SUMMARY

IR 05000285/2016008; 07/25/2016 - 08/11/2016; Fort Calhoun Station; Evaluations of

Changes, Tests, and Experiments and Permanent Plant Modifications.

This report covers a two-week announced baseline inspection on evaluations of changes, tests, and experiments and permanent plant modifications. The inspection was conducted by Region IV based engineering inspectors. One finding was identified by the inspectors. The finding was considered a non-cited violation (NCV) of NRC regulations. The significance of most findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red)using Inspection Manual Chapter 0609, Significance Determination Process (SDP).

Cross-cutting aspects were determined using Inspection Manual Chapter 0310, Aspects Within the Cross-Cutting Areas. Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated July 9, 2013. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 6, dated August 2016.

NRC-Identified Findings

and Self-Revealed Findings

Cornerstone: Mitigating Systems

Section (c)(1), which states, in part, that a licensee may make changes in the facility as described in the final safety analysis report (as updated) without obtaining a license amendment pursuant to 10 CFR 50.90 only if: (i) a change to the technical specifications incorporated in the license is not required, and (ii) the change, test, or experiment does not meet any of the criteria in paragraph (c)(2). Title 10 CFR 50.59,

Section (c)(2), states, in part, that a licensee shall obtain a license amendment pursuant to Section 50.90 prior to implementing a proposed change, test, or experiment if the change, test, or experiment would result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the final safety analysis report (as updated). Specifically, from June 9, 2015 through August 11, 2016, the licensee implemented a change to Operating Instruction OI-VA-2, Auxiliary Building Ventilation System Normal Operation, Attachment 11, Revision 47, after incorrectly concluding that the opening of certain high-energy line break barriers and selected fire barrier doors to allow supplemental cooling of both safety-related switchgear rooms did not increase the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the final safety analysis report. In response to this issue, the licensee revised entry conditions to Operating Instruction OI-VA-2, Attachment II, to ensure that high energy line break barriers are not impaired prematurely. This finding was entered into the licensees corrective action program as Condition Report CR-2016-06667.

The licensees failure to implement the requirements of 10 CFR 50.59 and adequately evaluate the disabling of certain high-energy line break barriers to facilitate supplemental cooling of both safety-related switchgear rooms was a performance deficiency. This finding was evaluated using traditional enforcement because it had the potential for impacting the NRCs ability to perform its regulatory function. In accordance with Section 2.1.3.E.6 of the NRC Enforcement Manual, the inspectors used Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process For Findings At-Power, dated June 19, 2012, to determine that this performance deficiency was of very low safety significance (Green) because it (1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component and did not result in a loss of operability or functionality; (2) did not represent a loss of system and/or function; (3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than its technical specification allowed outage time; and (4) did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety significance in accordance with the licensees maintenance rule program. Therefore, in accordance with Section 6.1.d.2 of the NRC Enforcement Policy, the inspectors characterized this performance deficiency as a Severity Level IV violation. As described in Inspection Manual Chapter 0612, Power Reactor Inspection Reports, no cross-cutting aspect was assigned to this violation because traditional enforcement violations are not assessed for cross-cutting aspects.

1R17 Evaluations of Changes, Tests, and Experiments and Permanent Plant

Modifications (71111.17T)

.1 Evaluations of Changes, Tests, and Experiments

a. Inspection Scope

The inspectors reviewed 10 evaluations performed pursuant to Title 10, Code of Federal Regulations (CFR), Part 50, Section 59, to determine whether the evaluations were adequate and that prior NRC approval was obtained as appropriate. The inspectors also reviewed 21 screenings, where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The inspectors reviewed these documents to determine if:

  • the changes, tests, and experiments performed were evaluated in accordance with 10 CFR 50.59 and that sufficient documentation existed to confirm that a license amendment was not required;
  • the safety issue requiring the change, tests and experiment was resolved;
  • the licensee conclusions for evaluations of changes, tests, and experiments were correct and consistent with 10 CFR 50.59; and
  • the design and licensing basis documentation was updated to reflect the change.

