b. Findings and Observations

No findings were identified.

Equipment Reliability In NRC Inspection Report 05000285/201500 2, the inspectors identified a continuing adverse trend in equipment reliability at Fort Calhoun Station. The inspectors reviewed equipment reliability challenges from 2014 and 2015 through completion of the refueling outage in June, 2015. These challenges resulted in equipment unavailability, unplanned technical specification entries, operator burdens, and in some cases, plant transients. Of more recent concern wer e a number of equipment reliability issues during the refueling outage that affected safety system availability and plant performance. The licensee took specific actions to correct the individual equipment performance issues during the observed timeframe.

In addition, the licensee conducted a start

-up challenge review of the events that occurred during the outage prior to plant start

-up. Finally, the licensee senior leadership team had implemented engineering department excellence plans, equipment reliability improvement activities with engineering in partnership with the maintenance and operating departments, focus ed on operating experience

, self-assessment activities and benchmarking, and utilized a plant health committee T op 10 list to improve critical system health.

Since that time, the licensee has continued to reduce backlogs in open operability determinations and temporary configuration changes. In addition, the licensee's plant health committee continues to focus on their Top 10 equipment list to resolve those critical items. The licensee engineering leadership team is also committed to the continuing improvement of the boric acid corrosion control and maintenance rule programs.

The inspectors monitored equipment reliability over the past two quarters. Although some improvement has been note d, such as the apparent resolution of air voids in the component cooling water system and a reduction in the number of long term operability evaluations, the inspectors continue to observe equipment reliability issues at Fort Calhoun Station. Examples include: control room air conditioning failures, continuing safety injection tank (SIT) check valve leakage requiring frequent SIT drain and refills, reactor coolant pump RC

-3A seal performance and vibration issues, and a pressurizer level charging pump control circuit failure. The inspectors have determined that additional monitoring of the licensee's progress in improving equipment reliability at the Fort Calhoun Station is warranted and will be evaluated with the results documented in the next semiannual trend review.

.3 Annual Follow

The inspectors selected one issue for an in

-depth follow

-up: On November 30, 2015, gas voiding in the component cooling water 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 were adequate to minimize the likelihood of voids developing in the component cooling water system.

These activities constitute completion of one annual follow

-up sample as defined in Inspection Procedure 71152.

b. Findings

No findings were identified.

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

b. Findings

No findings were identified.

0. "Inadequate Design of High Energy Line Break Barriers"

The licensee submitted this report after they discovered that an inadequate High Energy Line Break (HELB) barrier had not been reported when it was originally discovered on September 30, 2013. The degraded barrier has been repaired and this LER was issued to document the original unanalyzed condition. The inspectors considered the licensee's previous actions to repair the HELB barrier and the documentation of this issue in the LER to be adequate and appropriate. The failure to report this condition in a timely manner is considered a minor violation in accordance with Section 2.3.1 of the Enforcement Policy. This failure to comply with the 10 CFR 50.73 reporting requirements in a timely manner constitutes a minor violation that is not subject to enforcement action in accordance with the NRC's Enforcement Policy. Therefore, this LER is closed. Documents reviewed are listed in the attachments.

0. "Inoperable Auxiliary Feedwater System Due to Inadequate Procedure Change

" The licensee submitted this report after they discovered that a procedure momentarily cross-tied Main Feed water (MFW) with Auxiliary Feedwater (AFW) during system restoration steps. The failure to maintain qualified boundaries between these two systems resulted in the inoperability of the AFW system. The licensee causal analysis determined that procedure reviewers did not understand piping class separation requirements. To address this condition, the licensee conducted an extent of condition review and identified that additional AFW system procedures were affected. T hese AFW procedures were administratively restricted for use until they were subsequently revised to correct the lineups. No system procedures other than AFW were found to have similar cross connecting issues. In addition, the licensee has submitted a Training Request Form to address operators understanding of the operability impact of cross

-tying class and non

-class piping systems.

NRC inspectors reviewed the details of this condition including corrective action documents, procedure revisions, and training documentation. Based on a review of the condition, the inspectors determined that during the period that the MFW and AFW systems were cross

-tied that the licensee was in violation of Technical Specification 2.5(1) which requires two AFW trains to be operable when cold leg temperature is above 300F. This violation was identified by the licensee and is discussed in further detail in section

4OA7 of this report.

Therefore, this LER is closed. Documents are listed in the attachment.

