Dear Mr. Wamser:
On December 31, 2015, 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 October 26
-29, and December 1
-3, 2015. 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 Coley Chappell, Licensing Manager, and other members of the VY staff on January 20, 2016, 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(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

EXECUTIVE SUMMARY
Entergy Nuclear Operations, Inc.
Vermont Yankee Nuclear Power Station NRC Inspection Report No. 05000 271/20150 10 An announced quarterly inspection was completed at Vermont Yankee Nuclear Power Station (VY) on December 3 1, 2015. O n-site inspection s were conducted on October 26
-2 9 , and December 1-3 , 2015. 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, plant modifications, and decommissioning performance.
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.
1 Inspection Report No. 05000271/2015010 C:\Users\ajk\Documents\LDPR-28.2015010.docx
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 "Post Operation Transition Phase" of decommissioning as described in IMC 2561.
2.0 Post Operation Transition Phase Performance and Status Review
a. Inspection Scope
(Inspection Procedures (IPs) 37801, 608 01 , 71801) The inspector performed on
-site inspection s the week s of October 2 6-2 9 , and December 1-3 , 2015. 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 the programs for the safe wet storage of spent fuel and verified that maintenance was being performed within the established frequencies and that the equipment was being properly maintained. The inspector performed a walk
-down of the spent fuel pool (SFP), service water pumps, and fuel pool cooling heat exchangers to determine the material condition of the SFP and associated systems used to support SFP cooling
. The inspector reviewed the current status and future plans for radioactive water management at the site. The inspector performed a walk
-down of various water tanks and water intrusion locations, reviewed current inventories, tank capacities, and groundwater intrusion rates. The inspector reviewed work orders and execution plans for activities taken to mitigate groundwater intrusion.
The inspector reviewed the project to place the B.5.b pump at a fixed location with pre
-connected piping. The inspector performed a walk
-down of the B.5.b pump placement , interviewed personnel, and observed work in
-progress. The inspector reviewed engineering change (EC) packages, condition reports , and work orders to determine if the B.5.b pump permanent placement project would fulfill its function.
2 Inspection Report No. 05000271/2015010 C:\Users\ajk\Documents\LDPR-28.2015010.docx The inspector reviewed the project to channel spent fuel assemblies. The inspector interviewed personnel, observed spent fuel assemblies being moved from the spent fuel racks into the fuel prep machine, channels being placed on the fuel assemblies, and the fuel assemblies being returned to the spent fuel racks. The inspector reviewed plans, work orders, and condition reports to verify activities were performed in accordance with plant procedures, technical specifications (TS), and final safety analysis report (FSAR).
b. Observations and Findings
The inspector verified that safe wet storage of spent fuel wa s implemented adequately. The inspector verified that the maintenance and surveillance program for systems and components had been conducted in accordance with the TS requirements and established procedures.
The inspector determined that radioactive water inventories were increasing due mainly to the intrusion of groundwater at the site. The inspector verified that the water inventory is tracked daily , that the groundwater intrusion rate has slowed considerably, and that the site has excess tank capacity. The inspector determined that VY is considering options regarding disposal of on
-site radioactive water inventory and is also considering options for future action to further mitigate groundwater intrusion.
The inspector verified the B.5.b pump placement and pre
-connected piping was completed and testing of the pump was satisfactory. The inspector also verified that the ECs were performed in accordance with site procedures and safety reviews had been performed adequately.
The inspector determined the channeling activities were performed safely and met the TS and FSAR requirements. The inspector noted the channeling activities were performed to ensure the fuel assemblies would meet requirements for transportation which would take place at a future date.
c. Conclusions
Based on the results of this inspection, no findings of safety significance were identified.