The inspectors used, in part, Nuclear Energy Institute (NEI) 96-07, Guidelines for 10 CFR 50.59 Implementation, Revision 1, to determine acceptability of the completed evaluations and screenings. The NEI document was endorsed by the NRC in Regulatory Guide 1.187, Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments, dated November 2000. The list of evaluations, screenings, and/or applicability determinations reviewed by the inspectors is included as an to this report.

This inspection constituted 10 samples of evaluations and 21 samples of screenings and/or applicability determinations as defined in Inspection Procedure 71111.17-04.

b. Findings

Failure to Obtain Prior NRC Approval for a Change When Required

Introduction.

The inspectors identified a Severity Level IV, Green non-cited violation of 10 CFR 50.59, Changes, Test, and Experiments, associated with the licensees failure to adequately evaluate a change in order to ensure that they did not require prior NRC review and approval.

Description.

During review of 10 CFR 50.59 Evaluation 15-110, Revision 0, associated with Engineering Change (EC) 65749, Update Procedure, Calc, for Switchgear Supplemental Cooling, Revision 0, the inspectors noted that the licensee had changed Operating Instruction OI-VA-2, Auxiliary Building Ventilation System Normal Operation, 11, Revision 47, to allow the opening of certain high-energy line break barriers and selected fire barrier doors to provide supplemental cooling to both safety-related switchgear rooms. As documented in EC 65749, Revision 0, the switchgear rooms contain the electrical system normal and safety-related components (e.g., 4160V buses, 480V buses, inverters, and breakers that feed power to normal power production equipment and all safety-related equipment required by Technical Specifications). The inspectors also noted that the associated 10 CFR 50.59 review concluded that NRC prior approval was not required based on the evaluation of the proposed changes to Station Procedure OI-VA-2 against the eight 10 CFR 50.59 evaluation form questions.

Specifically, the licensee had answered question

.2 (Does the proposed activity result in

more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the USAR?)

in the negative, despite the introduction of a new failure mode for the affected safety-related switchgear components to be damaged as a result of a postulated high-energy line break. The new failure mode would damage both trains of safety-related switchgear, which would reduce electrical redundancy to mitigate the effects of a postulated high-energy line break.

The inspectors determined that the licensees conclusion was incorrect, in that, this change resulted in a more than minimal increase in the likelihood of the occurrence of a malfunction of a structure, system, or component important to safety that had been previously evaluated. The inspectors informed the licensee of their concerns, and the licensee initiated Condition Report CR-2016-06667 to document this issue in the stations corrective action program.

Analysis.

The licensees failure to implement the requirements of 10 CFR 50.59 and adequately evaluate the disabling of certain high-energy line break barriers to facilitate supplemental cooling of both safety-related switchgear rooms was a performance deficiency. This finding was evaluated using traditional enforcement because it had the potential for impacting the NRCs ability to perform its regulatory function. In accordance with Section 2.1.3.E.6 of the NRC Enforcement Manual, the inspectors used Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process For Findings At-Power, dated June 19, 2012, to determine that this performance deficiency was of very low safety significance (Green) because it

(1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component and did not result in a loss of operability or functionality;
(2) did not represent a loss of system and/or function;
(3) did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time, or two separate safety systems out-of-service for longer than its technical specification allowed outage time; and
(4) did not represent an actual loss of function of one or more non-technical specification trains of equipment designated as high safety significance in accordance with the licensees maintenance rule program.

Therefore, in accordance with Section 6.1.d.2 of the NRC Enforcement Policy, the inspectors characterized this performance deficiency as a Severity Level IV violation.

As described in Inspection Manual Chapter 0612, Power Reactor Inspection Reports, no cross-cutting aspect was assigned to this violation because traditional enforcement violations are not assessed for cross-cutting aspects.

Enforcement.

