2.0 Purpose

The purpose of this routine, unannounced inspection was to review radiation

protection activities associated with the Saxton Nuclear Experimental

Corporation (SNEC) reactu site.

The following areas were included in this

review:

- status of previously identified items,

- status of decontamination efforts,

- status of ongoing rclease survey effort,

review of SNEC records maintained at the TMI E0F in Harrisburg, PA,

- revicw of radiological status of the Saxton site soil.

.During the course of this inspection the NRR Project Manager visited the

site on April 28, 1988 for familiarization purposes.

follow-up reports fo(r three Containment Vessel sump water samples in

3.1

excess of 10 CFR 20 activity concentrations in accordance with

Technical Specification requirements.

In response to the above violation the licensee initiated the use of

already existing GPUN procedures governing regulatory correspondence

at Saxton to insure required reports are made.

The inspector reviewed

Containment Sump sample results and corresponding 15 day reports for

sump samples collected during the last quarter of 1986, all of 1937,

'me from sample collection to report generation was typically

.approximately 30 days rather than the 15 day notification as required

bytheTechnicalSpecIfications.

This apparent untimeliness was also

noted and reported by the licensee's Operations QA group.

The inspector discussed the above timeliness concern with the

licensee. The licensee indicated that, due to the site's rcmote

location and need to ship samples back to TMI for analysis,

significant delays could occur between sample collection and analysis.

The licensee indicated they felt the "15 day clock" started when they

received the sample analysis results from the lab.

This was often 2-3

(Closed

Inspector Follow-up Item (146/86-02-02): Review Saxton

Radiolo ical Environmental Monitoring Program (REMP) annual reports

for 198 , 1983, and 1984.

NRC Inspection Report No. 50-146/79-01 identified specific areas

outside the Saxton site fence but within the PENELEC fence where soil

radioactivity concentrations ()rimarily Cs-137) were above background.

Review of the above licensee REMP reports also indicated above

background levels of Cs-137 activity are present in the soil within

the Saxton fence. The status of the Sexton soil and licensee plans

for additional evaluation are discussed in section 7.0.

This item is

closed.

As of the date of the inspection, REMP reports for 1985 and 1986 were

not available.

The licensee indicated that although samples had been

collected and analyzed for these periods, results had not received

final review and the final reports had not been issued.

The licensee

indicated an individual has been detailed to complete these reports

and stated during the conference call on May 16, 1988 that a

comprehensive REMP report would be available by May 31, 1988.

This

report will be reviewed during a subsequent inspection.

4.0 Status of Decontamination Activities

From approximately July, 1987 to February, 1988, decontamination work was

p(erformed by the licensee in the Radioactive Waste Disposal Facilitythe Control

reduce), surface contamination levels to Regulatory Guide 1.86 limits.

RWDF

Easily removable items (partitions, vent ducting, etc.) were surveyed by

Health Physics (HP) technicians and released when appropriate. Material

above the release limits (including scabbled concrete and the sectioned

Refueling Water Storage Tank) was shipped offsite as radioactive waste for

burial or for additional decontamination / volume reduction.

The inspector reviewed radiological controis associated with the above

activities by the following methods:

- review of applicable SNEC procedures,

- review of the SNEC HP logbook,

- discussion with cognizant personnel,

- review of selected Operations QA monitoring reports,

- review of selected surveys,

- tour of the SNEC site.

Within the scope of the above review, one apparent violation, concerning a

failuvo to document a release survey, was identified and is discussed

below.

4.1 Failure to Document , Survey.

During a tour of the site the inspector noted that decontamination

activities in certain areas had been extensive; for example, certain areas

,

of floor had been excavated in the CAB and RWDF.

During the tour the

inspector noted a residual cut section of a large (approx. diameter 22")

pipe jutting out of the pipe tunnel.

The licensee indicated the pipe,

which was originally approximatelv 20 feet long and ran below-orade from

the RWDF to the pipe tunnel, had been exposed and surveyed in August, 1987.

Approximately half of the pipe was released as clean material at that time.

The 1:censee indicated the remaining section of pipo (excluding the

resiQ al portion) was surveyed and released in March, 1988.

The inspector reviewea the survey perfor.ned in August,1987 and noted the

portion of pipe released at that time was clearly shown to meet SNEC

release criteria (i.e., less than 100 net cpm).

This survey showed the

remairing section of pipe included measurable activity above release limits

(200 net cpm).

The licensee stated that when this remaining section of

pipe was released in March,1988, a suryny was performed and all sections

of pipe above r' lease limits were cut out of the pipe and disposed of

separately as radioactive waste. The licensee stated, however, that the

survey performed in March, 1988 was not documented.

10 CFR 20.201(b) requires the licensee to perform surveys as necessary to

demonstrate compliance with the regulations and as are reasonable to

evaluate radiation hazards.

