EXECUTIVE SUMMARY Maine Yankee Atomic Power Company NRC Inspection Report 50-309/97 08 This integrated inspection included aspects of licensee operations, engineering, maintenance, and plant support. The report covers a three-month period of resident inspection; in addition, it includes the results of an announced inspection by regional physical security inspectors.
Operations The reactor plant and spent fuel pool cooling systems were placed in the desired condition for the upcoming months. Maine Yankee initiated actions to analyzo and prepare for cold weather. Maintenance activities were completed and heating systems were functioning properly. The inspector did not identify any further areas of concern for cold weather. (Cection 01.1 and 2.1)
Maintenance Pre-evolution planning and appropriate edlological oversight resulted in the successful removal of the incore instruments. This evolution, which had potentially significant radiological consequences, was performed safely and in accordance with the procedure. (Section M1.1)
Initial oversight of site characterization activities by Maine Yankee was weak. The
-
stop work imposed by Maine Yankee was appropriate to assure minor issues were adequately addressed and corrected. Communication issues were addressed and Maine Yankee personnel were assigned responsibility to monitor the site characterization. Issues identified by outside parties and agencies were being documented and addressed. Environmental sampling was being conducted in accordance with the procedures. (Section 2.1)
Enaineerina The spent fuel pool heat up test was an appropriate verification nf the spent fuel pool heat-up rate. The procedure was well written and was properly approved. The test was performed and data was recorded as required by the procedure. (Section E2.1)
A weak procedure, poor procedure adherence, and inadequate planning for the capsulo removal resulted in the evolution taking over twice as long as required.
However, due to the relatively low dose rates in the work area the additional radiation exposure was not significant. The radiological controls and oversight implemented by heal.% physics were excellent and resulted in the completion of the job with no exposure or contamination concerns. (Section E2.2)

The audit of health physics was a notable effort by Maine Yankee to identify and prevent issues similar to those which occurred at a similar f acility undergoin0 decommissioning. The audit was thorough end the issues were appropriately accepted for resolution. (Section R7.1)
The staffing of the emergency response organization has been adequately managed and maintained throughout the reduction of personnel at Maine Yankee. A training drill was an effective tool to assure new personnel were familiar with their positions and emergency plan procedures. (Section P5.1)
The inspectors determined that, except for the violation associated with the detection sids, the licensee was conducting its security and safeguards activities in a manner that protected public h9alth and safety. The Security Program, as implemented, met the licensee's commitments end NRC requirements. (Section S)
The falsification of fire watch rounds was determined to be a result of improper implementation of the fire protection plan by Maine Yankee. The lack of procedures for the implementr.tlon of compensatory fire watch rounds is a violation of NRC requirements. (Section F4.1)

Report Details i
I Summary of Plant Stalug Throughout the inspection period Maine Ye kee remained in the decommissioning mode.
At tiv@s during the period focused on safe maintenance of the spent fuel, reorganization of he facBy staff, revision of site procedures, including technical specifications and the emt gency plo, and performance of the site characterization, l. Ooerations
' onduct of Operations 01.1 general Comments (71707)
i Using Inspection procedure 71707,the inspector conducted reviews of ongoing i
plant operations. Several major activities were completed to put the plant in the i
condition desired for the upcoming months. The spent fuel pool rerack project was
!
stopped, and the final condition was analyzed es acceptable. Primary component cooling water was restored as the normal ecoling supply to the spent fuel pool hem exchanger. The temporary secondary component cooling water hoses were removed. The inco.e radiation detection instrumentation was removed, the upper guide structure was installed, and the reactor head was set In place. The refueling cavity was drained and the fuel transfer canal blank flange was installed.
Operational Status of Facilities and Equipment 02.1 (Closed! t.ER 97-05 Cold Weather Prenarations a.
Insoection Scope (717141 Tha inspector reviewed the preparation 9 made by Maine Yankee for cold weather.
The inspector also independently toured the facility to look for areas of concern,
'
b.
Observations and Findinas With the plant in the shutdown condition, the heat generation within the facility is greatly reduced. Because the spent fuel poolIsland has not yet been developed, Maine Yankee intends to heat the entire facility this winter. To assure proper Implementation of tne cold weather preparations, a senior member of the operations department was assigned as a lead and focal point of the project. As a result of brainstorming sessions,54 issues were Identified. These issues 'nere tracked and the resolutions were documented.- As of November 18,1997, all but eight actions were completed. The remaining items, several of which were efficiency improvements, were being tracked and were manageable.

