PLANT STATUS
Unit 1 began the inspection period at or near rated thermal power. On March 17, 2018, operators reduced reactor power to 12 percent and inserted a planned manual reactor scram for a planned maintenance outage. On March 19, 2018, operators commenced a reactor startup and raised Unit 1 to rated thermal power. On March 20, 2018, operators reduced reactor power to 70 percent to perform a control rod pattern adjustment. Unit 1 was restored to rated thermal power on March 21, 2018. On March 24, 2018, operators reduced power to 70 percent to perform a rod pattern adjustment. On March 25, 2018, operators restored reactor power to rated thermal power. Unit 1 remained at or near rated thermal for the remainder of the inspection period.
Unit 2 began the inspection period at or near rated thermal power. On February 2, 2018, operators reduced reactor power to 75 percent to perform a rod pattern adjustment. Operators restored power to rated thermal power on February 3, 2018. On February 24, 2018, operators reduced reactor power to 75 percent to perform turbine valve testing and a control rod pattern adjustment. On February 25, 2018, operators restored reactor power to rated thermal power.
On March 22, 2018, Unit 2 began coastdown, after reaching the maximum power achievable due to fuel depletion as Unit 2 was at the end of this operating cycle. At the end of the inspection period Unit 2 was at 98 percent power. The maximum power will continue to decrease (coastdown) until the refueling outage, which is planned for the second quarter of
INSPECTION SCOPES
Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase.

INSPECTION RESULTS
Unresolved Item Potential Failure to Submit an 8-Hour Event 71111.20 (URI) Notification for a Valid Actuation of HPCI Refueling and 05000220/ Other Outage 2018001-01 Activities (Open)
Description:
On March 18, 2018, at 1:18 a.m., during the Unit 1 maintenance outage while the unit was in cold shutdown, operators received multiple low level alarms on the GEMAC 11 and 12 level indications. Operators responded by adjusting reactor water cleanup reject flow and the feedwater minimum flow control valve to raise reactor water level. Upon the operators making the adjustment to reactor water level, the feedwater low flow control valve was slow to respond, but eventually opened more rapidly, and the increased flow from feedwater resulted in a rapid rise in reactor water level. At 1:28 a.m., indicated reactor water level rose to the 95-inch trip setpoint for the 11 and 12 Yarway level indication instruments, resulting in a turbine trip and HPCI initiation signal. The HPCI pumps were tagged out and thus did not inject, and the turbine was offline for the shutdown.
The 11 and 12 Yarway level indication instruments provide reactor protection system logic inputs for reactor vessel water level; however, the Yarway level indication instruments are not density compensated. Therefore, under cold shutdown conditions, actual reactor vessel water level was lower than indicated water level on the 11 and 12 Yarways. During cold shutdown conditions, the GEMAC level instruments, which are calibrated to cold shutdown conditions, provide an accurate indication of actual reactor vessel water level. The GEMAC instruments both indicated well below the trip setpoint of 95 inches (indicated ~72 inches) when the turbine trip and HPCI initiation signal were received. Exelon determined that this event was not reportable under 10 CFR 50.72.
Title 10 CFR 50.72(b)(3)(iv)(A) states, Any event or condition that results in valid actuation of any of the systems listed in paragraph (b)(3)(iv)(B) of this section, except when the actuation results from and is part of a pre-planned sequence during testing or reactor operation.
(B) The systems to which the requirements of paragraph (b)(3)(iv)(A) of this section apply are:
- (5) BWR reactor core isolation cooling system; isolation condenser system; and feedwater coolant injection system.
Planned Closure Action(s): The inspectors requested the 10 CFR 50.72 subject matter experts at the Office of Nuclear Reactor Regulation (NRR) and Office of General Council (OGC) to review whether this was a valid actuation and thus reportable. The inspectors are opening an unresolved item (URI) to determine if a performance deficiency exists.
Licensee Action(s): Licensee entered the concern into their corrective action program, and communicated with NRC Region I and NRR Staff. Exelons position is that the event was not reportable.
Corrective Action Reference: IR 04116336 NRC Tracking Number: 05000220/2018001-01 URI Potential Inadequate 50.59 Evaluation for TS 3.3.1.1 71111.18 05000410/ Bases Change Plant 2018001-02 Modifications (Open)
Description:
On February 23, 2018, Exelon personnel performed a 50.59 Screening for a change to Unit 2 TS Bases 3.3.1.1, Reactor Protection System (RPS) Instrumentation, for MSIV and TSV surveillance testing. Exelon personnel performed this activity to address operating experience associated with the use of a test box that prevents a scram signal during RPS surveillance testing for TS 3.3.1.1 Function 5 MSIV - Closure and Function 8 TSV -
Closure.
TS Bases B 3.3.1.1, C.1, Revision 1 was revised to state, in part, For Function 5 (MSIV -
Closure), this would require both trip systems to have at least one channel associated with the MSIVs for each main steam line in one Trip Logic Channel (not necessarily the same main steam lines for both trip systems), Operable or in trip (or the associated trip system in trip).
