SU.1.4 System Operational Readiness Assessment Inspection (Inspection Procedure 93806)
a. Inspection Scope
Inspection Activities: The inspectors reviewed the system turnover processes associated with the completion of construction activities and turnover of Unit 2 systems to operations to ensure the licensee was following the requirements of procedures 0-TI-37, "Systems Turnover to Operations," Rev. 0, 0-TI-435, "Engineering Programs and Components Turnover", Rev. 3, and 0-TI-441, "Operational Readiness Process for Unit 2 Systems," Rev. 6. The inspectors reviewed system 74, residual heat removal, and system 62, chemical and volume and control. As part of the review, the inspectors verified that equipment turnover deferral items were adequately justified and equipment punch-list items were appropriately dispositioned. The inspectors reviewed selected WOs, design changes, and program and component evaluation reports to verify that overall system condition and capability suppor ted system turnover. The inspectors interviewed selected control room operators and work management control operators to ensure they were knowledgeable of the procedures governing the system turnover process and changes in plant status configuration controls. The inspectors reviewed a sample of outstanding WOs for each system to verify that there were no significant open WOs that could impact the current mode of operation. The inspectors verified that a sample of design changes had been translated to system operating procedures.
Additionally, the inspectors performed partial system walkdowns of each system in accordance with IP 71111.04, "Equipment Alignment."
17 The inspectors performed an independent review of completed 0-TI-37 and 0-TI-441 packages for to determine whether the activities were accomplished in accordance with NRC requirements and licensee procedures.
During the review of the 0-TI-37 packages the inspectors performed the following:
- The inspectors reviewed Attachment 2, "Functional Support Requirements Completion Checklist and Required Drawings," to verify that Controlled Critical drawings were transferred to the main control room and the online Business Support Library (BSL). The inspectors verified two material equipment list items switched to "operating" control.
- The inspectors reviewed Attachment 3, "Startup Testing Complete Form," to verify that deferrals were assessed for impact on operability and qualification.
- The inspectors reviewed Attachment 4, "Turnover Boundary Walkdown Form," to verify that any incomplete deficiencies were assessed for impact on operability or qualification.
- The inspectors reviewed Attachment 5, "Design Engineering Complete Form," and sampled two design documents to verify they were completed.
- The inspectors reviewed Attachment 6, "Functional System Turnover Agreement Form."
- The inspectors reviewed Attachment 7, "Supporting Documentation," to verify that a list of deferrals or special operating conditions, if any, had been assessed for impact on operability or qualification.
- The inspectors reviewed Attachment 11, "Turnover Open Issue Summary Form," to verify all issues identified on the preceding attachments were captured on this summary form.
- The inspectors reviewed Appendix A, "Turnover Action Deferral Form," to verify that a list of deferrals or special operating conditions, if any, had been assessed for impact on operability or qualification. The inspectors verified that any deferrals were dispositioned appropriately in the associated 0-TI-441 review for the system.
- The inspectors reviewed Appendix B, "Special Operating Conditions Form," to verify that the licensee had listed and assessed special operating conditions that could impact operability or qualification and that they were resolved in the associated 0-TI-441 package.
During the review of the 0-TI-441 packages the inspectors performed the following:
- The inspectors reviewed Appendix A, "Boundary Health Indicator Worksheet," to verify all non-Green system attributes do not adversely impact operability requirements for the system.
- The inspectors reviewed Appendix C, "Rescission Process Form,"to note any system or components returned by Operations to Nuclear Construction and verify that deficiencies were resolved and the system or component was returned to
Operations.
- The inspectors reviewed Attachment 1, "Functional Support Requirements," and sampled to verify that system operating instructions and alarm response instrctions were complete, auxiliary unit operator rounds reflected ownership of the system, and any outstanding clearances did not affect operability of the system.