The auxiliary heating system at Maine Yankee uses oil burning boilers to produce steem. The steam is routed to radiators throughout the plant. Prior to the onset of cold weather, Maine Yan' tee performed maintenance activities to prepare the auxikary boilers and steam heating system for winter.
>
One area of concern was the containment building. Freezing in the containment building could result in freezing and damage to the fuel transfer canal, which is a spent fuel pool boundary. To address this concern Maine Yankee will heat the containment using the normal containment heating unit. l.. sine Yankee has estimated that the installec heater has adequate capacity to preclud1 freezing.
d Several areas within containment are monitored for temperature by the plant
,
computer. The computer readings and alarm:. can be read by the operators in the control room. Additionally, Maine Yankee is preparing to install a blank flange on the spent fuel pool end of the transfer canal. This flange will prevent the tube from fillisq with water and will further eliminate the risk due to freezing.
A previous area of concern in cold weather was the intake structure. Licensee Event Report (LER) 97 05 reported the potential for freezing due to a loss of power during extreme cold periods. Although this potential still exists, the consequences are greatly reduced with the plant shutdown and defueled. The heat up rate of the spent fuel pool allows adequate time to address any resultant problems from a loss
'
of power to the intake structure. Additionally, operators monitor temperature on a once per shift basis normally, and once every four hours during periods with
'
temperature less than 20* F. Therefore, LER 97-05 is closed, c.
Conclusion Maine Yankee initiated actions to analyze and prepare for cold weather.
Maintenance activities were completed and heating systems were functioning properly. The inspector did not identify any further areas of concern for cold
'
weather,
Miscelleneous Operations issues 08.1 Review and Closure of Open issutti Previously opened issues related to systems or components no longer required to be maintained in the current plant condition were reviewed.

50-309/93-10-00 LER Surveillance testing of ECCS Subcomponents 08.2 LQ.losed) - Unresolved item 50-309/97-05-07: Failure to meet requirements of 10 CFR 70.24 for new fuel criticality mc nitors.
This issue involved the failure to have in place either a criticdity monitoring system for storage and handling of new (non-irradiated) fuel or an NRC-approved exemption to this requirement contained in 10 CFR 70.24.10 CFR 70.24 requires that each licensee authorized to possess more than a small amount of special nuclear material (SNM) maintain in each area in which such materialis hand:ed, used, or stored a criticality monitoring system which will energize clearly audible alarm signals if accidental criticality occurs. The purpose of 10 CFR 70.24 is to ensure that, if a criticality were to occur during the ha' idling of SNM, personnel would be alerted to that f act and would take appropriate action.
Most nuclear power plant licensees were granted exemptions from 10 CFR 70.24 during the construction of their plants as part of the Part 70 licer'se issued to permit the receipt of the initial core. Generally, these exemptions were not explicitly renewed when the Part 50 operating license was issued, which contained the
.
.
combined Part 50 and Part 70 authority. In August 1981, the Tennessee Valley Authority (TVA), in the course of reviewing the operating licenses for its Browns Ferry facilities, noted that the exemption to 10 CFR 70.24 that had been granted during the construction phase had not been explicitly granted in the operating license. By letters dated August 11,1981, and August 31,1987, TVA requested an exemption from 10 CFR 70.24. On May 11,1988, NRC informed TVA that "the previously issued ex6mptions are stillin effect even though the specific provisions of the Part 70 licenses were not incorporated into the Part 50 license."
Notwithstanding the correspondence with TVA, the NRC has determined that, in cases where a licensee recolved the exemption as part of the Part 70 license issueo during the construction phase, both the Part 70 and Part 50 licenses should be examined to determine the status of the exemption. The NRC view now is that unless a licensee's licensing basis specifies otherwise, an exemption expires with the expiration of the Part 70 license. The NRC intends to amend 10 CFR 70.24 to provide for administrative controls in lieu of criticality monitors.
The NRC has conclud-1 that a violation of 10 CFR 70.24 existed. The NRC has also determined that numerous other licensees have similar circumstances that were caused by confusion regarding the continuation of an exemption to 10 CFR 70.24 originally issued prior to issuance of the Part 50 license. After considering all the factors that resulted in these violations the NRC has concluded that while a violation did exist, it is appropriate to exercise enforcement d scretion for Violations involving Special Circumstances in accordance with Section Vil B.6 of the " General Statement of Policy and Procedures for NRC Enforcement Actions" (Enforcement Policy), NUREG 1600.
08.3 (Closed) LER 93-08-00. Emeraency Core Coolina Svstem (ECCS) Velves Found Unfocked LER 93 08 00, ECCS Valves Found Unlocked, reported 19 valves associated with the service water system that were not locked. This was due to an oversight in the locked valve program, and a 1 of the valves were in the correct positions. The valves were locked and the controlling procedures were revised. The inspector reviewed the service water system alignmer.t and found no discrepancies. This item is closed.
08.4 (Closed) LER 93-12-00. Control Room Ventilation Trains inocerable Due to Preventative Maintenance Maine Yankee reported that quarterly maintenance of the control room ventilation system resulted in both trains of control room ventilation being inoperable for short periods of time. Amendment 146 of the technical specifications was made to accommodate this problem. This LER is close _

