Dear Mr. Boyle:
On March 31, 2017, the U.S. Nuclear Regulatory Commission (NRC) completed its quarterly inspection under Inspection Manual Chapter 2561, Decommissioning Power Reactor Inspection Program," at the permanently shut down Vermont Yankee Nuclear Power Station (VY). On-site inspections were performed on January 29 - February 1, 2017. In-office reviews of information supplied by Entergy Nuclear Operations, Inc. were also performed during the inspection period. 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 inspector, interviews with personnel, and a review of procedures and records. The results of the inspection were discussed with Corey Daniels, Senior Manager - Production, and other members of the VY staff on April 24, 2017, and are described in the enclosed report. No findings of safety significance were identified.
In accordance with 10 CFR 2.390 of the NRCs "Rules of Practice," a copy of this letter, its enclosure(s), and your response, will be made available electronically for public inspection in the NRC Public Document Room or from the NRC document system (ADAMS), accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the Public without redaction.

EXECUTIVE SUMMARY
Entergy Nuclear Operations, Inc.
Vermont Yankee Nuclear Power Station NRC Inspection Report No. 05000271/2017001
An announced quarterly inspection was completed at Vermont Yankee Nuclear Power Station (VY) on March 31, 2017. On-site inspections were conducted on January 29 - February 1, 2017. In-office reviews of information supplied by Entergy Nuclear Operations, Inc. (Entergy)were also performed during the inspection period. The inspection included a review of spent fuel pool (SFP) safety, maintenance and surveillance, and groundwater mitigation activities.
The inspection consisted of observations by the inspector, interviews with Entergy personnel, a review of procedures and records, and plant walk-downs. The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in Inspection Manual Chapter (IMC) 2561, Decommissioning Power Reactor Inspection Program."
Based on the results of this inspection, no findings of safety significance were identified.
Inspection Report No. 05000271/2017001
REPORT DETAILS
1.0 Background
On January 12, 2015, VY certified the permanent removal of fuel from the reactor vessel
[Agencywide Document and Access Management System (ADAMS) Accession No.
ML15013A426]. This met the requirements of 10 Code of Federal Regulations (CFR)50.82(a)(1)(i) and 50.82(a)(1)(ii). On January 20, 2015, the NRC notified VY that the Operating Reactor Assessment Program would cease on January 24, 2015 and that implementation of the Decommissioning Power Reactor Inspection Program would begin on January 25, 2015 (ADAMS Accession No. ML15020A482). VY is currently in the SAFSTOR phase of decommissioning as described in IMC 2561.
2.0 SAFSTOR Performance and Status Review
a. Inspection Scope
[Inspection Procedures (IPs) 60801, 62801, 71801]
The inspector performed an on-site inspection on January 29 - February 1, 2017. In-office reviews of information supplied by Entergy were also performed during the inspection period. The inspection consisted of observations by the inspector, interviews with Entergy personnel, a review of procedures and records, and plant walk-downs.
The inspector accompanied plant personnel on a walk-down of key safety systems, structures and components (SSCs) important to the defueled condition of the plant.
During the walk-down, the inspector evaluated housekeeping and the material condition of the SSCs and assessed area radiological conditions and radiological access controls, including posting and labeling. The inspector observed preparations for the replacement of torus water treatment vessels which maintain water quality for the SFP make-up water supply. The inspector also met with VY management and discussed staffing levels, how routine maintenance and emergent work is requested, prioritized, and scheduled, and reviewed the current maintenance workload. The inspector reviewed the backlog of maintenance work to assess the age and prioritization of the items. The inspector reviewed the maintenance rule program and procedures, as well as the performance criteria and monitoring procedures of systems and components.
The inspector reviewed Entergys programs for the safe wet storage of spent fuel. The inspector performed a walk-down of the SFP and associated support systems to assess material condition, configuration control, and system operation. The inspector toured the control room and interviewed certified fuel handlers (CFHs) to verify SFP system instrumentation, alarms and leakage detection monitoring is adequate to assure the safe storage of spent fuel. The inspector interviewed employees and reviewed SFP chemistry sample analysis that Entergy had performed between January 2016 and January 2017 in order to verify chemistry parameters were within the limits of Entergys license commitments. The inspector also reviewed data from the service water system to verify that the system was operating within the expected parameters with no negative trends.
Inspection Report No. 05000271/2017001 The inspector reviewed current work activities related to the mitigation of groundwater in-leakage in the turbine building. The inspector toured the lower level of the turbine building and observed and interviewed employees performing activities to seal the turbine floor matte. The inspector also reviewed work orders, procedures and plans for sealing the turbine floor matte. The inspector performed a walk-down of the frac storage tanks used to store the groundwater.
b. Observations and Findings
The inspector verified that all systems that supported spent fuel safety continued to be appropriately scoped in to the maintenance rule and that the performance criteria established were acceptable. The inspector verified that the maintenance and surveillance program for systems and components had been conducted in accordance with the technical specification requirements and established procedures. The inspector noted during the plant walk-down that housekeeping and plant material condition standards were being maintained. The inspector determined that workers followed work plans, surveillance procedures, and industrial safety protocols and were aware of job controls specified in work instructions. The inspector determined that the maintenance backlog is reviewed by site management on a regular basis.
The inspector determined that Entergy was safely storing spent fuel in wet storage. The inspector verified SFP chemistry and cleanliness controls were being adequately implemented. The inspector verified surveillance requirements for water level and temperature of the SFP were adequate and procedures provided guidance to restore SFP water level if required. The inspector also verified the CFH rounds were adequate to satisfy the associated technical specification requirements for the SFP.
The inspector verified that groundwater in-leakage continues to be a high priority for Entergy management and efforts to mitigate the intrusion of groundwater are continuing.
The inspector verified that the water inventories are tracked daily and that VY is continuing disposal of groundwater intrusion inventory by shipping the water offsite.
c. Conclusions
Based on the results of this inspection, no findings of safety significance were identified.