- The inspectors reviewed Attachment 2, "Operational Alignment Form," to verify that all applicable attributes of the system (Appendix R, etc.) in 0-TI-435, 18 "Engineering Programs and Components Turnover, "support system operability. The inspectors verified that all open design changes were complete or had been
evaluated not to adversely impact system operability. The inspectors verified by sample that surveillance, maintenance, chemistry, radiological, and engineering procedures for the system were available in document control (BSL). The inspectors verified that outstanding items potentially affecting operability from the 0-TI-37 process were reflected in the limiting condition for operation tracking system.
- The inspectors reviewed Attachment 3, "Licensing Actions Complete," to verify that no outstanding licensing actions remained for the system.
- The inspectors verified that Attachment 4, "Declaration of System Boundary Ready to Operate," was complete.
The inspectors evaluated the licensee corrective actions on problems identified and entered into the corrective action program. The inspectors reviewed the following CRs to verify that equipment alignment discrepancies had been appropriately characterized and corrected:
- CR 1044257, "0-TI-441 Process for Dual Unit System Descriptions."
- CR 1129514, "2-FCV-63-130 failed to operate, 2-THV-63-130 found closed."
- CR 1129486,"Solid State Protection System troubleshooting with jumpers installed, revised without using appropriate work order revision."
- CR 1125217, "2-ISV-67-557B and 2-ISV-67-523B containment ERCW valves closed, valves required to be locked open."
b. Observations and Findings
No findings were identified. The inspector's review of all outstanding WOs indicated that there were no safety significant issues related to their functionality for Mode 4 operation. The inspectors observed that the system turnover procedures (0-TI-37 and 0-TI-441) did not require a formal system component alignment to ensure that the systems could meet all of their functional requirements. As noted above, CRs were initiated to address examples of incorrect equipment alignment that were revealed during routine plant
operations.
c. Conclusions
The licensee met the procedural requirements of 0-TI-37, 0-TI-435, and 0-TI-441 for system 62 and system 74. Additional systems will be inspected to evaluate system turnover to operations.

OA.1.2 (Closed) Three Mile Island Action Item II.D.1, Relief and Safety Valve Test Requirements (Inspection Procedures 50073 and 50075)
a. Inspection Scope
Background: Following the 1979 event at Three Mile Island (TMI) Unit 2, the NRC formed a Lessons Learned Task Force to provide recommendations from the accident, which were released in NUREG-0578 (ADAMS Accession No. ML090060030). TMI Action Items were developed as a result of those recommendations and published in NUREG-0660 Volumes 1 and 2 (ADAMS Accession Nos. ML072470526 and ML0727470524). Specifically, TMI Action Item II.D.1 established the requirements for licensees and applicants to conduct testing in order to qualify reactor coolant system (RCS) relief and safety valves under expected operating conditions for design basis transients and accidents, including under Anticipated Transient without SCRAM (ATWS) conditions. NUREG-0737 (ADAMS Acce ssion No. ML051400209) clarified this statement, adding the qualification of pressurized water reactor (PWR) block valves as a
new requirement.
To complete TMI Action Item II.D.1, Sections A.2, A.3, B, and C, respectively, the inspectors previously concluded that:
- The licensee completed analyses to demonstrate the functionality of the as-installed primary relief and safety valves, including the effect of as-built discharge piping on valve operability;
- The licensee's criteria for success and failure of valves tested was adequate;
- The licensee completed tests to demonstrate the block valves between the pressurizer and each PORV could be operated, closed, and opened for all fluid conditions expected under operating and accident conditions; and
- The relief and safety valves are not required during an ATWS condition.