Subsequently, violation VIO 50-300/97 03-01, was issued to document similar performance issues. Therefore, IFl 50-309/97-01-01,is closed and corrective actions will be tracked by the above violation.
II. Maintenanc_g, M1 Conduct of Maintenance M1.1 Incore Instrument Removal a.
Insnection Scoce (62707)
In preparation for setting the reactor head back on the vessel, Maine Yankee used maintenance procedure 6-02-4,Incore Detector Removal, to remove the incore radiation detectors. The inspector reviewed the procedure and observed portions of the evolution, b.
Observations and Findinas The incore instruments (ICI's) were used during power operation to map the reaction rates within the core to monitor fuel performance. The first section of the detectors that were exposed to the core were highly irradiated. Af ter approximately 30 feet the contact radiation levels decreased to less that 50 mr/ hour. The removal process maintained the first section of tubing under water in the reactor cavity. The remainder of the tubing, approximately 120 feet, was removed from the water and cut up into drums for disposal. The irradiated detector tips were cut up under water and placed into trash baskets. The trash baskets were transferred to the spent fuel pool for storage pending disposal.
Preparation for this evolution was excellent. Training was conducted which featured slides of actual ICI removals during previous outages. The training covered specific duties, lessons learned, radiological controls, safety concerns, and contingencies. A pre evolution brief was conducted prior to each shift to discuss project status and radiological conditions.
The removal of the detectors was accomplished as planned. The removal required team work between a crane operator, tool handlers, cutter operators, and health physics technicians. Communications were clear and concise. Radiological oversight was appropriate and the job was completed within the estimated dose, c.
Conclusion Pre-evolution planning and appropriate radiological oversight resulted in the successful removal of the incore instruments. This evolution, which had potentially i

-significant radiological consequences, was performed safely and in accordance with the procedure.
M2 Maintenance and Material Condition of Facilities and Equipment M2.1 Site Characterization a.
Inspection Scooe (80721)
In preparation for decommissioning, Maine Yankee was perform:ng a detailed site
,
characterization. This characterization will provide the basis for decommissioning activities and their associated costs. The inspector reviewed the site characterization plan, observed activities in the field, and obtained independent samples for analysis.
,
b.
Observations and Findinas The site characterization was being performed by a contractor. A Site Characterization Plan which describes the characterization process was submitted by the contractor to Maine Yankee and approved. Additionally, procedures used by the contractor were reviewed and approved by Maine Yankee. The site characterization effort was being monitored by several prospective decommissioning contractors. Questions received from all personnelinvolved were being documented and resolved.
The site characterization plan focused on five areas: 1) Environmenta' ladiological Characterization; 2) Radiological Characterization of Surfaces and Sta :tures; 3)
Radiological Characterization of Systems; 4) Hazardous Material C,haracterization Survey; and 5) Background Study Plan. Site characterization work commenced the week of November 3,1997. The contractor started with two teams, an environmental team and a systems team.
The environmental team performed several types of surveys to identify plant related radionuculides in the local environment. Drive-over surveys were performed to look for areas above background. The drive over surveys involved a gamma scan using a plastic scintillator detector. This detector was mounted to a four wheel drive truck, a four wheel drive all terrain vehicle, and in some cases a backpack. A global positioning system (GPS) receiver was used in conjunction with the surveys to mark the locations of the readings. The GPS readings were corrected for the inherent GPS inaccuracies through the use of a stationary receiver at a known location that produces a real time GPS correction factor. The GPS readings and survey data were recorded and stored in a computer.
The drive-over surveys were nearly completed for accessible areas. However, early snowfallin the area prohibited the completion of one area. Areas with e!evated -
readings were marked in the field with surveyors flags and additional analysis wi!!
be performed to determine the cause of the readings. At the close of the inspection, the results of these surveys were still being analyzed.

