Dear Mr. Shea:

On December 31, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an

inspection at your Sequoyah Nuclear Plant, Units 1 and 2. On January 13, 2014, the NRC

inspectors discussed the results of this inspection with Mr. Carlin and other members of your

staff. Inspectors documented the results of this inspection in the enclosed inspection report.

NRC inspectors documented one self-revealing finding of very low safety significance (Green) in

this report. This finding involved a violation of NRC requirements. The NRC is treating this

violation as a non-cited violation (NCV) consistent with Section 2.3.2.a of the NRC Enforcement

Policy.

If you contest the violation or significance of this NCV, you should provide a response within 30

days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear

Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001; with

copies to the Regional Administrator, Region II; the Director, Office of Enforcement, U.S.

Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident

Inspector at the Sequoyah Nuclear Plant.

If you disagree with a cross-cutting aspect assignment in this report, you should provide a

response within 30 days of the date of this inspection report, with the basis for your

disagreement, to the Regional Administrator, Region II, and the NRC Resident Inspector at the

Sequoyah Nuclear Plant.

As a result of the Safety Culture Common Language Initiative, the terminology and coding of

cross-cutting aspects were revised beginning in calendar year (CY) 2014. New cross-cutting

aspects identified in CY 2014 will be coded under the latest revision to Inspection Manual

Chapter (IMC) 0310. Cross-cutting aspects identified in the last six months of 2013 using the

previous terminology will be converted to the latest revision in accordance with the cross-

reference in IMC 0310. The revised cross-cutting aspects will be evaluated for cross-cutting

themes and potential substantive cross-cutting issues in accordance with IMC 0305 starting with

the CY 2014 mid-cycle assessment review.

SUMMARY

IR 05000327/2013-005, 05000328/2013-005; 10/1/2013 - 12/31/2013; Sequoyah Nuclear Plant,

Units 1 and 2; Other Activities

The report covered a three-month period of inspection by resident inspectors and announced

inspections by regional inspectors. One self-revealing finding was identified. The significance

of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual

Chapter (IMC) 0609, "Significance Determination Process," (SDP) dated June 2, 2011. Cross-

cutting aspects are determined using IMC 0310, Components Within the Cross-Cutting Areas,

dated October 28, 2011. The NRC's program for overseeing the safe operation of commercial

nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4,

dated December 2006.

A.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

Green: A self-revealing non-cited violation of 10 CFR 50 Appendix B, Criterion XVI,

Corrective Action, was identified for the licensees failure to promptly correct a

condition adverse to quality within a reasonable time. Timely corrective actions were not

taken to correct a dual position indication (open and closed lights both illuminated) on

the Unit 1 A train residual heat removal (RHR) containment sump suction flow control

valve (FCV) 1-FCV-63-72. This licensee entered this issue into the corrective action

program as problem evaluation report (PER) 772193 and performed repairs to the valve

to restore the system to operable status.

This finding was determined to be more than minor because it was associated with the

Design Control attribute of the Mitigating Systems cornerstone and adversely affected

the cornerstones objective to ensure the availability, reliability, and capability of systems

that respond to initiating events to prevent undesirable consequences (i.e., core

damage). Specifically, the finding reduced the reliability and capability of the A train

RHR system to perform its safety function as designed. The finding required a detailed

risk analysis as the A RHR system was inoperable beyond its allowed outage time of 72

hours. The detailed risk analysis concluded that the finding was of very low safety

significance (Green). This finding was determined to have a cross-cutting aspect

relating to the proper classification, prioritization, and evaluation of operability and

reportability of conditions adverse to quality in the Corrective Action component of the

Problem Identification and Resolution area. P.1(c) (Section 4OA5)

1R06 Flood Protection Measures

.1

Internal Flooding

a.

Inspection Scope

The inspectors examined internal flood protection measures associated with the 1A and

1B safety injection (SI) pump rooms internal flood design in order to verify that flood

mitigation plans were consistent with the design requirements and risk analysis

assumptions. The inspectors verified that equipment essential for reactor shutdown was

properly protected from a flood caused by pipe breaks in the 1A & 1B SI pump room.

Specifically, the inspectors reviewed the licensees moderate energy line break flooding

study to fully understand the licensees flood mitigation strategy, reviewed licensee

drawings and then verified that the assumptions and results remained valid. The

inspectors walked down the 1A & 1B SI pump room to verify the assumed flooding

sources, adequacy of common area drainage, and flood detection instrumentation to

ensure that a flooding event would not impact reactor shutdown capabilities. The

inspectors completed one sample.

