During containment spray pump inservice testing the minimum flow recirculation line recorded negative flow indicating reverse flow in the line. After the troubleshooting, it was determined that a degraded minimum flow check valve was allowing a path to the refueling water storage tank (RWST) for certain post loss of coolant accident (LOCA) conditions. The minimum flow isolation has been closed to eliminate the path. No actuation occurred during this time.
The NRC Resident Inspector, Connecticut Department of Energy and Environmental Protection (DEEP) Hartford, and Watertown Dispatch have been notified.

The following report was received from the New York State Department of Health via facsimile:
"On 7/2/15, at 1330 EDT, the Radiation Safety Officer (RSO) of Applus RTD USA Inc., called the New York State Department of Health to report that they had a source disconnect of an industrial radiography camera at a temporary jobsite in Wellsville, New York. They were taking images of a pipeline using an QSA Global Model: 880 Delta with an 80 curie Iridium source. The radiography team secured the area by extending the barricades and keeping 100% visual surveillance of the area. Applus RTD is not approved per the license to perform source retrieval. Applus contracted with another NYS licensee authorized to perform the source retrieval. Applus's RSO and the retrieval personnel arrived on site at 1715 EDT and the source was secured at 1815 EDT.
"According to the RSO, no person of the general public was ever in danger of receiving a dose above the legal limits."

"This telephone notification is provided in accordance with Exelon Reportability manual SAF 1.10, 'Major Loss of Emergency Preparedness Capabilities', and 10CFR50.72(b)(3)(xiii).
"On July 8th 2015 at 1837 [CDT], it was determined that the onsite Technical Support Center (TSC) Ventilation System Supply Fan belts had failed, resulting in loss of ventilation for the facility. Repairs were not completed within the time required had the TSC needed to be staffed. There is currently no emergency event in progress requiring TSC staffing. If an emergency is declared and the TSC ERO [Emergency Response Organization] activation is required, the TSC will be staffed and activated unless the TSC becomes uninhabitable due to ambient temperatures, radiological, or other conditions. If relocation of the TSC staff becomes necessary, the Station Emergency Director will relocate the staff to an alternate TSC location in accordance with applicable site procedures.
"The licensee has notified the [NRC] Senior Resident Inspector of the issue."

"At 0710 CDT on July 10, 2015, Exelon was notified by the siren vendor that siren CL27 experienced a communications failure during the daily test. Siren CL27 affects 33.9% of the Clinton EPZ population. The loss of communications represents more than 25% of the EPZ population and is therefore reportable under 10 CFR 50.72(b)(3)(xiii).
"The siren vendor is currently investigating to repair the issue.
"The DeWitt County Emergency Manager has been notified. DeWitt County has implemented the backup means of notification called 'Route Alerting' in lieu of siren communications. Route Alerting consists of vehicles and public address systems.
"The NRC Senior Resident has been notified.
"1300 - Siren returned to service." |

"At 1810 [EDT], the Salem unit 1 control room received an alarm that a CO2 discharge occurred in the Diesel Fuel Oil Transfer Pump Rooms on the 84 foot elevation in the Auxiliary Building. The control room referred to the OHA [Overhead Annunciator] response procedure S1.OP-AR.ZZ.0001 for OHA A-8, 'Fire Prot CO2/Halon Disch.' The ARP [Alarm Response Procedure] directed implementation of the S1.OP-AB.Fire-0001 procedure and control room ventilation was shifted to the 'fire outside' mode of operation. The on site fire protection team responded to the area and confirmed the CO2 discharge. The [on site] fire department determined that there was no fire and no smoke in the area of the discharge. The Fire Brigade Liaison inspected the equipment and determined that there was no adverse impact to any equipment located in the vicinity of the discharge and no operational impact on the plant.
"All systems responded as expected.
"There were no personnel injuries as a result of the discharge.
"Atmosphere in the area of the discharge has been verified normal and no restrictions to the area are in place."
The cause of the discharge was determined to be a faulty detector. No off site response was requested and an hourly firewatch will be initiated until the detector is repaired.
The licensee will notify the NRC Resident Inspector and has notified the states of Delaware and New Jersey.
Notified DHS, FEMA Operations Center, and NICC and e-mailed Nuclear SSA and FEMA National Watch Center.