l A large percentage of the area surrounding the plant is river and mud flats.- At low 4-tide the mud flats are extensive and are used by local residents for digging clams -
and worms. The characterization plan called for samples of the mud flats. An air
boat was used to provide easy access for obtaining samples. Mud samples were
,
I.
-taken on the flats all around the owner controlled area, as well as across the river i
on the banks of Montsweeg Island. initially, samples were only taken to a depth of
+
s!x inches ' Howevert due to questions related to the basis for the six inches, a g
- number of samples will be taken to eighteen inches.
,
In addition to the mud flat samples, sediment samples were taken from the river -
bottom near the discharge diffuser pipe. The discharge diffuser pipe is the effluent path for all normal plant discharg%. As of tho end of this inspection period, the h_
soil, mud, or sediment samples had not been analyzed due to the laboratory preparation and procedures not being completed.-
U The inspector observed a portion of the field sampling and obtained independent samples at several locations. The inspector observed the technicians adequately documenting their surveys and samples and obtaining the samples in accordance
.
with their sampling procedures. The results of the NRC analysis will be compared
- to the licensee results.
.
Systems and structures characterization work was also started. System surveys -
involved opening systems to check the internals for activity. The Maine-Yankee
. work control system was being used to control work on plant systems. Mechanics
- were performing the physical work of opening systems and the contractor was performing the surveys.' At the completion of the surveys, systems required to be -
. functional were being restored and raturned to operations.

Observations and Findinos Procedure 417-23, Spent Fuel Pool Heat Up Rate Test, was developed by Maine Yankee to characterize the heat-up rate of the spent fal pool. This information will then be used as the bases for several engineering evaluations, such as the spent fuel pool island cooling system design and modifications to the emergency plan.
The procedure had two phases, the first being the securing of all spent fuel pool cooling and flow and monitoring the heat-up rate. During this phase pool temperature went from 81' F to 147 F ever a period of 73 hours8.449074e-4 days <br />0.0203 hours <br />1.207011e-4 weeks <br />2.77765e-5 months <br />. During this phase the fuel building ventilation system was kept in service. Data recorded included pool temperature and level, and indoor and outdoor temperatures and humidities.
The second phase of the test maintained the pool at constant temperature to measurs the pool evaporation rate. This data was co!!ected with the pool at 140 F, 130* F,120* F,110* F, and 100* F. Temperature and humidity data was again taken, c.
Conclusion The spent iuct oo',e heat-up test was an appropriate verification of the spent fuel pool heat up rate. The procedure was well written and was properly approved. The test was performed and data was recorded as required by the procedure.

insoection Scone (71707)
To obtain information related to activation of the reactor vessel materials, Maine Yant se elected to pull one of the core material specimen surveillance capsules for analysis. The inspector reviewed procedure 13-26, Recovery of Irradiation Surveillance Capsule, and observed the evolution of pulling the capsule, b.
Observations and Findinos Pulling the capsule was tied to the critical path of activities as a prerequisite for setting the reactor head and for isolating the transfer canal from the refueling cavity to the spent fuel pool. This evolution was of significance because the surveillance capsule was highly activated and had a potential to cause significant radiation exposure if handled improperly. The capsules were installed inside the reactor vessel between the vessel wall and the core shroud. The capsules require a special long handled tool to be threaded onto the capsule to unlatch the built in locking mechanism and allow lifting of the specimen. The evolution was lead by an engineer from the reactor engineering group.
A pre-ev 'Jtion brief Was conducted with all of the participants in the evolution.
Stressing the need to keep the surveillance capsule submerged at all times, the