The inspectors identified a Severity Level IV, Green, non-cited violation of 10 CFR 50.59, Changes, Tests, and Experiments, Section (c)(1), which states, in part, that a licensee may make changes in the facility as described in the final safety analysis report (as updated) without obtaining a license amendment pursuant to 10 CFR 50.90 only if:

(i) a change to the technical specifications incorporated in the license is not required, and
(ii) the change, test, or experiment does not meet any of the criteria in paragraph (c)(2). Title 10 CFR 50.59, Section (c)(2), states, in part, that a licensee shall obtain a license amendment pursuant to Section 50.90 prior to implementing a proposed change, test, or experiment if the change, test, or experiment would result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the final safety analysis report (as updated). Contrary to the above, from June 9, 2015 through August 11, 2016, the licensee failed to obtain a license amendment pursuant to Section 50.90 prior to implementing a proposed change, test, or experiment if the change, test, or experiment would result in more than a minimal increase in the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the final safety analysis report (as updated). Specifically, the licensee implemented a change to Operating Instruction OI-VA-2, Auxiliary Building Ventilation System Normal Operation, 11, Revision 47, after incorrectly concluding that the opening of certain high-energy line break barriers and selected fire barrier doors to allow supplemental cooling of both safety-related switchgear rooms did not increase the likelihood of occurrence of a malfunction of a structure, system, or component important to safety previously evaluated in the final safety analysis report. In response to this issue, the licensee revised entry conditions to Operating Instruction OI-VA-2, Attachment II, to ensure that high energy line break barriers are not impaired prematurely. This finding was entered into the licensees corrective action program as Condition Report CR-2016-06667. Because this violation was entered into the corrective action program to ensure compliance was restored in a reasonable amount of time, and the violation was not repetitive or willful, this Severity Level IV violation is being treated as a non-cited violation (NCV), consistent with Section 2.3.2.a of the Enforcement Policy:

NCV 05000285/2016008-01, Failure to Obtain Prior NRC Approval for a Change When Required.

.2 Permanent Plant Modifications

a. Inspection Scope

The inspectors reviewed 12 permanent plant modifications that had been installed in the plant during the last three years. This review included in-plant walkdowns for portions of the affected systems. The modifications were selected based upon risk significance, safety significance, and complexity. The inspectors reviewed the modifications selected to determine if:

  • the supporting design and licensing basis documentation was updated;
  • the changes were in accordance with the specified design requirements;
  • the procedures and training plans affected by the modification have been adequately updated;
  • the test documentation as required by the applicable test programs has been updated; and
  • post-modification testing adequately verified system operability and/or functionality.

The inspectors also used applicable industry standards to evaluate acceptability of the modifications. The list of modifications and other documents reviewed by the inspectors is included as an Attachment to this report.

This inspection constituted 12 permanent plant modification samples as defined in Inspection Procedure 71111.17-04.

.2.1 Equipment Environmental Qualification Fuse Isolation for HCV-1041A/1042A

The inspectors reviewed Engineering Change 54244, implemented to correct main steam isolation valve component environmental qualification issues. The change installed additional fuses and fuse blocks in the control circuits for valves HCV-1041A and HCV-1042A to provide the necessary isolation between the existing non-environmentally qualified components installed in the harsh environment and the environmentally qualified components that provided required position indication for the main steam isolation valves in the control room. The change also installed an additional indicator light on the main steam isolation valves control switch assembly to indicate the availability of control power to the circuit. The non-environmentally qualified components were associated with the test function and the slow-open function of the isolation valves, neither of which were safety-related functions. The deficiency was identified by the licensee during a review of the plants environmental qualification program. The inspectors did not identify any significant concerns with the engineering change package.

.2.2 Diesel Generator Engine Controls Upgrade

The inspectors reviewed Engineering Change 41956, implemented as a result of an analysis performed by the licensee to identify reasons for repetitive component failures associated with emergency diesel generator system voltage regulator and control circuits and component obsolescence issues. This change was associated with the control circuits only. This change replaced existing problematic electrical relays with relays having higher inductive load break ratings and higher contact ratings, added surge suppression diodes and Zener diodes in parallel with the new relay coils for component protection, installed improved pushbutton switches, replaced existing speed-sensing components with more reliable and efficient solid state devices, and replaced existing power line filters with DC-DC converters. The inspectors did not identify any significant concerns with the engineering change package.

