The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations, and the conditions of your license. The inspection consisted of observations by the inspectors, interviews with personnel, and a review of procedures and records. The results of the inspection were discussed with William Bartron, Licensing Supervisor, and other members of your staff on August 19,2013, via telephone, at the conclusion of the inspection; and are described in the enclosed report. No findings of safety significance were identified.
Current NRC regulations and guidance are included on the NRC's website at wwtrv.nrc.qov; select Nuclear Materials; Med, Ind, & Academic Uses; then Regulations, Guidance and Gommunications. The current Enforcement Policy is included on the NRC's website at www.nrc.qov; select About NRC, Organizations & Functions; Office of Enforcement; Enforcement documents; then Enforcement Policy (Under'Related Information'). You may also obtain these documents by contacting the Government Printing Office (GPO) toll-free at 1-866-512-1800. The GPO is open from 8:00 a.m. to 5:30 p.m. EST, Monday through Friday (except Federal holidays). Please contact Laurie Kauffman (610-337-5323) if you have any questions regarding this matter.

EXECUTIVE SUMMARY
Dominion Nuclear Connecticut, lnc.
Millstone Power Station Unit 1 NRC lnspection Report No. 0500024512013009 A routine announced safety inspection was conducted on June 4 - 5, 2013 and July 30 - August 2,2013 at MS-1. The inspection included a review of operations and management oversight, maintenance, corrective action program (CAP) implementation, fire protection, and plant support activities while in safe storage (SAFSTOR) status. The inspection consisted of observations by the inspectors, interviews with Dominion personnel, and a review of procedures and records. The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in Inspection Manual Chapter (tMC) 2561, "Decommissioning Power Reactor lnspection Program."
There are currently no ongoing decommissioning activities being conducted at MS-1.
Based on the results of this inspection, no findings of safety significance were identified.

REPORT DETAILS
1.0 Background MS-1 is located in the town of Waterford, Connecticut. MS-1 was a single cycle, boiling water reactor with a thermal output of 2011 megawatts and a net electrical output of 652.l megawatts. The plant went into commercial operation on December 28, 1970 and permanently ceased operations on July 17, 1998. Subsequently, the fuel was permanently removed from the reactor vessel and is currently stored in the spent fuel pool (SFP). MS-1 is in SAFSTOR and Dominion plans to actively decommission MS-1 in parallel with the decommissioning of the operational units after they have been permanently shut down.
The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in IMC 2561.
2.0 Safe Storage (SAFSTOR) Performance and Status Review a. lnspection Scope (lnsoection Procedures (lPs) 36801, 37801. 40801. 60801. 62801.

A routine announced safety inspection was conducted on June 4 - 5, 2013 and July 30 - August 2,2013 at MS-1. The inspection consisted of observations by the inspectors, interviews with Dominion personnel, and a review of procedures and records.
The inspectors reviewed the SAFSTOR program as outlined in the Defueled Safety Analysis Report (DSAR), Technical Specifications (TS), and Technical Requirements Manual (TRM) and assessed the adequacy of management oversight of SAFSTOR responsibilities for the MS-1 facility. Specifically, the inspectors reviewed the decommissioning management and staff organization and Dominion's implementation of SAFSTOR activities related to safe storage of radioactive material. The inspectors discussed any design changes or modifications since the previous inspection and reviewed the material condition of MS-1 facilities during plant tours of the reactor building, the fuel handling floor, and the radioactive waste building.
The inspectors reviewed the quarterly surveys of the standby shutdown heat exchanger room and the maintenance and surveillance tests for the SFP cooling pumps and motors; the decay heat removal pumps, fans, and motors; the ventilation fans and motors; and the emergency diesel generator to verify that work was being performed within the established frequencies and that the equipment was being properly maintained.
The inspectors also reviewed activities and documentation associated with the following SAFSTOR programs: occupational exposure, fire protection, radioactive effluent control, and site radiological environmental monitoring program (REMP). The inspectors reviewed radioactive gaseous and liquid effluent release permits, the annual REMP report, and the annual effluent report, which included a summary of the radioactive waste management and transportation programs. The inspectors reviewed radioactive waste and transportation documents related to dry active waste generated from MS-1.

On July 30 - August2,2013, the inspectors observed in-situ measurements of neutron absorber material in spent fuel pool racks. The in-situ measurement test is also known as "Boron Areal Density Gauge for Evaluating Racks" (BADGER) testing. The inspectors observed Dominion's contractor perform equipment preparations, such as set up and calibration, and portions of the BADGER testing. The inspectors reviewed procedures and documentation related to the BADGER testing.
The inspectors reviewed CAP condition reports associated with MS-1 to determine if issues were being properly identified, evaluated, and prioritized. The inspectors also reviewed NRC Event Notification Number 49175, "Unit 1 Spent Fuel Pool lsland Radiation Monitor Inoperable," dated July 6, 2013.
Observations and Findinqs The inspectors noted that there were no personnel changes within the Dominion organization related to the SAFSTOR activities and confirmed that the staff was adequately implementing SAFSTOR activities. The inspectors reviewed one design modification related to improving the longevity of the SFP pumps and decay heat removal pumps. The inspectors verified that the maintenance and surveillance program for systems and components had been conducted in accordance with thd TS and TRM requirements and established procedures. The inspectors noted that no significant water intrusion was evident and the material condition of components had remained unchanged in the reactor building, the fuel handling floor, and the radioactive waste building since the previous inspection. The inspectors also confirmed that no dismantlement or decommissioning activities were performed since the previous inspection.
ln June 2011, Dominion had contracted a vendor to conduct BADGER testing on specific spent fuel racks in the SFP. During an NRC inspection conducted on July 11 - 13,2011, the inspectors noted that the final test results were not yet available and would be reviewed during a subsequent inspection. In August 2011, Dominion generated CAP Condition Report (CR) 436420 to report that the final test results from the June 20'11 BADGER test were inconclusive and that a subsequent BADGER test would be required to adequately assess the condition of the spent fuel racks. On July 30 - August 2, 2013, the inspectors observed Dominion's contractor perform BADGER testing. The results of the BADGER test were not available prior to the conclusion of this inspection.
The annual radiological effluent and the annual REMP reports demonstrated that all calculated doses were below regulatory dose criteria of 10 CFR 50, Appendix l. The inspectors noted that radioactive waste was not shipped for offsite disposal since the last inspection.
The inspectors determined that issues were entered into the CAP, prioritized, and evaluated commensurate with their safety significance. Corrective actions were implemented to address identified issues and were being tracked to closure using the CAP.