10 CFR 20.401 requires the licensee to

maintain records showing the results of surveys performed to comply with 10

Based on collaborating evidence by several individuals

CFR 20.201(b)he pipe survey and disposal occurring in March,1988, the

.

involved in t

inspector concluded that the licensee did in fact survey the pipe prior to

disposal but failed to document this survey.

Failure to document the

survey of the pipe demonstrating it met release criteria prior to its

disposal constitutes an apparent violation of 10 CFR 20.401 (146/83-01-01).

The licensee stated that it was felt the above deficiency in survey

documentation was an isolated instance and not a generic concern.

The

licensee also stated, however, that a review would be performed to insure

additional lapses in survey documentation had not occurred for material

that had been released.

The licensee also indicated that efforts would be

trada to retrieve the subject portion of pipe from the landfill to verify it

had been adequately surveyed.

Licensee efforts in this area will be

reviewed in conjunction with the licensee's response to the violation,

4.2 Audits of_ Radiation Protection Activities

l

Both the TMI Radiological Assessor and the Operations QA group provided

independent assessments of activities at Saxton during the decontamination

!

work. The inspector reviewed selected QA reports and noted that they

l

identified repeated HP deficiencies, including the following:

- individual failing to frisk upon exit from a contaminated area,

l

- individuals wearing clean protective clothing outside the site fence,

- repeated failure to appropriately label and seal drums containing

i

scabbled concrete,

l

- Inappropriate control of a drun containing scabbled concrete.

,

!

Due to the low levels of contamination involved, the above instances do not

represent violations of NRC posting and labeling requirements. They are

indicative,however,ofalackofappropriatemanagementoversightand

,

control of the decontamination work. The licensee s organization to

l

support the work .nay have contributed to this lack of eversight: tath the

'

i

decontamination workers and the HP technicians responsible for maintaining

radiological controls were supplied by the same vendor.

Consequently,

'

there was not an effective organizational separation and independence of HP

and production personnel,

The licensee indicated that upper management became aware of radiological

control concerns at Saxton and that personnel changes and upgrades were

made to' improve oversight. These included appointment of a new Radiation

Safety Officer and establishment of a GPUN qualified HP technician at the

site as lead technician.

The inspector noted these improvements were of

limited effectiveness; several deficient conditions reflecting a lack of

management attention were still observeable during the inspection and are

discussed in section 5.0.

The overall level of QA and Radiological Assessor involvement at Saxton was

noted to be a licensee strength and appeared to be effective in identifying

significant concerns.

5.0 Status of Release Survey Effort

The licensee started performing surveys to demonstrate the CAB, RWDF, and

the pipe tunnel are within the contamination limits of RG 1.86 (i.e.,

tsuilding release surveys) on February 1, 1988.

Surveys were still being

performed durin

The licensee is using

NUREG/CR-2082, g the time period of this inspection. Monitoring for Compliance Wi

Survey Criteria," as guidance for the performance of these surveys.

Completed surveys are reviewed by a qualified HP technician and then by the

Saxton RS0 or his designee to insure compliance with licensee procedure

9400-ADM-4500.12, "Radiological Surveys: Requirements & Documentation."

The insoector reviewed the licensee's performance in this area by the

following methods:

- discussion with cognizant personnel, including individuals performing

release surveys,

- review of selected release surveys

- review of selected Operations QR mo,nitoring reports,

- review of selected l'icensee procedures.

Within the scope of the above review, several significant deficiencies were

noted which collectively question the adequacy of the release surveys

parformed up to the date of the inspection.

The following specific

deficiencies were noted by the inspector:

o No specific procedure was in place to control the performance of the

building release surveys.

The inspector noted the licensee had approved

,

both a radiation and contamination survey procedure; however these were

noted to be general in nature and did not address specifics being performed

during the building release surreys.

The licensee stated that a draft "final survey" procedure ~had been produced

but that significant changes in survey methodology kept occurring which

created difficulties in keeping the draft up to date.

o Training for individuals performing building release surveys was informal

and incomplete. The inspector noted the licensee was using a practical

factor sign-off form, which indicated that individuals had demonstrated

proficiency in instrument use, as documentation that surveyors were

qualified to perform their activities. The inspector noted, however, that

no procedure was in place recognizing this sign-off form and that no lesson

plan or procedure was available to indicate how reviewers judged the

individual's proficiency before signing the form.

The inspector also noted

numerous surveys had been completed by individuals using instruments they

had not been signed-off on.

o Formal procedures did not exist for calibration of several of the

instruments used during the performance of the release surveys.

no approved calibration procedure exists for the PRM-6 and

Specifically,dditionally, although a calibration procedure is currently in

the ASP-1. A

place for the PRS-1 and PRS-2, these instruments were used prior to the

development of a calibration procedure.