.2.3 Replacement of Conax Electrical Conductor Seal Assembly and Pigtails on Namco Limit

Switches Below the Post Design Basis Accident Submergence Level in Containment The inspectors reviewed Engineering Change 58770, implemented in response to the licensees determination that 10 safety-related valve position limit switches, located inside containment, had Conax electrical conductor seal assemblies with Kapton insulated conductors that did not meet the licensees environmental qualification program requirements for possible submergence below containment flood levels. The limit switches on each valve provided open or closed position indications in the control room and other locations. In response to this condition, the Conax conductor seal assemblies with Kapton insulated pigtails connecting the limit switches to junction boxes, along with the associated flexible conduits, were either relocated or replaced with items that were qualified for the harsh environment and submergence durations defined in plant calculations. The inspectors did not identify any significant concerns with the engineering change package.

.2.4 Component Cooling Water Pump Motor Cable and Conduit Upgrade

The inspectors reviewed Engineering Change 55358, which was implemented after the licensee identified insulation and jacket degradation on power cables for the respective component cooling water pump motors AC-3A-M, AC-3B-M, and AC-3C-M at the motor terminal boxes. The jacketing problems were attributed to an incorrect cable-bending radius during previous installation. The change removed the existing cabling from the motor connection terminal boxes out to the cable trays, installed new cabling having a slightly smaller cross-sectional area into conduit to facilitate better in-line connection geometry, installed new junction boxes to house the replacement cable connections, and improved the motor terminal connections. After required derating factors were applied, the new cable assemblies had a higher ampacity rating, resulting in improved margin. The inspectors did not identify any significant concerns with the engineering change package.

.2.5 TR-408 Spent Fuel Pool Temperature Recorder

The inspectors reviewed Facility Change 38103, in part, to establish a comparison between different plant change processes and methods of implementation. Specifically, this facility change was implemented to integrate spent fuel pool temperature monitoring into the plant distributed control system and the emergency response facility computer system following the failure of the original TR-408 recorder. The licensee temporarily replaced the failed recorder with a digital recorder and subsequently performed this change to connect the spent fuel temperature detector assemblies to a data acquisition system, which provided inputs to the distributed control system and emergency response facility computer system. The new system also provides input to the plant data historian system and additional user-defined setpoints that were configured to provide additional temperature data to the control room operators. The inspectors did not identify any significant concerns with the facility change package.

.2.6 Raw Water Strainer Upgrade

The inspectors reviewed Engineering Change 41587, implemented to address the safety-related classification of the raw water pump discharge strainer internals. As originally designed, the strainer casings were the only safety-related components based on the pressure boundary function associated with passing sufficient flow to meet design basis cooling requirements. The internal, rotating basket, associated drive mechanism, and backwash function were not classified as safety-related. However, as subsequently determined by the licensee, a loss of function of the strainer internals could have compromised the credited raw water flow rate under accident conditions or compromised safety-related components downstream due to debris in the system from a failure of the strainer internals. In response to this condition, this engineering change was developed to address the concerns regarding the current nonsafety classification of the strainer internals. Specifically, the inspectors reviewed the engineering change package, vendor manuals, system drawings, alarm response procedures, surveillance tests, preventive maintenance tasks, work orders, corrective action documents, and performed a system walkdown. The inspectors did not identify any significant concerns with the engineering change package.

.2.7 Modify Piping and Supports for FW-10 Main Steam Supply in Response to High-Energy

Line Break Concerns The inspectors reviewed Engineering Change 53202, implemented to address a non-conforming condition associated with overstressed steam supply piping to the turbine-driven auxiliary feedwater pump FW-10. The licensees high-energy line break analysis reconstitution project identified that portions of the steam supply piping to pump FW-10 were overstressed when the main steam system was aligned to the pump. The purpose of this engineering change was to implement the required modifications to the piping and piping supports identified in the analysis to eliminate code check overstresses and high-energy line breaks and cracks. Specifically, the inspectors reviewed the engineering change package, system drawings, stress analyses, post-modification tests, field design change requests, work orders, FW-10 trend data, corrective action documents, and performed a system walkdown. The inspectors did not identify any significant concerns with the engineering change package.