1R20 Refueling and Other Outage Activities

.1

Unit 1 Refueling Outage Cycle 19

a.

Inspection Scope

For the Unit 1 refueling outage that began on October 14, 2013, the inspectors

evaluated licensee activities to verify that the licensee considered risk in developing

outage schedules, followed risk reduction methods developed to control plant

configuration, developed mitigation strategies for the loss of key safety functions, and

adhered to operating license and TS requirements that ensure defense-in-depth. The

inspectors also walked down portions of Unit 1 not normally accessible during at-power

13

Enclosure

operations to verify that safety-related and risk-significant SSCs were maintained in an

operable condition. Specifically, between October 14 and November 21, the inspectors

performed inspections and reviews of the following outage activities. Documents

reviewed are listed in the Attachment. The inspectors completed one sample.

Outage Plan. The inspectors reviewed the outage safety plan and contingency plans

to confirm that the licensee had appropriately considered risk, industry experience,

and previous site-specific problems in developing and implementing a plan that

assured maintenance of defense-in-depth.

Reactor Shutdown. The inspectors observed the shutdown in the control room from

the time the reactor was tripped until operators placed it on the RHR system for

decay heat removal to verify that TS cool down restrictions were followed. The

inspectors also toured the lower containment as soon as practicable after reactor

shutdown to observe the general condition of the reactor coolant system (RCS) and

emergency core cooling system components and to look for indications of previously

unidentified leakage inside the polar crane wall.

Licensee Control of Outage Activities. On a daily basis, the inspectors attended the

licensee outage turnover meeting, reviewed PERs, and reviewed the defense-in-

depth status sheets to verify that status control was commensurate with the outage

safety plan and in compliance with the applicable TS when taking equipment out of

service. The inspectors further toured the main control room and areas of the plant

daily to ensure that the following key safety functions were maintained in accordance

with the outage safety plan and TS: electrical power, decay heat removal, spent fuel

cooling, inventory control, reactivity control, and containment closure. The

inspectors also observed a tag-out of the B Train CCP system to verify that the

equipment was appropriately configured to safely support the work and testing. To

ensure that RCS level instrumentation was properly installed and configured to give

accurate information, the inspectors reviewed the installation of the Mansell level

monitoring system. Specifically, the inspectors discussed the system with

engineering, walked it down to verify that it was installed in accordance with

procedures and adequately protected from inadvertent damage, verified that Mansell

indication properly overlapped with pressurizer level instruments during pressurizer

drain-down, verified that operators properly set level alarms to procedurally required

set-points, and verified that the system consistently tracked RCS level while lowering

to reduced inventory conditions. The inspectors also observed operators compare

the Mansell indications with locally-installed ultrasonic level indicators during entry

into reduced inventory conditions.

14

Enclosure

Refueling Activities. The inspectors observed fuel movement at the spent fuel pool

and at the refueling cavity in order to verify compliance with TS and that each

assembly was properly tracked from core offload to core reload. In order to verify

proper licensee control of foreign material, the inspectors verified that personnel

were properly checked before entering any foreign material exclusion (FME) areas,

reviewed FME procedures, and verified that the licensee followed the procedures.

To ensure that fuel assemblies were loaded in the core locations specified by the

design, the inspectors independently reviewed the recording of the licensees final

core verification.

Reduced Inventory and Mid-Loop Conditions. Prior to the outage, the inspectors

reviewed the licensees commitments to Generic Letter 88-17. Before entering

reduced inventory conditions the inspectors verified that these commitments were in

place, that plant configuration was in accordance with those commitments, and that

distractions from unexpected conditions or emergent work did not affect operator

ability to maintain the required reactor vessel level. Mid-loop conditions were not

entered during this outage since SG eddy current testing was not required.

Heat-up and Start-up Activities. The inspectors toured the containment prior to

reactor startup to verify that debris that could affect the performance of the

containment sump had not been left in the containment. The inspectors reviewed

the licensees mode-change checklists to verify that appropriate prerequisites were

met prior to changing TS modes. To verify RCS integrity and containment integrity,

the inspectors further reviewed the licensees RCS leakage calculations and

containment isolation valve lineups. In order to verify that core operating limit

parameters were consistent with core design, the inspectors also examined portions

of the low power physics testing surveillance.

RADIATION SAFETY (RS)

Cornerstones: Occupational Radiation Safety (OS) and Public Radiation Safety (PS)

2RS1 Radiological Hazard Assessment and Exposure Controls

a.