health physics staff discussed'rediological concems associated with the hb,1
contamination control requirements, and' expected dose rates in the' work area. The Longineer discussed the general' sequence of the procedure.'However, details'of the i
-
! capsule latching mechanism and techniques for retrieval were not discussed.
,
During the first attempt to remove a capsule, the engineer failed to adequately
,
follow the procedure which resulted in the capsule latching mechanism not being.
released, in this case the engineer failed to direct the threading of the tool onto the i
coupler until the resistance of the locking mechanism was met, At this point the -
procedure directed further threading of three and one third turns to unlatch the
!
locking device. The personnel performing the evolution only threaded the tool onto the coupler three and one third turns total and attempted to remove the spec! men.
~ As a result, the lock remained engagad and the force limit was reached without removing se capsule. This error was identified by the inspector and the procedure
.
j:
was stopped and repeated.
{
However, during the second attempt the tool was threaded too far onto the coupler-
,
which caused the lock to over extend and prevent removal of the specimen.
t
. Attempts were made to remove two other specimens prior to stopping the -
i evolution. However, the personnel were within the bounds of the procedure and did not' apply excessive forces in attempts to remove the capsules.
After a discussion with the vendor and review of the drawings, the personnel were able to better understand the manipulation of the lock and the key indications they
.
- were feeling with the tool. The removal of a capsule was subsequently completed
U and transferred to the spent fuel pool without further complication.
.
c.
Conclusion F
A weak procedure, poor procedure adnerence, and inadequate planning for the
capsule removal resulted in the evolution taking over twice as long as required.
L However, due to the low dose rates in the work area the additional radiation
,
'
exposure was not significant.' The radiological controls and oversight implemented by health physics were excellent and resulted in the completion of the job with no
}
exposure or contamination concerns.-

IV. Plant Suooort R7 Quality Assurance in Radiological Protection and Chemistry Activities R7.1 Quality Assurance Audit of Radiation Protection a.
Insoection Scope (40500)
From October 2,1997, through October 9,1997, Maine Yankee quality assurance performed an audit of the radiation protection and radioactive waste programs. The inspector attended the audit team exit meeting and reviewed the audit report, MY-97 03/09.
b.
Observations and Findinos
,
This audit was initiated, in part, because Maine Yankee was concerned with weaknesses identified at t5e Haddam Neck plant in Connecticut. The audit was a good initiative in emphasizing the importance of the health physics department in a decommissioning environment.
The audit team identified twelve issues through the course of the audit. The issues were promptly addressed by health physics management. The issues were entered into the learning bank and apparent causes and corrective actions were developed.
.
Some of the more significant issues identified were inadequacies, inconsistencies, and omissions in procedures and weaknesses in implementing effective corrective actions. Procedure reviews and revisions were ongoing and were scheduled to be completed by the end of the year. The specific issues representing the lack of appropriate corrective actions were individually addressed by Maine Yankee.
However, the issue of the Maine Yankee corrective action program remains an issue. In a separate audit, quality assurance determined that inadequacies in the corrective actions program was a site-wide issue. Maine Yankee initiated a process improvement team and is planning a new corrective actions program in January, c.
Conclusion The audit of health physics was a notable effort by Maine Yankee to identify and prevent issues similar to those which occurred at a similar facility undergoing decommissioning. The audit was thorough and the issues were appropriately accepted for resolutio,-

- As a result of the destaffing, significant changes in the key positions of the emergency response organization (ERO) have occurred. The inspector reviewed the
-
staffing of the ERO and observed a training drill.-
.
b.'
- Observations and Findinas Maine Yankee's current ERO roster consists of two full emergency response teams
and a third team for filling " key" positions only. The licensee is in the process of
,
training individuals'who will be replacing those ERO members that are in the'
j process of retiring and have key positions.- At this time, all but a few have completed the required training.
On October 15,1997, the inspector observed a training drill that enabled the new -
members to practice and gain experience in preparation for their new ERO positions, s
iThe drill scenario featured a dropped fuel bundle which caused fuel damage and a
,
leak in the spent fuel pool liner. The insoector determined that the scenario was appropriate for:the current status of the plant. The emergency response facilities -
were staffed appropriately and the staff followed steps delineated in their emergency response plan and procedures. The inspector noted that the licensee met the objectives of the training exercise and no major deficiencies were identified.
c..
Conclusion
. The EP staff has been very dedicated in ensuring that Maine Yankee meets their I
staffing and training obligations and continue to meet the commitments made in
.their emergency plan and procedures. The NRC inspector noted that training drills were an effective tool for providing hands-on training and determining the effectiveness _of the EP training process.

