Dear Mr. Daniels:

On March 3 1, 201 8, the U.S. Nuclear Regulatory Commission (NRC) completed its quarterly inspection under Inspection Manual Chapter 2561, "Decommissioning Power Reactor Inspection Program," at the permanently shutdown Vermont Yankee Nuclear Power Station (VY). On-site inspections were performed on March 12-15, 201 8. 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 you a nd other members of the VY staff on April 16, 201 8, and are described in the enclosed report.

No findings of safety significance were identified.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, 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

EXECUTIVE SUMMARY

Entergy Nuclear Operations, Inc.

Vermont Yankee Nuclear Power Station NRC Inspection Report No. 05000 271/201 8 0 0 1 An announced quarterly inspection was completed at Vermont Yankee Nuclear Power Station (VY) on March 31 , 201 8. O n-site inspection s were conducted on March 12-15, 201 8. 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 decommissioning status. 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 shutdown 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

1 Inspection Report No. 05000271/201 8 00 1

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) 6 0801, 62801, 71801] The inspector performed an on-site inspection on March 12-15, 201 8. 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 reviewed Entergy's 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 (CFH) 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 in the past year in order to verify SFP chemistry parameters were within the limits of Entergy's license commitments. The inspector also reviewed data from the spent fuel pumps to verify that the system was operating within the expected parameters with no negative trends.

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 also met with VY management and discussed staffing levels, how routine maintenance and emergent work is requested, prioritized, and scheduled, and 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 the status of activities related to the site decommissioning to verify activities are in accordance with licensed requirements. The inspector reviewed the decommissioning schedule to verify the schedule is consistent with post shutdown decommissioning activities report (PSDAR).

2 Inspection Report No. 05000271/201 8 00 1

b. Observations and Findings

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 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 the maintenance backlog is reviewed by site management on a regular basis.

The inspector noted the main decommissioning activity is the dry cask loading campaign which is scheduled to be completed in 2018. The inspector verified the schedule is consistent with the April 12, 2017 notification by Entergy changing the schedule in the PSDAR.

c. Conclusions

Based on the results of this inspection, no findings of safety significance were identified.

3.0 Exit Meeting Summary On April 16, 201 8, the inspector presented the inspection results, via teleconference, to Corey Daniels, Director, Nuclear Decommissioning

, and other members of Entergy's staff. The inspector confirmed that proprietary information was not removed from the site.
