Event Notification Report for August 15, 2016

TECHNICAL SUPPORT CENTER OUT OF SERVICE DUE TO FACILITY UPGRADE

"This is a non-emergency eight hour notification for a loss of Emergency Assessment Capability.

"The Technical Support Center (TSC) was removed from service on 08/15/2016 at 1030 [EDT] for a scheduled facility upgrade project, which will improve the overall functionality of the facility. The duration of the upgrade is expected to be 26 days.

"This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii), as the TSC will be unavailable for greater than 72 hours.

"In the event of an emergency, McGuire's alternate TSC will be used while the TSC is upgraded. During this period, the alternate TSC will be staffed and activated using existing emergency planning procedures.

"The Emergency Response Organization team has been notified that the TSC will be unavailable during the upgrade and to report to the alternate TSC in the event of an emergency. This upgrade does not affect the health and safety of the public or station employees. The NRC Resident Inspector has been notified."

SALT SERVICE WATER SYSTEM DECLARED INOPERABLE

"On Monday, August 15, 2016 at 1552 [EDT], with the reactor at [about] 70 percent core thermal power (CTP), Pilgrim Nuclear Power Station (PNPS) entered a 24-hour shutdown Limiting Condition for Operation Action Statement (LCO-AS) for Salt Service Water (SSW) inlet temperature exceeding the Technical Specification (TS) limit in TS 3.5.B.4. The LCO-AS was subsequently exited at 1651 hours when the temperature of SSW trended to below the TS limit.

"Under certain design conditions, the SSW system is required to provide cooling water to various heat exchangers such as the Reactor Building Closed Cooling Water (RBCCW) and Turbine Building Closed Cooling Water (TBCCW) systems. When the inlet temperature to these supplied loads exceeds the 75 degrees F limit established in the TS, the SSW system is conservatively declared inoperable until the temperature trends below this value. This condition existed for approximately 60 minutes.

"The SSW temperature is being closely monitored and trended on a continuous basis.

"This event has no impact on the health and safety of the public.

"The licensee has notified the NRC Senior Resident Inspector.

"This notification is being made in accordance with 10 CFR 50.72(b)(3)(v)(B) and 10 CFR 50.72(b)(3)(v)(D) due to an event or condition that could have prevented fulfillment of a safety function.

"The licensee will be notifying the Commonwealth of Massachusetts Emergency Management Agency."

DAMAGED MOISTURE DENSITY GAUGE

While at a construction jobsite at Kenai Airport, a technician using a Troxler moisture density gauge observed a large equipment grader approaching in reverse mode. The technician retreated from the area and the gauge was run over by the grader. Personnel roped off the damaged gauge area and proceeded to monitor for any contamination. The gauge is a Troxler, Model 3440; S/N 37310; Sources: Cs-137 (8 mCi) and Am-241/Be (44 mCi).

* * * UPDATE FROM ERYN JONES TO VINCE KLCO ON 8/16/2016 AT 1348 EDT * * *

The licensee placed the damaged gauge into an over pack container loaded with sand and transported the damaged gauge to a local office permanent storage facility. The storage area is barricaded and is being monitored. The licensee is consulting with the manufacturer for final damaged gauge disposition.

OFFSITE NOTIFICATION

"On 8/12/16 at 1356 CDT, an ISFSI security officer noticed that two male children were walking west on the railroad tracks on the south end of the OCA, approximately 50 yards onto the property. The children appeared to be between 7 and 10 years of age. The children, presumably upon noticing Security's presence, then ran northeast and back towards the beach fence line. It appeared that the children somehow left the property through the east fence line back onto the beach. Industrial Security and shift RP tech began vehicle and foot patrols to search for the children and ensure that they did, in fact, leave the property. The children were not seen again.

"In accordance with 49 CFR 1580.105 - Reporting Significant Security Concerns, at 1520 on 8/15/16, the Radioactive Waste Group supervisor contacted the designated Transportation Safety Administration inspector to discuss the trespassing incident from 8/12/16. After the discussion with the inspector, the Radwaste supervisor was informed to contact the Department of Homeland Security Freedom Center and provide details of the incident. This contact was made at 1540 on 8/15/16.

"The notification is being made in accordance with 10 CFR 50.72(b)(2)(xi) notification to offsite government agency."

The licensee has notified the NRC Resident Inspector.

IRRADIATOR SAFETY EQUIPMENT FAILURE

The NIST (National Institute of Standards and Technology) irradiator has several Cs-137 sources used to calibrate instruments. During a calibration process, a 3.6 Ci source did not return to its shielded position. The event occurred in a portion of the building where such events are expected, therefore there were no health or safety consequences to employees, public or the environment. Licensee corrective actions include manually installing a lead plug into the beam port (opening) of the irradiator. The licensee is contacting the manufacturer in order to assist with troubleshooting and repairs. The irradiator (Model 81-12; JL Shepherd; S/N 7132) is currently in a safe and stable configuration. It is noted that the irradiator is NOT a Part 36 irradiator.

AGREEMENT STATE REPORT - DAMAGED FIXED GAUGE

The following information was received from the State of New Jersey by email:

"Event Narrative: During a walkthrough of the facility, the night shift RSO [Radiation Safety Officer] discovered that an ABB Industrial Systems, Ltd model LS100 fixed measuring gauge had fallen off of a coal feeder to which it was attached. The area, which is not normally accessed by staff, was cordoned. Readings were taken directly on top of the device, and measured 0.5 to 1.0 mR/h. The device does not have a shutter mechanism. The direct beam was surrounded with lead that was available for shielding.

"Root cause(s) and contributing factors: Vibration from coal feeder caused the metal mounting bracket to shear. Semiannual preventative maintenance did not identify the issue. Scaffolding is required to reach the gauge for maintenance, which makes it difficult to do more regularly.

"Isotope and activity; manufacturer, model and serial number: Ra-226, 0.5 mCi, ABB Industrial Systems, Ltd model LS100, serial number R868."

New Jersey Incident Number: C612607

* * * UPDATE FROM JOE POWER TO STEVEN VITTO AT 1357 EDT ON 09/14/2016 * * *

The following was received from the State of New Jersey via email:

"On September 14, 2016, a 30-day written report from BL England Generating Station was received by NJDEP [New Jersey Department of Environmental Protection]. This report outlined the corrective actions and the current status of the gauge. As a corrective step, BL England updated their maintenance schedule to include more frequent checks of their gauges. The device has been secured on a lead plate, and staged in a labeled 55-gallon steel drum to be disposed of at a later date when disposal of other site sources is scheduled. It will remain in storage under lock and key until that time. The licensee's next inspection will include a review of the implanted changes.

"This incident can be closed."

NMED incident Number: 160359.