For Function 8 (Turbine Stop Valve - Closure), this would require both trip systems to have the channels for one Trip Logic Channel, Operable or in trip (or the associated trip system in trip).
The inspectors questioned whether the change to TS Bases B 3.3.1.1 resulted in a change to the implementation of TS 3.3.1.1. A licensee is permitted to make changes to their Technical Specification Bases documents without NRC review and approval. However, in certain cases, such as a change to the Technical Specification Bases that would change how the associated Technical Specification is applied, NRC review and approval would be required.
Planned Closure Action(s): The inspectors sent written questions to request assistance from NRR to determine whether this change to the TS Bases reasonably would have required NRC review and approval. The inspectors are opening a URI to determine if this is violation of 10 CFR 50.59 and if it is more than minor.
Licensee Action: Documented NRCs concern as AR 04055602. Exelons position is the change would not affect how TS 3.3.1.1, or its note, is applied and therefore NRC review was not required.
Corrective Action Reference: AR 04055602 NRC Tracking Number: 05000410/2018001-02 Observations and Minor Violations 71152 A Problem Identification and Resolution The inspectors performed a review of IR 04049445 to review Exelons cause evaluation associated with a Unit 1 reactor scram on low reactor water level on September 6, 2017. The inspectors also reviewed Exelons Post Transient Review, operating procedures, drawings, Control Room Logs, sequence of events recorder data, plant computer data, and conducted interviews with Exelon staff.
The inspectors identified two performance deficiencies that were determined to be minor in accordance with IMC 0612, Appendix B, Issue Screening, associated with Exelons Post Transient Review. The purpose of a Post Transient Review is to make a prompt determination if plant equipment responded as designed and that plant operators responded appropriately to the transient or event and any potential non-conforming conditions identified.
- (1) OP-AA-108-114, Post Transient Review, Revision 13, Section E Safety Assessment, Criteria 10 states High level isolation(s) with a check box for either Yes or No. During the inspectors review, it was identified through review of plant computer data and drawings that Nine Mile Point Unit 1 received an expected signal for a feedwater pump trip on high reactor water level at 95 inches. The inspectors found that operators performing the Post Transient Review in accordance with OP-AA-108-114 made a determination that the feedwater pump trip on high reactor water level was not considered an isolation. The inspectors determined that the procedure lacked clarity in providing operators a means to determine if the plant responded in accordance with its design basis. The inspectors determined that although operators did not accurately check the box Yes that the feedwater pump high reactor water level trip occurred, it did not result in any consequence to the plants operation following the Post Transient Review; and it was determined that the trip did function as expected, therefore this performance deficiency for an inadequate procedure is minor.
- (2) The inspectors also reviewed IR 04050697, which documented a question from the inspectors following the reactor scram on September 6, 2017, concerning feedwater computer points becoming erratic just prior to the Unit 1 reactor scram. Exelon subsequently performed additional evaluation, and was able to show that the failure of the computer points were unrelated to the cause of the scram, which was the failure of the feedwater flow/steam flow mismatch card. Exelon determined the computer point failures to be related to maintenance being performed on a power supply that failed in the turbine performance calculation cabinet under work order C93638038. The inspectors agreed with this conclusion.
The inspectors determined that Exelon failed to establish documentation to support or refute a potential cause in accordance with Procedure MA-AA-716-004, Conduct of Troubleshooting, Revision 15, as part of Section 4.5 for Simple Troubleshooting. The result was a failure to provide the cause evaluation team enough information to assess the issue for a potential cause. Specifically, Procedure PI-AA-125-1003, Corrective Action Program Evaluation Manual Section 4.3.5 states that investigators should gather information and data relating to the event. The inspectors found that this potential failure was not explored under the Simple Troubleshooting process for establishing a failure mode/cause table, and subsequently resulted in the inspectors questioning if this should have been evaluated by the cause evaluation team. This showed that the depth of investigation was inadequate to ensure all potential causes associated with a potential scram were explored. The inspectors determined the performance deficiency for failure to follow Procedures MA-AA-716-004 and PI-AA-125-1003 is minor because following the inspectors questions, Exelon was able to provide additional information to refute relationship to the cause of the scram.
Observations and LER Closure 71153 Follow-up of Events and Notices of Enforcement Discretion LER 05000220/2017-003, Automatic Reactor Scram due to Reactor Vessel Low Water Level, on September 6, 2017. Exelon determined the root cause of the Unit 1 event was an equipment failure associated with a power supply within the proportional amplifier PAM-ID23E, which is part of the three element feedwater control system. This failure was not within Exelons ability to foresee and prevent; therefore, there was no performance deficiency associated with the instrument failure. The inspectors did not identify any findings associated with this event. This LER is closed.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On April 25, 2018, the inspectors presented the quarterly resident inspection results to Mr. Peter Orphanos, Site Vice President, and other members of the Exelon staff.
