Plant Support and Radiological Controls The licensee has provided adequate controls to limit exposures of workers to external sources of radiation. Pre-job briefings were thorough and adequately covered radiological conditions and actions to take in the event of high radiation levels. High radiation area work activities were effectively controlled. Posting and labeling of radioactive materials and radiation areas continued to meet regulatory requirements.

Radioactive waste material shipments made by the licensee were in compliance with regulatory requirements.

DNC effectively implemented their security program for compliance with the May 23, 2002, Order for Interim Compensatory Measures for safeguards and security for Millstone Unit 1. No findings of significance were identified.

iii REPORT DETAILS I. Operations and Decommissioning Status O1 Conduct of Operations O1.1 Spent Fuel Pool Safety a. Inspection Scope (60801)

The inspector reviewed the condition and operational status of equipment and components important to the safe storage of spent fuel. The inspection consisted of tours of plant areas, visual observation of plant equipment and interviews with cognizant personnel.

b. Observations The inspector toured the facility with the Unit 1 Project Supervisor and verified that components and equipment important to the safe storage of spent fuel were operable and adequately maintained. Material condition of plant equipment and building areas was adequate with noted improvement from the previous inspection. The inspector noted that the licensee had implemented several measures to prepare the spent fuel pool island for SAFSTOR conditions.

A decay heat (DH) system for spent fuel pool (SFP) cooling consisting of redundant circulation pumps and necessary piping to interconnect the system with existing plant piping had been installed. A recently installed makeup system consisting of a 5000 gallon-capacity makeup tank and makeup pump along with the necessary interconnecting piping can provide makeup water to the spent fuel pool. The inspector noted that one of the existing SFP cooling pumps had been replaced with a newer model, equipped with mechanical seals. The second SFP cooling pump had previously been equipped with new mechanical seals. The inspector observed work activities in the vicinity of the spent fuel pool and noted that activities were adequately controlled. No safety concerns were identified.

c. Conclusions The licensee maintained an effective program to ensure the availability and reliability of equipment and components important to the safe storage of spent fuel. Recent efforts to implement the spent fuel pool island configuration were adequate.

O1.2 Station Freeze Protection Program a. Inspection Scope (71714)

The inspector evaluated the licensees preparations to maintain the operability of systems and equipment identified as important to the safe storage of spent fuel, during the cold weather season. The inspection consisted of tours of plant areas, interviews with cognizant personnel and reviews of licensee procedures relating to cold weather preparations.

b. Observations The inspector toured the facility with the cognizant supervisor and verified that heat trace equipment was energized where required and space heaters were appropriately stationed and operable. The inspector reviewed procedure OP 2268, Cold Weather Preparation and Operation and procedure OP 213, Cold Weather Preparations. The inspector noted that the licensee had performed procedure OP 2268 prior to the cold weather season and verified that equipment required to be operable during cold weather conditions in support of safe storage of spent fuel was operable. The licensee procedural checklist also identified equipment located within the drywell that was not visually inspected by the inspector. The inspector confirmed that any discrepancies noted by the licensee during the performance of OP 2268 were appropriately addressed.

The inspector noted that procedure OP 213 contained several checklist items relating to Unit 1 cold weather preparations. These items were not included in the OP 2268 checklist. Both procedures were revised in May 2003 in response to a condition report and as part of the effort to transition control of Unit 1 activities to Unit 2. The licensee subsequently identified the need to develop a site-wide, cold weather preparation, common operating procedure. This initiative is ongoing and when completed will allow the licensee to delete OP 213. The additional cold weather preparation items contained in OP 213 were completed by the licensee on December 11, 2003 with the exception of one item requiring the cycling of various system drain valves to drain any residual water that may be present. This item was completed on January 7, 2004.

The inspector did not identify any safety concerns associated with the additional checklist items.

c. Conclusions The licensee established an adequate program to maintain operability of systems and components, identified as important to the safe storage of spent fuel, during the cold weather season.