Observations. Findinas and Conclusion
On October 22,1997, the. inspectors observed licensee testing of the IDSs and determined they were functional and effective, and were installed and maintained as described in the Security Plan. However, it was determined based on discussions
<
with licensee management, documentation reviews, and inspector's observations,
,
that the licensee failed to ensure that the detection aids, used to alert officers in the

, assessment towers, were being maintained and controlled as required in the -
Security Plan.
'
- Specifically, on October 10,1997, an.SFM circumvented the reset button a
associated with the audible alarm in one of the assessment positions. This action

y to the threat, as required by NRC regulations.
b.
Observations and Findinas Observations of CAS and SAS operations verified that the alarm stations were equipped with the appropriate alarm, surveillance, and communication capabilities.
,
Interviews with alarm station operators found them knowledgeable of their duties and responsibilities. The inspectors also verified through observations and interviews that the alarm station operators were not required to engage in. activities that would interfere with the assessment and response functions, and that the
_
licensee had exercised communication methods with the local law enforcement agencies as committed to in the Security Plan.

Qbservations and Findinos
,
The inspectors reviewed the 1997 QA audit of the security program, conducted September 811,1997,(Audit No.97-004). The audit was found to have been conducted in accordance with the Security Plan. To enhance the effectiveness of the audit, the audit team included an independent security specialist. The audit report identified 5 findings. Two of the findings were related to procedure compliance, two were related to proceduralinconsistencies, and one finding addressed human errors related to the control, issuance, and handling of documents. The inspectors determined that the findings were not indicative of programmatic weaknesses.
However, the audit report identifies that a common factor related to all five findings was inattention to detcil. This causal factor is consistent with inspectors observations previously identified in this report.
- The inspectors determined that based on discussions with security management and

F4 Fire Protection Staff Knowledge and Performance F4.1 Falsification of Fire Watch Loas (URI 50-309/97 05-07) Closed a.
Inspection Scope (71750)
The inspector reviewed the investigation and corrective actions taken in response to the falsification of fire watch logs by a temporary Maine Yankee employee. The individual, who was assigned to conduct fire watches, had signed off on some art logs without actually making the required periodic rounds, b.
Observations and Findinas On May 28,1997, Maine Yankee security pt,.sonnel identified that an employee designated to conduct fire watches in various areas of the plant had not been conducting the watches. This was determined when a security offices advind security supervision that the individual had not been seen on rounds for ',ome time.
Reviews of fire watch patrollogs and individual security key card recorc s revealed that at some times, the individual was not actually in some areas contrary to his signature in the logs for those areas. As a result of degraded fire seal barriers, Maine Yankee requires a roving fire watch to enter and inspect eighteen areas of the plant on an hourly basis.
As immediate corrective actions, plant support management instituted a review of fire watch records to verify that there were no obvious problems. They also conducted periodic checks of the fire watch areas to verify that personnel were conducting the required watches. The requirements and significance of conducting the fire watches was re-iterated to all individuals involved in fire watches. Maine Yankee expanded their scope of reviews to include all personnelinvolved with performing fire watches,in order to determine the extent of this discrepancy. as a result of these reviews, Maine Yankee determined that three of the four individuals assigned to perform fire warches had falsified their logs, in response to the identification of the fire watch issues, Maine Yankee terminated the involved employees and placed the fire round responsibilities with security.
These corrective actions eliminated the problems with falsification of logs; however, several subsequent issues such as missed or late rounds were identified. Maine Yankee addressed these issues through increased supervisory oversight and changes to the implementation and tracking process.
The inspector reviewed the fire protection plan and the compensatory action process. The inspector concluded that the Maine Yankee implementation of fire watches as compensatory actions was not being implemented through approved procedures as required by tachnical specifications. Technical specifications, section 5.8.2.f, required written procedwes for fire protection program implementation.
The Maine Yankee procedure,19-5, impairments to Fire Protection Systems, required compensatory measures to be established for impairments to fire protection plan fire protection systems. However, the instructions for implementation of the
