PLANNED TESTING OF STACK RADIATION MONITORS
"Millstone Unit 2 loss of assessment capability due to pre-planned maintenance of the Millstone Station stack radiation monitor RM-8169 at 1335 EDT on 7/17/13. This event is reportable pursuant to 10 CFR 50.72(b)(3)(xiii) as any event that results in a major loss of emergency assessment capability. During the maintenance, Unit 2 was at 100% power, Mode 1. We informed the State of Connecticut, Waterford dispatch, and the NRC Resident Inspector."

MOISTURE GAUGE SHUTTER STUCK IN OPEN POSITION
"TVA's Paradise Fossil Plant uses a coal scan moisture monitor with a sealed source containing 3 millicuries of Cesium-137. The gauge is used to monitor the moisture in the coal being transferred on a common feed line to three units at Paradise Fossil Plant. On July 17, 2013 at 1030 CDT, the shutter on the moisture gauge was determined not to be operable. The shutter failed in the open position. The shutter failure discovery was made during the six month shutter test. The issue is being entered into the corrective action program. No personnel radiation exposure was received. The source is not shuttered, but the gauge is in the operating position and is in a safe condition.
"A twenty-four hour notification is required per 10 CFR 30.50(b)(2) due to failure of the moisture monitor shutter to close.
"NRC Region II Duty Officer and NRC Region I Duty Officer will be notified."
Gauge model TBM-201.
Licensee stated that there is no danger of personnel exposure.

OFFSITE NOTIFICATION DUE TO A CHEMICAL SPILL ONSITE
"Today, July 17th, 2013, at approximately 1605 EDT, the New Jersey Department of Environmental Protection was notified that approximately 1 pint of sodium hypochlorite was spilled onto the lands of the State of New Jersey. The spill has been contained and cleaned-up. There was no actual or potential impact on the environment and no impact on the health and safety of the public or onsite personnel.
"Due to notification of a government agency, this event is being reported under 10CFR50.72 (b)(2)(xi)."
The spill did not reach the federal reportable quantities limit.
The licensee has notified the NRC Resident Inspector.

SALT SERVICE WATER SYSTEM DECLARED INOPERABLE
"On Wednesday, July 17, 2013 at 1054 hours EDT, with the reactor at 100% core thermal power (CTP) the Pilgrim Nuclear Power Station (PNPS) entered a 24-hour shutdown Limiting Condition for Operation (LCO) for Salt Service Water (SSW) inlet temperature exceeding the Technical Specification (TS) limit in TS 3.5.B.4. The LCO was subsequently exited at 1625 hours when the temperature of SSW trended to below the TS limit.
"Under certain accident conditions the SSW system is required to provide cooling water to the Reactor Building Closed Cooling Water (RBCCW) system heat exchanger. When the inlet temperature to this supplied load exceeds the 75 [degrees] F limit established in the TS, the SSW system is declared inoperable until the temperature trends below this value. This condition existed for approximately 5-1/2 hours and the SSW system was declared operable and the LCO exited. A maximum temperature of 75.5 [degrees] F was recorded during this period.
"At 1230 hours a power reduction was conducted to improve secondary plant parameters and Rx power is currently 85%.
"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." The licensee will notify the Commonwealth of Massachusetts.