.4 (Closed) Licensee Event Report (LER) 05000285/2015

00, "Containment Spray Inoperable due to Original Design Error" On April 16, 2015, during a refueling outage the licensee identified that because the original design of the plant failed to consider the thermal effects of a main steam line break or loss of coolant accident on containment spray piping, modifications were necessary to ensure the operability of the containment spray system during one of these postulated events. This condition existed because the original design of the plant did not account for the rise in the temperature of the dry containment spray piping inside containment. During a main steam line break or loss of coolant accident this piping would heat up more rapidly than piping that contains water and could reach temperatures of up to 290 degrees Fahrenheit. This rise in temperature would impose previously unaccounted for thermal stresses on the piping which in turn would transmit those stresses to the containment liner via certain pipe supports. The licensee corrected the problem by performing modifications to the containment spray pipe supports to ensure that stress limits would not be exceeded in the event of the aforementioned condition. The licensee also performed calculations and determined that prior to the modifications, if the postulated event were to occur, the containment spray piping and supports would have been able to deliver adequate flow despite exceeding ASME Section III Appendix F stress limits for one pipe support.

NRC inspectors reviewed the details of this condition including pertinent calculations, corrective action documents, procedures, and completed work documentation associated with the modifications to the containment spray pipe supports. Based on a review of the condition inspectors determined that during the period prior to the modifications of the containment spray supports the licensee was in violation of Technical Specification 2.4(1)a.iv which requires all piping associated with the containment spray pumps to be operable while the reactor is in operation. This violation was identified by the licensee and is discussed in further detail in section

4OA7 of this report.

Therefore, this LER is closed. Documents are listed in the attachment

. These activities constitute completion of five event follow

-up sample s, as defined in Inspection Procedure 71153.

OTHER ACTIVITIES

.1 Operation of an Independent Spent Fuel Storage Facility Installation (ISFSI) at Operating Plants (60855.1)

a. Operation of an ISFSI Inspection Scope A routine ISFSI inspection was conducted of the Fort Calhoun Station (FCS) ISFSI on September 21

-24, 2015, by Region IV Division of Nuclear Material Safety inspectors. The inspectors observed and evaluated select licensee loading, processing, and heavy load procedures associated with the licensee's ISFSI program. Inspectors performed a review of the dry fuel storage records for the casks loaded at the ISFSI to verify that the licensee had loaded fuel in accordance with the Technical Specifications (TS) for approved contents.

A document review of routine ISFSI activities since the last NRC ISFSI inspection (April 2013) was performed by the inspectors. The licensee had not loaded any new canisters since the last NRC routine ISFSI inspection.

The inspectors requested documentation related to maintenance of the fuel building cask handling crane. Documents were provided that demonstrated the fuel building cask handling crane was inspected on an annual basis in accordance with the American Society of Mechanical Engineers (ASME) B30.2 safety requirements.

The inspectors reviewed the r adiological conditions at the FCS ISFSI through a document review of the most recent radiological survey and three years of thermoluminescent dosimeter (TLD) monitoring data from around the ISFSI. A dry

-cask-loading supervisor and one radiation protection (RP) technician accompanied the NRC inspector s during a walk

-down of the ISFSI pad. A radiological survey was performed by one RP technician to record gamma exposure rates. The measurements taken by the RP technician and independently confirmed by the NRC inspector s were consistent with measurements recorded on the most recent ISFSI site survey. The radiological conditions in and around the ISFSI were as expected for the age, heat

-load, and number of casks currently loaded at the ISFSI. The inspectors reviewed Annual Radiological Environmental Operating Reports for the FCS site for the last three years. The reports documented the dose equivalent to any real individual located beyond the site controlled area had been well below the 10 CFR 72.104(a)(2) requirement of less than 25 mrem per year.

The NRC inspectors reviewed the Corrective Action Program (CAP) associated with the ISFSI. A list of condition reports issued since the last NRC inspection conducted in April 2013, was provided by the licensee for the cask handling crane and ISFSI operations.

Of the list of Condition Reports (CRs) provided relating to the ISFSI and the cask handling cranes, the inspectors selected 37 for further review. The CRs were related to a variety of issues. The condition reports reviewed were well documented and properly categorized based on the safety significance of the issue. The corrective actions taken were appropriate for the situations.

The inspectors reviewed the licensee's 10 CFR 72.48 screenings and evaluations for ISFSI program changes since the last NRC routine ISFSI inspection. Of the list of screenings provided by the licensee, the inspectors selected five for further review.