Inspection Scope

Hazard Assessment and Instructions to Workers: During facility tours, the inspectors

directly observed labeling of radioactive material and postings for radiation areas, high

radiation areas (HRAs), and airborne radioactivity areas established within the

radiologically controlled area (RCA) of the Unit 1 containment, Unit 1 and Unit 2 auxiliary

buildings, Independent Spent Fuel Storage Installation (ISFSI), and radioactive waste

(radwaste) processing and storage locations. The inspectors independently measured

radiation dose rates or directly observed conduct of licensee radiation surveys for RCA

areas in the Unit 1 containment, Unit 1 and Unit 2 Auxiliary buildings, and ISFSI. The

inspectors reviewed survey records for several plant areas including surveys for alpha

emitters, airborne radioactivity, and pre-job surveys for selected Unit 1 Refueling Outage

19 (U1R19) tasks. The inspectors also discussed changes to plant operations that could

contribute to changing radiological conditions since the last inspection and reviewed

U1R19 crud burst results and post crud burst dose rate surveys. For selected U1R19

outage jobs, the inspectors attended, or reviewed, pre-job briefings and radiation work

permit (RWP) details to assess communication of radiological control requirements and

current radiological conditions to workers. Selected U1R19 work activities included Unit

1 control rod drive mechanism duct work, Unit 1 Refueling Activities, Unit 1 Head O-ring

Surface Work & Inspection, and work in the Unit 1 Equipment Pit and transfer canal.

Hazard Control and Work Practices: The inspectors evaluated access barrier

effectiveness for selected Unit 1 and Unit 2 Locked High Radiation Area (LHRA) and

Very High Radiation Area (VHRA) locations. Changes to procedural guidance for LHRA

and VHRA controls were discussed with health physics (HP) supervisors. Controls and

their implementation for storage of irradiated material within the spent fuel pool (SFP)

were reviewed and discussed in detail. Established radiological controls (including

airborne controls) were evaluated for selected U1R19 tasks including refueling and

reactor cavity work activities, work in auxiliary building HRAs, and radwaste processing

and storage. In addition, licensee controls for areas where dose rates could change

significantly as a result of plant shutdown and refueling operations were reviewed and

discussed.

Occupational workers adherence to selected RWPs and HP technician (HPT)

proficiency in providing job coverage were evaluated through direct observations and

interviews with licensee staff. Electronic dosimeter (ED) alarm set points and worker

stay times were evaluated against area radiation survey results for refueling and reactor

cavity work. ED alarm logs were reviewed and worker response to dose and dose rate

alarms during selected work activities was evaluated. For HRA tasks involving

significant dose rate gradients, e.g. reactor head O-ring work, the inspectors evaluated

the use and placement of whole body and extremity dosimetry to monitor worker

exposure.

19

Enclosure

Control of Radioactive Material: The inspectors observed surveys of material and

personnel being released from the RCA using small article monitor, personnel

contamination monitor, and portal monitor instruments. The inspectors reviewed the last

two calibration records for selected release point survey instruments and discussed

equipment sensitivity, alarm set points, and release program guidance with licensee

staff. The inspectors compared recent 10 CFR Part 61 results for the Dry Active Waste

(DAW) radioactive waste stream with radionuclides used in calibration sources to

evaluate the appropriateness and accuracy of release survey instrumentation. The

inspectors also reviewed records of leak tests on selected sealed sources and discussed

nationally tracked source transactions with licensee staff.

Problem Identification and Resolution: PERs associated with radiological hazard

assessment and control were reviewed and assessed. The inspectors evaluated the

licensees ability to identify and resolve the issues in accordance with procedure NPG-

SPP-22.300, Corrective Action Program, Rev. 0. The inspectors also evaluated the

scope of the licensees internal audit program and reviewed recent assessment results.

Radiation protection activities were evaluated against the requirements of UFSAR

Section 12; TS Sections 6.8 and 6.12; 10 CFR Parts 19 and 20; and approved licensee

procedures. Licensee programs for monitoring materials and personnel released from

the RCA were evaluated against 10 CFR Part 20 and IE Circular 81-07, Control of

2RS8 Radioactive Solid Waste Processing and Radioactive Material Handling, Storage, and

Transportation

a.

