Event Notification Report for July 28, 2016

SOURCE RANGE INSTRUMENTS READING IMPROPERLY DURING A REACTOR STARTUP

"This four and eight hour notification is being made to report that at 0541 [EDT] on 7/28/16, Salem Unit 1 initiated a shutdown to comply with Technical Specifications due to the inoperability of both source range nuclear instruments. During a reactor startup, with Unit 1 in Mode 2, both source range instruments were reading approximately one decade lower than expected compared to intermediate range and Gamma-Metric instruments and due to the proximity to the estimated critical condition. The condition could also have prevented the fulfilment of the source range instruments safety function to trip the reactor when required.

"Salem Unit 1 is currently stable in Mode 3. Reactor Coolant system pressure is 2235 psig and reactor coolant system temperature is 547 F with decay heat removal via the main steam dump and auxiliary feedwater systems. Unit 1 has one active shutdown tech spec action statement in effect due to the inoperability of the containment radiation monitor 1R11A. The inoperability of this radiation monitor had no effect on the event. All control rods were manually inserted to place Unit 1 in Hot Standby (Mode 3). No ECCS [emergency core cooling system] or ESF [emergency safety features] systems were required to function during this event.

"No major secondary equipment was tagged for maintenance prior to this event. No personnel were injured during this event."

The reactor was manually shut down and a shutdown margin calculation verified sufficient margin.

The licensee notified the NRC Resident Inspector and the local township.

* * * RETRACTION FROM MATT MOG TO VINCE KLCO ON 9/26/16 AT 1519 EDT * * *

"The purpose of this notification is to retract event report number 52129 made on 7/28/2016 at 0925 (EDT). Previously PSEG reported that Salem Unit 1 initiated a shutdown to comply with Technical Specifications (TS) due to the inoperability of both source range nuclear instruments. Additionally PSEG reported that the condition could have prevented the fulfillment of the safety function needed to, 'Shut down the reactor and maintain it in a safe shutdown condition.'

"Subsequent review identified that the condition did not meet either reporting criteria. Maintenance and Engineering evaluation of the source range nuclear instruments determined that the instruments were fully operable at the time of the event. TS 3.3.1.1, Reactor Trip Instrumentation remained met, no TS shutdown was required and the instruments were capable of performing their required function.

"Therefore PSEG is retracting the notifications made under 10 CFR 50.72(b)(2)(i) and 10 CFR 50.72(b)(3)(v)(A).

"The NRC Resident Inspector was notified of this retraction by the licensee."

POSTULATED FIRE EVENT THAT COULD ADVERSELY IMPACT SAFE SHUTDOWN EQUIPMENT

"A review of the Beaver Valley Unit 2 Fire Protection Safe Shutdown Report (FPSSR) found that a postulated fire had the potential to spuriously open all three individual steam generator atmospheric dump valves in addition to a common residual heat release valve. Previous analysis did not consider all of the valves spuriously opening from a fire. The potential impact of these valves spuriously opening is a cooldown that could adversely affect shutdown margin.

"Hourly fire tours have been put in place for those fire areas that have the potential to initiate this condition.

"This condition is reportable as an 8 hour report in accordance with 10 CFR 50.72(b)(3)(ii)(B).

"The NRC Resident Inspector was notified."

This condition is not applicable to Unit 1.

* * * RETRACTION FROM DAN SCHWER TO VINCE KLCO ON 9/26/16 AT 1428 EDT * * *

"Retraction of EN 52132 'Postulated Fire Event That Could Adversely Impact Safe Shutdown Equipment'.

"On 07/29/2016, an 8-hour notification (EN 52132) was made describing the discovery of a postulated fire event that could adversely impact safe shutdown equipment, specifically the spurious opening of the three Atmospheric Steam Dump Valves (ASDVs) and the Residual Heat Release (RHR) Valve, simultaneously. This notification was made pursuant to 10 CFR 50.72(b)(3)(ii)(B) as an unanalyzed condition because of the potential effect on shutdown margin. Further engineering evaluation has determined that the required shutdown margin is not challenged by the event, as bounded by previous analysis of a similar scenario as well as validated operator actions. Therefore, this does not result in a reportable condition.

"The Resident NRC Inspector has been notified."

Notified the R1DO (Cook).

TEMPORARY LOSS OF POWER TO THE EMERGENCY CONDENSER

"On 7/28/2016 at 2357 EDT, Nine Mile Point Nuclear Station Unit 1 experienced a fault in the in-service 11 RPS UPS [Reactor Protective System Ultimate Power Supply], resulting in an isolation of both emergency condensers. Emergency condenser 12 was returned to standby on 7/29/2016 at 0041 EDT and emergency condenser 11 was returned to standby on 7/29/2016 at 0045 EDT.

"This 8-hour non-emergency report is being made based upon requirements of 10CFR50.72(b)(3)(v)(B) which states, 'Licensee shall notify the NRC of any event or condition that at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to: (B) Remove residual heat.'

"The state of New York and the NRC Senior Resident Inspector were informed."

MEDICAL EVENT - WRONG RADIOPHARMACEUTICAL FORMULATION ADMINISTERED TO PATIENT

A nuclear technologist ordered and administered 25 mCi of Technetium 99m-methyl diphosphonate (99mTc MDP) to a patient undergoing a gastric emptying scan. 99mTc MDP is a radioisotope used especially for bone scans. The formulation that should have been ordered and administered is 500 microCuries of Tc 99m Sulfur colloid, which is generally used for the gastric study.

Both the patient and prescribing physician have been notified. The dose received by the patient is under evaluation at this time. No harmful effects to the patient are expected.

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

* * * RETRACTION FROM DAVID WISHKO TO DANIEL MILLS AT 1323 EDT ON 08/02/2016 * * *

Upon further analysis, the dose administered to the patient did not exceed the limits listed in 10 CFR 35.3045, and therefore this event is not reportable.
