"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."

"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 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."

The following information was received by the Commonwealth of Massachusetts:
"The licensee called the Agency [Massachusetts Radiation Control Program] to report a fixed fill level gauge stuck in the open position. The gauge is a Berthold LB7400 Series gauge, Model LB7440, and contains a 150 mCi Cs-137 source [S/N:1476].
"The gauge is mounted to a liquid holding tank which was emptied and was scheduled for routine cleaning. Before cleaning of the tank could begin, the gauge shutter was attempted to be put into the closed position. When attempting to close the shutter, the handle broke off and left the gauge stuck in the open position. Cleaning was not able to be performed and no one was able to enter the tank. The gauge remains in the installed position and is in an inaccessible area with safety controls in place to prevent access. The manufacturer was contacted and will be servicing the gauge 09/27/16 thru 09/28/16 by either repairing or replacing the shielding as necessary.
"The Agency continues to investigate and considers this event to be open.
"Manufacturer of gauge notified and will respond to assess the device; repair or replacement as necessary." |

| Event Text AGREEMENT STATE REPORT - FIXED GAUGE SHUTTER FAILURE
The following information was received from the State of Illinois by email:
"The licensee's radiation safety officer contacted the Agency [Illinois Emergency Management Agency] on September 16, 2016 to advise that while a licensed contractor was conducting calibration of sensors, the shutter failed on an older KayRay fixed gauge. The gauge is mounted on a process line in a remote location that is normally not accessible. Workers were putting the gauge back into service when it appeared that a shear pin broke on the lever that controls the shutter position. The area was cleared of workers and radiation measurements performed. Those measurements showed the shutter was not completely closed. No exposures to workers were noted. Arrangements are being made with a specifically licensed contractor to make repairs to the gauge as soon as can be managed."
Fixed gauge is manufactured by KayRay/Sensall; Model 7063P; Serial Number S98L2001; Sealed Source Gauge (.331 Ci of Cs-137).

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - RADIOACTIVE SEED PACKAGE FAILED TO REACH FINAL DESTINATION
The following information was received from the State of Illinois by email:
"The radiation safety officer, (RSO) at GE Healthcare, called to advise that a package of I-125 seeds which had been given to [a common carrier] to deliver to Sydney, Australia had not reached their destination by the desired date. The package is 6x6x6 inches box of 'excepted package - limited quantity' which contains 10 sealed sources with a total activity of 6.8 milliCi (actual) in a box calibrated for Saturday, 8/27/16, at noon. The RSO has been in touch with [common carrier] since September 3, 2016 when GE's customer service became concerned while routinely performing package tracking. [The common carrier] last had positive tracking for this package in San Francisco, CA on August 28th. [The common carrier] is still conducting visual surveys in San Francisco and Sydney in an attempt to locate the box and has no evidence to indicate the materials have been delivered to an outside entity. Surveys conducted at O'Hare Airport in Chicago where the package was initially offered for transport were negative. [The common carrier] reports that it is still conducting searches and has put a 'world wide tracer' into effect to locate the material as it still believes it is within their delivery system."
Illinois Event: IL 16007
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

"On 9/26/16 at approximately 1845 EDT, investigation of an identified water leak on one of the two Unit 3 HPCI turbine exhaust drains to the drain pot determined that there was through wall leakage of approximately 2 drops per minute. Operations promptly declared the HPCI system inoperable and entered Technical Specification 3.5.1 Condition C for HPCI being inoperable. Other standby systems (Reactor Core Isolation Cooling and low pressure emergency core cooling systems) are operable.
"HPCI is a single train system. Therefore, per NUREG-1022, this condition is being reported pursuant to 10 CFR 50.72(b)(3)(v)(D) as a condition that could have prevented the fulfillment of the safety function of a system required to mitigate the consequences of a design event.
"This condition has been entered into the corrective action program (IR 2720241). Investigation of the exact flaw location is in progress so that repairs can be made.
"The NRC resident has been informed of this notification." | |