O1.3 Spent Fuel Material Accountability Control and Accounting at Nuclear Power Plants a. Inspection Scope Temporary Instruction(TI) 2515/154 The inspection consisted of interviews with cognizant personnel and review of licensee procedures relating to spent fuel accountability and control.

b. Observations This temporary instruction (TI) evaluates licensees material control and accountability (MC&A)

programs for spent fuel rods separated from parent fuel assemblies. The TI requires the inspector to determine if the licensee has ever removed irradiated fuel rods from an assembly, or has ever reconstituted fuel assemblies. This effort is referred to as Phase I of the TI. If a licensee has performed such activities, then Phase II of the TI is performed. Phase II consists of several questions to be answered to evaluate the effectiveness of the licensees MC&A program. Prior events at Millstone Unit 1 resulted in the issuance of the subject TI. Since Millstone Unit 1 has removed irradiated fuel rods from parent assemblies in the past, Phase II

of the TI is applicable to Millstone Unit 1. The licensee has established programs to address spent fuel material control and accountability. The inspector interviewed the cognizant engineer responsible for the spent fuel MC&A program. The inspector noted that procedures MP-13-SNM-PRG, Millstone Special Nuclear Material Control and Accountability Program and MC-5, Special Nuclear Material Inventory and Control, and other licensee documents address the items contained in Attachment A - Phase II of the TI. The completion of Phase II activities will be performed during a subsequent inspection.

c. Conclusions Millstone Unit 1 falls within the scope of the TI 2515/154, Spent Fuel Material Accountability Control and Accounting at Nuclear Power Plants, requiring the completion of Phase II activities.

II. Plant Support and Radiological Controls R1 Radiological Protection Controls R1.1 Occupational Exposure Controls a. Inspection Scope (83750)

The inspector reviewed the licensees program to determine the capability to monitor and control radiation exposure to employees and to determine adequacy of the licensees radiation protection program. The inspection consisted of observations of field activities, interviews with cognizant personnel and inspection of radiological postings.

b. Observations The inspector observed that areas of the Radiologically Controlled Area (RCA) were appropriately posted and labeled for radioactive material. Portal monitors and frisking instruments were located in the RCA for use by workers. Both beta and gamma-sensitive portal monitors were provided at the primary RCA exit location. Equipment was noted to be operable and adequately maintained. High radiation areas and technical specification locked high radiation areas were properly posted and locked as required. The inspector noted that radiological postings were readily visible, well maintained and adequately reflected radiological conditions in the posted areas.

The inspector observed entry by a work crew into a technical specification locked high radiation area. A work crew supervisor coordinated the entry and performed an adequate briefing prior to workers entering the area. Health Physics personnel maintained effective key control during the entry and provided appropriate radiological coverage.

The inspector observed a pre-job briefing for a work activity to be conducted in the spent fuel pool area. The task involved the pre-operational testing of a debris collection device to be used during grid segmentation work. There were 25 attendees at the pre-job briefing. The project coordinator utilized a pre-job checklist during the briefing and adequately addressed radiological and safety aspects of the task along with foreign material exclusion (FME) controls, communications, and self-checking techniques. The Health Physics representative provided a

detailed overview of the radiation work permit (RWP) requirements and radiological conditions associated with the task. No safety concerns were identified.

c. Conclusions The licensee has provided adequate controls to limit exposures of workers to external sources of radiation. Pre-job briefings were thorough and adequately covered radiological conditions and actions to take in the event of high radiation levels. High radiation area work activities were effectively controlled. Posting and labeling of radioactive materials and radiation areas continued to meet regulatory requirements.

R1.2 Radioactive Waste Management and Transportation a. Inspection Scope (86750)

The inspector reviewed selected records of radioactive waste shipments made during this inspection period to determine compliance with NRC and Department of Transportation (DOT)

regulations.

b. Observations The inspector reviewed records for four radioactive waste shipments made in September -

October 2003. These shipments included control rod blades, fission chambers and local power range monitors (LPRMs). The inspector reviewed package dose rate survey data, radioactive material labeling, total activity, nuclide characterization, hazard waste classification, 10CFR61 documentation, and final truck survey data. Documentation was in compliance with appropriate regulatory requirements. No safety concerns were identified.

c. Conclusions Radioactive waste material shipments made by the licensee were in compliance with regulatory requirements.