Inspection Scope

Waste Processing and Characterization: During inspector walkdowns, accessible

sections of the liquid and solid radwaste processing systems were assessed for material

condition and conformance with system design diagrams. Inspected equipment included

radwaste storage tanks; resin transfer piping, resin, and filter packaging components;

and abandoned boric acid evaporator equipment. The inspectors discussed component

function, processing system changes, and radwaste program implementation with

licensee staff.

The radionuclide characterizations for 2010, and 2012, for selected waste streams were

reviewed and discussed with Radwaste/Transportation staff. For primary resin, reactor

coolant system filters, and DAW, the inspectors evaluated analyses for hard-to-detect

nuclides, reviewed the use of scaling factors, and examined quality assurance

comparison results between licensee waste stream characterizations and outside

laboratory data. Waste stream mixing and concentration averaging methodology for

resins and filters was evaluated and discussed with Radwaste/Transportation staff. The

20

Enclosure

inspectors also reviewed the licensees procedural guidance for monitoring changes in

waste stream isotopic mixtures. The 10 CFR 61 analysis results were also discussed

with Chemistry personnel.

Radioactive Material Storage: During walkdowns of indoor and outdoor radioactive

material storage areas, the inspectors observed the physical condition and labeling of

storage containers and the posting of Radioactive Material Areas. The inspectors also

reviewed licensee procedural guidance for storage and monitoring of radioactive

material.

Transportation: The inspectors observed a shipment of vendor equipment during the

week of inspection. The inspectors reviewed shipping procedure requirements and

discussed preparation of shipping documents, package marking and labeling, and

interviewed shipping technicians regarding Department of Transportation (DOT)

regulations.

Selected shipping records were reviewed for consistency with licensee procedures and

compliance with NRC and DOT regulations. The inspectors reviewed emergency

response information, DOT shipping package classification, waste classification,

radiation survey results, and evaluated whether receiving licensees were authorized to

accept the packages. Licensee procedures for handling shipping containers were

compared to Certificate of Compliance requirements and manufacturer

recommendations. In addition, training records for selected individuals currently

qualified to ship radioactive material were reviewed.

Radwaste processing activities and equipment configuration were reviewed for

compliance with the licensees Process Control Program and UFSAR, Chapter 11.

Waste stream characterization analyses were reviewed against regulations detailed in

10 CFR Part 20, 10 CFR Part 61, and guidance provided in the Branch Technical

Position on Waste Classification (1983). Radioactive material and waste storage

As required by IP 71152, the inspectors performed a review of the licensees corrective

action program and associated documents to identify trends that could indicate the

existence of a more significant safety issue. The inspectors review was focused on

repetitive equipment issues, but also included licensee trending efforts and licensee

human performance results. The inspectors review nominally considered the twelve-

month period of January 2013 through December 2013, although some examples

expanded beyond those dates when the scope of the trend warranted. Specifically, the

inspectors considered the results of daily inspector screening discussed in Section

4OA2.1 and reviewed licensee trend reports for the period in order to determine the

existence of any adverse trends that the licensee may not have previously identified.

Documents reviewed are listed in the Attachment. The inspectors completed one

(Closed) Unresolved Item (URI) 050000327/2013004-01, Water Intrusion into Actuator of

Valve 1-FCV-63-72

a.

Inspection Scope

The inspectors opened this URI as a result of water intrusion into the actuator of 1-FCV-

63-72, which is the A train containment sump suction for the Unit 1 A RHR train. This

issue was noted during an operability inspection conducted last quarter. The inspectors

determined more inspection was required in order to resolve the issue. On August 8,

2013, an operator noted the valve exhibited dual indication and on August 14, a related

valve, 1-FCV-74-3, failed its periodic stroke test. The following day, 1-FCV-63-72 was

noted to be failed as well due to a large of amount of water buildup in the actuator. A

subsequent root cause of the failure was completed during this inspection period and

concluded the water intrusion was due to groundwater which migrated through the wall

of the RHR valve vault room and into the valve conduit. Although the circumstances

regarding the water intrusion may have been beyond the licensees ability to predict, the

24

Enclosure

inspectors noted there were opportunities before August 14 to identify and correct the

deficient condition. Thus, the inspectors identified the following non-cited violation

(NCV) as discussed below. Documents reviewed are listed in the Attachment.

b.