Fort Calhoun Station had not performed any full 72.48 evaluations since the last NRC ISFSI inspection. The inspectors determined that the licensee had adequately evaluated the screenings reviewed.

The inspectors performed an on-site review of the Quality Assurance (QA) audits and QA surveillance reports related to dry cask storage activities at the FCS ISFSI. The QA audit reports and surveillances resulted in several condition reports. The inspectors reviewed the corrective actions resulting from the CRs to ensure that the identified deficiencies were properly categorized based on its safety significance and were properly resolved.

b. Findings

Adequate Analysis that Documents Protection of the ISFSI from Fires and Explosions Introduction

. The inspectors identified an unresolved issue associated with the licensee's ISFSI Fire and Explosion Hazard

Analysis.

Federal Regulations 10 CFR 72.212(b)(3) required general licensees to ensure that each cask used conforms to the terms, conditions, and specifications of the Certificate of Compliance. During a review of FCS Updated Fire Hazards Analysis (UFHA) EA97

-001 Appendix D "ISFSI Fire and Explosion Hazards Review," further information was required to determine if FCS was in compliance with the analysis.

Description

. The FCS UFHA EA97

-001 Appendix D was dated March 28, 2006. Section 3.3.2 of the Appendix documented that the analysis was based on a walk

-down of the station that took place in June of 2005. Many examples were found during the review of the UFHA such that the NRC was unable to substantiate whether or not the licensee's analysis bounded the current operations and site configuration around the ISFSI.

Many referenced analyses and sections in the UFHA referred to use of the light

-weight transfer cask and not the heavier OS197 Transfer Cask that is currently used by the licensee. A walk down of the storage yard to the south of the ISFSI identified a few office trailers and other miscellaneous combustible equipment that was not discussed in the UFHA. In 2007, Engineering Change 29295 replaced the main transformer. It was undetermined if this transformer was the same transformer that was analyzed in Section 3.3.2 of the ISFSI Fire and Explosion Hazards Review.

The licensee's review of this issue will be tracked as an Unresolved Item (URI) until the NRC is provided sufficient information to determine if ISFSI operations are bounded by the site's UFHA. (URI 07200054/5015004

-01, "Adequate Analysis that Documents Protection of the ISFSI from Fires and Explosions

").

4OA6 Meetings, Including Exit

On September 24, 2015

, the inspectors debriefed Mr. S. Dean, Plant Manager, and other members of the licensee's staff of the results of the ISFSI inspection documented in Section 4OA5.

On October 23, 2015, and after the Regional staff received consultation from NRC Headquarters Division of Spent Fuel Management's Spent Fuel Licensing Branch, regarding the Licensee identified violation discussed in Section 4OA7.1, the inspectors conducted a telephonic exit with Mr. S. Dean, Plant Manager, and other staff members. The inspectors presented the inspection results to members of the licensee management and staff. Licensee personnel acknowledged the information presented. The inspectors asked the licensee whether any materials examined during the inspection should be considered propriety. No propriety information was identified.

On November 19, 2015, the inspectors presented the inspection results to Mr. L. Cortopassi, Site Vice President, and other members of the licensee staff. The licensee acknowledged the issues presented. The licensee confirmed that any proprietary information reviewed by the inspectors had been returned or destroyed.

On December 9, 2015, the inspector s obtained the final annual cycle results and exited with Mr. B. Blessie, Operator Training Instructor. The inspector s did not review any proprietary information during this inspection.

On January 7, 2016, the inspectors presented the inspection results to Mr. L. Cortopassi, Site Vice President, and other members of the licensee staff. The licensee acknowledged the issues presented. The licensee confirmed that any proprietary information reviewed by the inspectors had been returned or destroyed.

4OA7 Licensee-Identified Violations

The following violation s of very low safety significance (Green) were identified by the licensee and were violation s of NRC requirements which meet the criteria of the NRC Enforcement Policy for being dispositioned as non-cited violations.

.1 Title 10 CFR 72.174 requires that each licensee maintain sufficient records to furnish evidence of activities affecting quality.