.2.8 Equipment Environmental Qualification Requirements for Feedwater Regulating Bypass

Valves HCV-1105 and HCV-1106 The inspectors reviewed Engineering Change 54173, implemented to provide environmentally qualified equipment to control feedwater regulating bypass valves HCV-1105 and HCV-1106. The purpose of the engineering change was to maintain the capability to control steam generator level during accident conditions during a high-energy line break in room 81. This capability is a nonsafety-related function of the valves; however, the valves must be qualified to operate in an adverse environment.

Specifically, the valves are opened to provide an alternate path for auxiliary feedwater flow to the steam generators and must also function to close to avoid overfilling the steam generators. The inspectors reviewed the engineering change package, system drawings, post-modification tests, system operating procedures, master list for equipment qualification, field design change requests, work orders, preventive maintenance tasks, and corrective action documents. The inspectors did not identify any significant concerns with the engineering change package.

.2.9 Upgrade for High-Energy Line Break Volumetric Inspection

The inspectors reviewed Engineering Change 61599, implemented to replace existing two inch and larger socket welded joints with butt welds in selected portions of the chemical volume and control system and steam generator blowdown piping in room 13.

Specifically, this modification ensured that the welded joints, between the affected systems containment penetration and the outboard isolation valves were accessible for volumetric inspection. The inspectors reviewed the engineering change package, system drawings, stress analyses, post-modification tests, field design change requests, work orders, and corrective action documents. The inspectors did not identify any significant concerns with the engineering change package.

.2.10 Pressurizer Heater Weld Configuration Change

The inspectors reviewed Engineering Change 54959, implemented to replace pressurizer heater number 26, with a revised weld design. Specifically, this modification incorporated an evaluation of the critical characteristics for an alternate replacement weld design consistent with Calculation FC 08074, Pressurizer Heater Number 26, Weld Configuration, American Society of Mechanical Engineering,Section III, Design Report. The conclusion of the calculation established that the pressurizer heater replacement weld satisfied the requirements of ASME Code,Section III, and that the weld was qualified for the specified number of cycles defined in the Fort Calhoun pressurizer specification. The inspectors reviewed the design report, engineering change package, and the stress analysis. The inspectors did not identify any significant concerns with the engineering change package.

.2.11 Pipe Supports for Component Cooling Water Piping in Containment

The inspectors reviewed Engineering Change 54436, implemented to remove, upgrade, and install piping supports in the component cooling water system. The inspectors also reviewed Condition Report CR-2011-7938, which documented that the analysis of record, for the component cooling water piping to the containment coolers, did not adequately consider the additional heating and thermal stresses associated with a design basis accident. Accordingly, this design change was implemented to restore the affected pipe supports to the current design basis condition including extended power uprate conditions. The inspectors reviewed the design change documentation, including selected stress analysis calculations and conducted interviews with the cognizant design engineering personnel. The inspectors did not identify any significant concerns with the engineering change package.

.2.12 Replacement of Main Feedwater Check Valves FW-161 and FW-162

The inspectors reviewed Engineering Change 26174, implemented to replace the main feedwater check valves FW-161 and FW-162 and the associated restraints. Specifically, this modification replaced the existing check valves with an improved design which allowed inservice testing for closure stroking without having to remove the valves from their installed position. This modification was installed in conjunction with substitute replacement Engineering Change 29682, which replaced the main feedwater piping downstream of FW-161 and FW-162, up to the steam generators. This modification was implemented because the replacement check valves were physically longer than the existing components. The inspectors reviewed the engineering change package, system drawings, post-modification tests, field design change requests, work orders, and corrective action documents. The inspectors did not identify any significant concerns with the engineering change package.