Findings

Introduction: A self-revealing Green NCV of 10 CFR 50 Appendix B, Criterion XVI,

Corrective Action, was identified for the licensees failure to correct a condition adverse

to quality within a reasonable amount of time. Timely corrective actions were not taken

to correct a dual position indication (open and closed lights both illuminated) on the Unit

1 A train RHR containment sump suction flow control valve 1-FCV-63-72.

Description: On August 8 at 0709, the Unit 1 control room operator noted that valve 1-

FCV-63-72 showed dual position indication on the control board. This valve is the A

train RHR suction valve from the reactor containment sump and is normally closed,

showing only a single position indication lamp on the control board. Valve 1-FCV-63-72

was verified to be locally closed. No other activities were noted that would have caused

the valve to come off its closed seat. Initial troubleshooting for the dual indication

consisted of: 1) a visual inspection of the valve; 2) a visual inspection of the motor

control center (MCC) cubicle during an attempted closure of the valve; 3) a review of the

wiring diagram by a troubleshooting team; 4) replacement of the MCC light indicating

bulb; and 5) a visual inspection of the main control room (MCR) hand switch. Based on

the troubleshooting teams analysis of the wiring diagrams, no impact was expected on

the interlocks associated with 1-FCV-63-72. The team initially concluded that the most

likely cause of the indication was a short circuit in the control power indication in the

MCR valve hand switch. Based on this conclusion, plus the fact that the valve is not

normally stroked at power (due to concerns of accidently transferring borated water from

the RWST to the containment sump), the licensee chose not to immediately stroke test

1-FCV-63-72. Instead, the licensee declared the position indication for the valve

inoperable per Post Accident Monitoring requirements as delineated in TS 3.9.1. This

was a 30 day limiting condition for operation. The licensee then began development of a

troubleshooting plan which would require more intrusive troubleshooting of the issue

starting the following week.

On August 14 at 2315, during a routine quarterly inservice testing valve stroke activity,

valve 1-FCV-74-3 failed to stroke in the closed direction from the control room. This

valve is the A train RHR suction valve from the RWST and is normally open. Valve 1-

FCV-74-3 was immediately declared out of service and the 72-hour Emergency Core

Cooling Systems (ECCS) TS 3.5.2 action statement was entered. During

troubleshooting, operators attempted to close valve 1-FCV-74-3 remotely from the MCC

cubicle. This action blew control power fuses. The licensee then attempted local

manual operation and noted 1-FVC-74-3 could be manually closed without binding.

Valve 1-FCV-74-3 was partially manually closed and then reopened from the MCC

without incident. Due to the relationship between valves 1-FCV-63-72 and 1-FCV-74-3

(interlocks, shared wiring in junction boxes, etc.) the licensee suspected that the failure

of valve 1-FCV-74-3 to close and valve 1-FCV-63-72 dual position indication were

related.

25

Enclosure

The licensee subsequently opened the 1-FCV-63-72 actuator and noted that a

significant amount of water had accumulated inside the actuator. This water caused

significant electrical shorting in the valve control circuit and rendered the valve

inoperable. Also, the water affected valve 1-FCV-74-3, as this valve utilizes contacts

from valve 1-FCV-63-72 circuitry. It was noted that a low current short caused the failure

of the closing coil for valve 1-FCV-74-3. Following repairs to both 1-FCV-63-72 and

1-FCV-74-3, the ECCS system was returned to operable status on August 17 at 0200.

The licensees past operability determination concluded that 1-FCV-63-72 and 1-FCV-

74-3 were likely inoperable beginning on August 8 when 1-FCV-63-72 was noted to have

a dual indication. Thus the A train ECCS system was most likely inoperable for

approximately nine days, which exceeded the TS allowable outage time. On October

21, 2013, Licensee Event Report 50-327/2013-003 was submitted as a result of this

issue. The licensee concluded that the source of the water was ground water that had

migrated through the concrete ceiling that housed the valve and actuator cables. The

ground water leaked through the threaded penetration seal and inside the conduit and

flowed down into the valve actuator. During the most recent Unit 1 refueling outage in

November 2013, the licensee redesigned the conduit penetration to prevent the intrusion

of moisture into the conduit. The licensee noted the rate of moisture intrusion was most

likely higher in the recent months due to a higher than normal amount of rainfall that

temporarily raised the water table in the vicinity of the plant. The inspectors also noted

that on February 29, 2012, the licensee discovered water buildup in the actuator of 1-

FCV-63-72. This deficiency was entered into the CAP; however it appears that this

precursor was not adequately evaluated such that continued water intrusion ultimately

led to the failure noted on August 8, 2013.