Records pertaining to the design, fabrication, erection, testing, maintenance, and use of structures, systems, and components important to safety must be maintained by or under the control of the licensee until the NRC terminates the license. Contrary to the above, as of June 21, 2013, Fort Calhoun failed to maintain sufficient records to furnish evidence of activities affecting quality. Specifically, the licensee did not maintain records for loading activities associated with DFS

-HSM-06 that was placed on the ISFSI pad in July of 2009. This violation was identified by FC S and placed in their corrective action program (CR 2013

-12884). The fuel assembly data was reconstituted based on records from the Reactor Engineering group

, and the canister helium leak

-test data was reconstituted based on the helium leak

-test technician's field notes. The remaining canister records associated with the canister processing, sealing, and transpor tation to the ISFSI, including several TS requirements, were not found. Fort Calhoun reconstituted the fuel and helium leak test data and conducted interviews with cask loading personnel to conclude that there was no evidence to suggest that loading activities did not comply with the licensee's procedures and the licensed Technical Specifications. This violation did not have any safety impact because all fuel assemblies met the requirements for burn

-up, decay heat, and cooling time and the licensee demonstrated that the canister integrity was intact based on the reconstituted helium leak test records. All the fuel inside the canister and the cask remain in a safe condition. This finding was reviewed by NRC Headquarters Division of Spent Fuel Management's Spent Fuel Licensing Branch. Based on the reconstituted records and interviews with the dry fuel loading staff, the NRC found no evidence to demonstrate that the canister did not meet the required license conditions and as such, found the canister acceptable for continued storage under FCS's general Part 72 license. However, though the canister is acceptable for storage, the licensee must track this issue to identify that further analyses may be required for this canister to meet all applicable Part 71 requirements to be acceptable for transportation.

In accordance with the NRC Enforcement Policy Section 2.2 and IMC 0612 Section 03.23, Part 72 ISFSI inspection findings follow the traditional enforcement process and are not disposition ed through the Reactor Oversight Process or the Significance Determination Process. The violation screened as having very low safety significance, Severity Level IV, and is being treated as a non

-cited violation, consistent with Section 2.3.2.a. of the Enforcement Policy.

The violation was determined to be more than minor since the licensee failed to establish, maintain, or implement adequate controls over procurement, construction, examination, or testing processes that are important to safety. The violation was entered into the licensee's corrective action program as CR 2013-12884. Following identification of the issue the licensee performed an assessment that showed the cask would continue to perform its design function. Corrective actions for this issue included performing an extent of condition review, performing an apparent cause analysis report, reconstitution of the missing documents, conducting interviews with the dry cask loading personnel, providing training to the staff involved, and changing processes and responsibilities within FCS Records Management Group.

.2 Technical Specification (TS)

2.4(1)a.iv requires that all valves, piping, and interlocks associated with the components of the containment cooling system required to function during accident conditions be operable

. In the event that any of these components

, required to function during accident conditions become inoperable, the reactor shall be placed in a hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The containment spray pumps and the associated piping are part of the containment cooling system. Prior to making modifications to containment spray piping in 2015, the operability of this piping would have been challenged by a main steam line break or a loss of coolant accident due to thermal stresses induced in the piping after a rise in containment temperature after the postulated event. Operation prior to the implementation of the modifications was a violation of the technical specification requirements to maintain operability of containment cooling systems.

The violation is more than minor because it is associated with the design control attribute of the mitigating systems cornerstone because the failure to anticipate the rise in containment spray piping temperature dates back to the original design of the plant. This adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The violation was of very low safety significance because although the subject piping was inoperable due to exceeding code specified stress limits, analysis showed that the piping would have been able to perform its safety function to deliver adequate containment spray flow in the event of an accident. The licensee entered the issue into their corrective action program as Condition Report 2015-04578.

.3 Technical Specification (TS)

2.5(1) requires two trains of auxiliary feedwater (AFW) to be operable when cold leg temperature is above 300F. In the event that both trains become inoperable, immediate action is required to restore one AFW train to operable status. Technical Specification 2.0.1 and all TS actions requiring mode changes are suspended until one AFW train is restored to operable status. Operation with the main and auxiliary feedwater cross-tied was a violation of the technical specification requirements to maintain operability of AFW systems. The violation is more than minor because it is associated with the configuration control attribute of the mitigating systems cornerstone because the failure to prevent cross

-tying these systems resulted in unrecognized inoperability of both trains of AFW. This adversely affects the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The violation was of very low safety significance because although MFW and AFW were momentarily cross

-tied, this condition existed for only a brief period of time as operators restored system line

-ups following system testing

. In addition, a Senior Reactor Analyst evaluated the postulated main feedwater line break frequency and exposure time of the condition and determined the likelihood of this event during the exposure time is less than the Green/White threshold and of very low safety significance. The licensee entered the issue into their corrective action program as Condition Report 2015 03698.
