concluded leakage existed well in excess of 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> during operating cycle 26.

In response to the missed flaw indications, the licensee conducted a self-assessment of the programs for contractor oversight of the vessel head inspections. Specifically, in CR-HQN-2019-00577 Fleet NDE oversight of RVCH examinations the licensee identified causal factors and conclusions as they related to programs for oversight of the contractor head UT examinations. In this document, the licensee identified a number of program weaknesses which included: No governing standard existed for oversight of RVCH inspections; Fleet Inspection Services did not rigorously challenge the implementation of the contractor procedure requirements for two specific areas - pre-job briefings and UT data analyst independence, and no formal operating experience screening occurred for a similar 2013 missed flaw event that occurred at the Shearon Harris Plant. The licensee concluded that had these insights been realized prior to the RVCH examinations, Entergy would have been less vulnerable to missed indications. Therefore, the licensee missed opportunities to strengthen oversight of the Palisades UT examination process that could have precluded extended operation with a through-wall flaw at nozzle 25 as revealed during the 2018 Palisades outage (e.g. the leakage event at Palisades was reasonably foreseeable and preventable).

Corrective Actions: The licensees contractor staff completed training on the flaw characteristics observed in nozzles 25 and 33 and applied lessons learned from this training to the remainder of the reactor head nozzle population during the 2018 refueling outage to ensure all flawed nozzles were identified and the licensee repaired each of the flawed nozzles (25, 33 and 36) prior to returning the RVCH to service. The inspectors identified that the licensee had operated during cycle 26 with pressure boundary LEAKAGE which is prohibited by TS LCO 3.4.13 and the licensee entered this TS violation into the corrective action program for further corrective action.

Corrective Action References: CR-PLP-2019-02516

Performance Assessment:

Performance Deficiency: The licensees failure to change plant operating conditions from Mode 1 (Power Operation) to Mode 3 (Hot Standby) within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and Mode 5 (Cold Shutdown) within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />, with pressure boundary LEAKAGE at RVCH nozzle 25 during operating cycle 26 was contrary to TS LCO 3.4.13 and a performance deficiency. In particular, the licensees UT contractor mischaracterized flaw indications, and thus had not identified them as flaws before they resulted in operation with the pressure boundary LEAKAGE. The inspectors determined the condition was reasonably foreseeable and preventable by the licensee as there were several weaknesses in the licensees oversight of its contractor that mischaracterized the nozzle flaw indications.

Screening: The inspectors determined the performance deficiency was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, continued operation with pressure boundary LEAKAGE at RVCH nozzle 25 if not corrected, would result in wastage of the RVCH which would increase the chance for a loss-of-coolant (LOCA) event and rod ejection.

Significance: The inspectors assessed the significance of the finding using Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The inspectors screened the safety significance as Green using IMC 0609, Appendix A, Exhibit 1, LOCA Initiators, because, after a reasonable assessment of degradation, it was determined that the violation did not result in exceeding the PCS leak rate for a small-break LOCA and did not affect any other systems used to mitigate a LOCA that could result in a total loss of function. Although, the licensee's UT examination was not successful in identifying the flaw in nozzle 25 before minor leakage occurred, the licensees bare metal visual exam was successful in identifying the leakage condition, and the licensee's timely corrective actions prevented this condition from becoming a more safety significant concern. Therefore, the inspectors determined that the issue is of very low safety significance (Green).

Cross-Cutting Aspect: H.2 - Field Presence: Leaders are commonly seen in the work areas of the plant observing, coaching, and reinforcing standards and expectations. Deviations from standards and expectations are corrected promptly. Senior managers ensure supervisory and management oversight of work activities, including contractors and supplemental personnel. In this case, the licensee failed to establish adequate oversight of the contractor during UT examinations of RVCH nozzles which resulted in extended operation with an undetected flaw in nozzle 25 that progressed through-wall and caused pressure boundary LEAKAGE [Item H.2].

Enforcement:

Violation: TS LCO 3.4.13 requires in part, PCS operational LEAKAGE shall be limited to: a.

No pressure boundary LEAKAGE; with the reactor in Modes 1, 2 3 and 4.

TS LCO 3.4.13.b Action statements for Condition Pressure boundary LEAKAGE exists include: B.1 - Be in MODE 3 completion time - 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and B.2 - Be in MODE 5 completion time - 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Contrary to the above, since approximately May of 2017 thru October 13, 2018, with the plant in Mode 1 (Power Operation) and pressure boundary LEAKAGE present through a nonisolable fault in a PCS component (reactor vessel head penetration nozzle 25), the licensee failed to place the plant in Mode 3 (Hot Standby) within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and Mode 5 (Cold Shutdown) within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Enforcement Action: This violation is being treated as an non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

The disposition of this finding and associated violation closes URI: 05000255/2018004-01.
