Pilgrim Nuclear Power Station was performing planned testing on the Reactor Core Isolation Cooling (RCIC) when the HPCI System isolated.
Accordingly, the HPCI System was declared inoperable.
IThe Technical Specifications Limiting Conditi9n for Statement 3.5.C.2 was entered and planned troubleshooting into the cause of the HPCI isolation was started. This event is reportable under 10 CFR 50. 73(a)(2)(v)(D), any event or condi.tion that could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
There was no impact to public health and safety from this condition.

- 1. FACILITY NAME 2. DOCKET NUMBER 3. LERNUMBER Pilgrim Nuclear Power Station 05000-293 YEAR 2017 NARRATIVE BACKGROUND SEQUENTIAL NUMBER -002 REV NO. -00 The High Pressure Coolant Injection (HPCI) System is provided to ensure that the reactor core is adequately cooled to limit fuel clad temperature in the event of a small break in the nuclear system and loss of coolant which does not result in rapid depressurization of the reactor vessel. The HPCI System permits the reactor to be shut down while maintaining sufficient reactor vessel water inventory until the reactor vessel is depressurized.
HPCI continues to operate until reactor vessel pressure is below the pressure at which Low Pressure Coolant Injection or Core Spray systems would maintain core cooling. EVENT DESCRIPTION On March 27, 2017, at 1825 [EDT], with the reactor at 100 percent core thermal power and steady state conditions, the HPCI System was declared inoperable and Technical Specifications (TS) Limiting Condition for Operation (LCO) Action Statement (AS) 3.5.C.2 was entered. Pilgrim Nuclear Power Station (PNPS) personnel were performing planned testing of the Reactor Core Isolation Cooling (RCIC) System per TS Table 4.2.B. During the test, it has been determined that plant personnel heated the wrong temperature switch causing the HPCI system to isolate. CAUSE OF THE EVENT The Direct Cause of the event was the application of heat to a HPCI temperature switch. The system responded as designed and the HPCI primary containment isolation valves closed making HPCI unavailable.
The Root Cause of this event is two Nuclear Controls Technicians decided to deviate from procedure requirements while procedure 8.M.2-2.6.3 Attachment 1, RCIC Steam Line High Temperature Instrument Functional Test. CORRECTIVE ACTIONS The corrective action to preclude repetition documents that both individuals' qualifications have been removed and their site access restricted.
Specific disciplinary actions have been taken with the individuals involved pursuant to the requirements of 10 CFR 73.56(c). . NRG FORM 366A (04-2017)

- 1. FACILITY NAME 2. DOCKET NUMBER 3. LERNUMBER YEAR Pilgrim Nuclear Power Station 05000-293 2017 SAFETY CONSEQUENCES SEQUENTIAL NUMBER -002 REV NO. -00 IThere are no consequences to the general safety of the public, nuclear safety, industrial safety and radiological safety from this event. The isolation of HPCI has been evaluated and it has been determined that the individuals involved were not following procedure requirements for performing testing. The loss of safety created by isolating the HPCI System lasted for only thirty three minutes during this evolution.
No additional actions to reduce the consequence are necessary.
REPORT ABILITY IThis report is submitted in accordance with 10 CFR 50.73(a)(2)(v)(D), any event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.
PREVIOUS EVENTS A review of Pilgrim Station License Event Reports (LE Rs) for the past 10 years was performed.
The focus of review was LERs that involved loss of HPCI system function.
The following LERs were reviewed:
LER 2008-004 -HPCI System Inoperable Due to Undervoltage Relay Failure in Power Supply Circuit LER 2011-006 -HPCI System Inoperable Due to Governor Control Valve Mechanical Binding LER 2013-006 -HPCI Flow Controller Failure to Achieve Rated Flow while in Auto Mode LER 2016-009 -HPCI Declared Inoperable Due to Failed lnservice Testing IThese LER events do not identify any similar failure mechanisms to that described in this LER.