These inspection activities were documented in the following inspection reports:
- 05000391/2015610, Section OA.1.2, (ADAMS Accession No. ML16041A520)
- 05000391/2015609, Section OA.1.4, (ADAMS Accession No. ML15287A199)
- 05000391/2014604, Section OA.1.7, (ADAMS Accession No. ML14177A214)
Also documented in those inspection reports, for TMI Action Item II.D.1, Section A.1, the inspectors previously concluded that the licensee completed tests to demonstrate that the pressurizer code safety valves operated successfully and were set to the pressure required by the Watts Bar Unit 2 FSAR and ASME Boiler and Pressure Vessel Code (BPVC)Section III. The inspectors also concluded that the licensee demonstrated that the PORVs could open and reclose under the expected flow conditions through pressurizer and pressurizer relief tank data gathered during hot functional testing. However, at the time, the licensee was unable to verify functionality of the valve reed 22 switches and corresponding light indications in the control room to verify the PORVs stroked within the required two second interval.
Inspection Activities: The inspectors reviewed licensee actions to satisfy the requirements of TMI Action Item II.D.1, Section A.1. Specifically, during Mode 5, with a steam bubble in the pressurizer, the inspectors witnessed the licensee's performance of surveillance instructions 2-SI-68-904-A, "Reactor Coolant System Valve Position Indication Verifications (Train A)," and 2-SI-68-904-B, "Reactor Coolant System Valve
Position Indication Verifications (Train B)," for PORVs 2-PCV-68-340A and 2-PCV-68-334 respectively, to verify:
- The PORVs fully opened and closed within the required stroke time of two seconds;
- The reed switches on the valves and corresponding light indications in the control room functioned properly; and
- The temperature element downstream of the PORVs identified the increase in temperature when the PORVs stroked open and alarmed the associated annunciator in the control room.
Documents reviewed are listed in the Attachment.
b. Observations and Findings
No findings were identified.
c. Conclusion The inspectors concluded that the work performed by the licensee was adequate to complete TMI Action Item II.D.1, Section A.1, and as a result, that section is now considered closed. The inspectors previously considered TMI Action Item II.D.1, Sections A.2, A.3, B, and C closed in the inspection reports listed above. Therefore, in its entirety, Three Mile Island Action Item II.D.1, Relief and Safety Valve Test Requirements is considered closed.
OA.1.3 (Closed) Temporary Instruction 2500/19, Inspection of Licensee's Actions Taken to Implement Unresolved Safety Issue A-26: Reactor Vessel Pressure Transient Protection for Pressurized Water Reactors (PWRs)
a. Inspection Scope
Background: TI 2500/19 was previously inspected and discussed in IIR 05000391/2013607, Section OA.1.4 (ADAMS Accession No. ML13273A512), and IIR 05000391/2015605 (ADAMS Accession No. ML15226A345). Background details are discussed in those inspection reports.
Inspection Activities: Sections 05.01 (Design) and 05.02 (Administrative Controls and Procedures) of TI 2500/19 were inspected and documented in IIR 05000391/2013607. Sections 05.03 (Training and Equipment Modifications) and 05.04 (Surveillance) of TI 2500/19 were inspected and documented in IIR 05000391/2015605. The remaining portion of Section 05.04 was the review of pressurizer PORV testing.
23 During this inspection, the inspectors observed the most recent measurement of PORV stroke times and compared it with the value in the design basis. As noted in section OA.1.2 of this inspection report, the inspectors witnessed the licensee's performance of surveillance instructions 2-SI-68-904-A, "Reactor Coolant System Valve Position Indication Verifications (Train A)," and 2-SI-68-904-B, "Reactor Coolant System Valve
Position Indication Verifications (Train B)," for PORVs 2-PCV-68-340A and 2-PCV-68-334 respectively. The inspectors performed a cursory review of the test data results to verify that the PORVs fully opened and closed within the required stroke time of two seconds. The acceptance criteria values were compared with the system description and test scoping document to verify that the acceptance criteria met the value in the design basis.
Documents reviewed are listed in the Attachment.
b. Observations and Findings
No findings were identified.
c. Conclusions
Based on the results of this inspection and previous inspections, the inspectors' review concluded that the licensee has implemented an effective mitigation system for low-temperature overpressure transient conditions at WBN Unit 2. No further inspection is required for TI 2500/19. TI 2500/19 is closed.