For the above instruments,

calibrations were performed using the vendor manual as a guide.

This

concern was originally identified by the licensee's QA group,

o Completed building release surveys were of poor quality and did not meet

the requirements or standards of the licensee's survey documentation

procedure (9400-ADM-4500.12).

In addition to poor overall legibility, the

following deficiencies were noted:

- non-standard forrrs were used; consequently, required information

concerning instrument type, calibration date, etc., was not present

on each page of each su~rvey,

- survey information was given in pencil, rather than the industry

standard of indelible black ink,

- correction fluid was used to make corrections on some of the

surveys, rather than a single line-out with initials,

- extraneous comments not relevant to the survey had been included on

some of the survey sheets.

The inspector noted the above deficiencies existed on surveys that had

already passed initial and in some cases secondary review by the licensee.

In light of the above weaknesses in 3rocedures, training, instrument

calibration, and overall survey legi aility and level of review the

inspector concluded that the adequacy of the building release surveys

performed up to the present date was extremely questionable.

The inspector

'

.

.

.

noted that the potential existed for several apparent violations of

Technical Specifications section 4.d which requires in part that radiation

surveysbeperformedinaccordancewithwrittenprocedures.

The inspector

"unofficial,however, that the status of the above release surveys was still" in that n

recognized

and the licensee had not formally submitted them to the NRC for review.

The licensee stated that the above deficiencies with the building release

surveys had already been recognized by licensee management.

During the

week of this inspection the Radiological Assessor and Saxton RSO held a

previously scheduled meeting to review the release surveys and assess their

adequacy and whether or not they could be used. During the exit meeting

senior licensee management stated that the following actions would be

completed:

- overall review of surveys would be completed,

- procedures for instrument calibration, c.Jalification of surveyors,

and for performance of the release sur"ey would be developed and

approved,

- all questionable surveys would be redine.

The status of the licensee's final building release surveys will remain

unresolved pending review of the above improvements (146/88-01-02).

The inspector stated during the exit meeting that licensee performance

during the decontamination and surveying activities was not commensurate

l

with that seen at other GPU facilities and reflected a lack of effective

planning and management involvement. The licensee noted this concern and

stated that effective control may have been hampered, in part, by the

remoteness of the location and the heavy reliance on an extremely transient

contractor workforce.

The licensee indicated that several steps had

already been taken to improve the level of management control upon initial

,

identification of performance deficiencies at Saxton (see section 4.0).

I

6.0 SNEC Record Review

,

On April 27, 1988, the inspector reviewed SNEC files maintained at the TMI

l

E0F in Harrisburg, PA. No deficiencies were noted.

The inspector was

!

unable to find, and consequently requested from the licensee the following

documents:

- copies of original site construction plans showing the location of pipes,

tanks, etc. in the site yard,

l

.

.

.

.

,

- copy of the original site release survey performed in 1973.

The licensee indicated they would search their records and provide the

requested information if available.

7.0 Radiological Status of the Saxton Soil

A telephone conference call was held between the individuals denoted in

section 1.0 on May 16, 1988 to discuss radiological status of the soil in

and around the Saxton site fence.

During that call, the licensee indicated

the following:

- Contamination within the Saxton site fence appeared to be restricted to a

dark, flyash-like soil . The licensee indicated maximum activity levels

in this flyash-like soil ranged from 50-60 pCi/g.

The licensee

indicated typical background levels ranged from 2-4 pCi/g.

The inspector

noted that the licensee's 1982 REMP report showed an 870 pCi/g sample

taken within the "ro ed-off" area within the Saxton fence.

The licensee

was a more represent tive,ple result but indicated the 50-60 pCi/g range

acknowledged this hi h sam

repeatable value.

- Soil activity was primarily due to Cs-137 which appeared to be tightly

bound to the flyash-like soil.

- Surveys performed by the licensee outside the Saxton fence but within the

PENELEC fenca in 1986 identified several areas of localized soil activity

above background.

The maximum level identified was 2200 pCi/g Cs-137.

The licensee stated that soil in these localized areas was dug up and

disposed of as radioactive material.

The licensee also indicated during the call that they were currently

negotiating contracts to have additional characterization studies performed

on the Saxton site and immediate environs.

Planned studies include an

extensive aerial or ground radiation survey, a geophysical analysis of the

flyash-like soil and sub-soil at the site, and additional radiological

analyses of the soil.

Results of these studies will be reviewed during a

subsequent inspection.

l

8.0 Exit Meeting

The inspector met with licensee representatives, denoted in Section 1.0 of

the report, on May 3, 1988. The inspector summarized the purpose of, scope

l

and findings of the inspection at that time.