Analysis: The licensees failure to take timely actions to correct a condition adverse to

quality was a performance deficiency. The inspectors concluded that testing and

inspection could have determined that valve 1-FCV-63-72 was inoperable much earlier

than August 14 when it was noted that RHR suction valve to the RWST, 1-FCV-74-3, did

not pass its routine surveillance test. This finding was determined to be more than minor

because it was associated with the Design Control attribute of the Mitigating Systems

cornerstone and adversely affected the cornerstones objective to ensure the availability,

reliability, and capability of systems that respond to initiating events to prevent

undesirable consequences (i.e., core damage). Specifically, the finding reduced the

reliability and capability of the A train RHR system to perform its safety function as

designed. Using IMC 0609.04, Initial Characterization of Findings, dated June 19,

2012, and IMC 0609, Appendix A, Exhibit 4 - External Events Screening Questions,

dated June 19, 2012, the finding required a detailed risk analysis as the A RHR system

was inoperable beyond its TS-allowed outage time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The detailed risk

analysis concluded that the finding was of very low safety significance (Green).

A Phase 3 analysis was performed by the regional Senior Reactor Analyst to determine

the impact of the finding. The analysis assumed a recoverable failure of the 1-FCV-63-

72 valve, along with a dependent failure of the 1-FCV-74-3 valve. The major impacts

were in the swapover from the RWST to the containment sump as the source of water to

26

Enclosure

mitigate medium and smaller LOCA sequences. Because of the low exposure time, the

availability of the opposite train, and the ability of the operations staff to operate the

effected valves manually, the finding was determined to be Green.

The cause of this finding was determined to have a cross-cutting aspect relating to the

proper classification, prioritization, and evaluation of operability and reportability of

conditions adverse to quality in the Corrective Action component of the Problem

Identification and Resolution area, in that, on February 29, 2012, the licensee discovered

water buildup in the actuator of 1-FCV-63-72 and did not adequately evaluated the

condition adverse to quality such that continued water intrusion ultimately led to the

failure noted on August 8, 2013. P.1(c)

Enforcement: Title 10 of the Code of Federal Regulations Part 50, Appendix B, Criterion

XVI, Corrective Action, requires, in part, that measures shall be established to assure

that conditions adverse to quality, such as failures, malfunctions, deficiencies,

deviations, defective material and equipment, and non-conformances are promptly

identified and corrected. Contrary to the above, from August 8 through August 17, 2013,

the licensee failed to assure that a condition adverse to quality, the failure of valve FCV-

63-72, was corrected in a timely manner. Specifically, the licensee failed to sufficiently

evaluate and correct a moisture intrusion problem associated with the RHR containment

suction motor-operated valve. Corrective actions taken by the licensee included

redesigning and modifying the conduit penetration to prevent the intrusion of moisture

into the conduit. The violation was entered into the licensees CAP as PER 772193.

Quarterly Resident Inspector Observations of Security Personnel and Activities

a.

Inspection Scope

During the inspection period, the inspectors conducted observations of security force

personnel and activities to ensure that the activities were consistent with licensee

security procedures and regulatory requirements relating to nuclear plant security.

These observations took place during both normal and off-normal plant working hours.

These quarterly resident inspector observations of security force personnel and activities

did not constitute any additional inspection samples. Rather, they were considered an

integral part of the inspectors normal plant status review and inspection activities.

Review of the Operation of an Independent Spent Fuel Storage Installation (ISFSI)

(60855.1)

a.

Inspection Scope

The inspectors performed a walkdown with the field operator of the ISFSI storage pad on

December 26, 2013, to verify that operations were conducted in a safe manner in

accordance with approved procedures and without undue risk to the health and safety of

the public. The inspectors noted that there were 40 multi-purpose canisters (MPCs)

positioned on the ISFSI pad. The inspectors verified the MPC vents were in good

condition and free of obstruction. The inspectors also verified natural circulation within

the MPCs. The inspectors verified that any ISFSI problems were placed in the CAP.

The inspectors also reviewed ISFSI document control practices to verify that changes to

the required ISFSI procedures and equipment were performed in accordance with

guidelines established in local procedures and 10 CFR 72.48. Documents reviewed are

listed in the Attachment.

b.

Findings

No findings were identified.

Shipping Records and Radwaste Data

Two Design Change Notices were reviewed and both have been accomplished. The first

moved Radwaste liquid processing from the railroad bay into the drumming room that was in

effect at the start of the period which included back to November 2010 and the second

established a lift system to be used for the steam generator replacement in 2012 with a closure

date of 8/13/2013.

The licensee provided several drawings delineating abandoned equipment. The inspector

chose the abandoned boric acid evaporator system to review.
