(Closed) Open Items (254/87026-01; 265/87026-01): Needed improvements in laundry and laundry monitoring capabilities.

The licensee has since purchased and made operational a more efficient laundry monitor, and improved laundering techniques.

(Closed) Open Items (254/88013-01; 265/88013-01):. Review Generic Letter 82-12 conformance.

This matter is being addressed between the Region III and CECO corporate offices for all CECO nuclear stations.

(Closed)OpenItems(254/88013-02;265/88013-02):

Contract RPT t' raining.

The licensee has since developed a contract RPT training and testing program; the program was implemented before the start of the current outage. The program includes:

review of selected resumes; a brief

-

orientation; a theory test with required passing grades; and self study and testing of selected station procedures, policies, survey forms,'etc.

_(Closed)OpenItems(254/f9015-01;265/89015-01): Consequences of using

External Exposure Control and Personal Dosimetry (IP 83750)

'

The inspector reviewed the licensee's' external exposure control and q

personal dosimetry programsc including. changes-in the program to meet.

'

routine and outage needs; use' of-dosimetry; planning and preparation.for

'

maintenance and refueling tasks including ALARA' considerations; and.

t required records, reports, asid notifications.

,

The licensee's external exposure measurement and control program remains-

!

essentially as described in. Inspection Reports No. 50-254/89006(DRSS)*

'

50-265/89006(DRSS).

.

l

.

For?1989,- the station's total dose was about.900 person-rem; the= goal was 845 person-rem.: The goal _for'1990 is.1100 person-rem; as of March 22, the i

'

dose received during 1990-was about. 500 person-rem. -

The inspecters selectively reviewed-radiation work permits -issued during

1990. -No-significant_ problems.were identified.

Iiternal Exposure Controls and Assessment (IP-83750)

'

The inspector reviewed selected aspects-of the ensee's internal-exposure control and assessment programs incit:

determination whether

+

engineering controls, respiratory _ equipment, ad u:,sessment of intakes -

..,

(

meet regulatory requirements; and planning land. preparation.for maintenance:

'

and refueling-tasks including ALARA considerations.-

a The_ licensee's program for controlling' internal, exposures-include'the use.

?

-

,

of protective clothing, respirators and; equipment, and control of. surface y

and airborne' radioactivity. ' A selected review ofu RWPs, air activity.

surveys,- and.MPC-hour determinations for.1990 to date was made; no significant. problems were noted.7 RWPs -appeared to adequately, reflect the

respiratory protection requirements for the ' job.

The inspectors reviewed the licensee's Quality Control (QC)j checks'

~'

performed on= the: Fastscan Whole Body! Counter (WBC)' duringLeach shift in -

.which whole body counts are performed..'The inspectors noted that plots of these results are difficult to interpret and provide little useful

'*

information in their present~ form-because of the. selection of:x.and y-axis.-

size fAlso, the instrument history (maintenance performed, out-of-service instances,-remedial actions, etc.)_is~not documented. The inspectors discussed the information that may:be' derived from_ a good QC program and

>

-the elements of such a ' program. The licensee acknowledged the inspectors'

comments and agreed to examine this program and make appropriate' changes.

- Whole _ body count data wasiselectively reviewed for counts performed during-the period November 1989-through slanuary,1990 on. company and contractor personnel.

Followup counts, performed on persons who~showed elevated; initial counts, were adequate to verify that the 40 MPC-hour control'

measure was not exceeded.

No problems were noted.

No violations.or deviations were identified.

Control'of Radioactive Materials and Contamination (IP 83750)

The inspector reviewed the licensee's program for ' control: of radioactive t materials and contamination, including:1 changes in instrumentation, equipment, and procedures; effectiveness-of-survey methods, practices,'and-

.

. procedures; effectiveness of methods of control of1 radioactive and contaminated materials; management. techniques used to. implement the; program; and experience'concerning self-identification and correction of program implementation weaknesses.

,

lL

~ he licensee has. continued Lto improve appearance, housekeeping,f and -

T cleanliness in the turbine and auxiliary buil_ dings. During-the; current-outage,-the_ licensee is sending soiled _ cloth anti-contamination clothing to a licensed laundry for laundering.

The-licensee is-monitoring about)

ten percentLof: the returning clothing _-'as-a. quality assurance check of-laundering efficiency. The' monitor:is set'to alarm at 33 nanocuries.

No contaminated flaundry has been identified.

During-the current outage, the controlled area exit atithe Unit 2 trackway 1 is open and11s observed by stationmen who' have been upgraded (for the outage)'and trained to handle / issue respiratoryi protective devices, survey tools and equipment, and. monitor contaminationtpersons, y

No violations or deviations were identified.

}3 7.

-Personal Contamination / Hot Particle Incidents (IP 83750)-

1 The inspectors reviewed personal-contamination event (PCE): tracking and.

trending data for recent years. There were 531 PCEs reported in 1987,L472 j

in 1988, and 326 in 1989. The licensee established a goal of 325 PCEs for

'

1990. As of March 25, 1990, there_have.been 135;PCEsweportediwhich is greater tnan expe'ted. The licensee'sfinvestigation of= individual events c

has not identified reasons for the unexpectedly ~ high number of events.

The licensee stated that efforts'to reduce the= number of PCEs and investigate PCE events will continue to receive proper management j

,

attention.

n No skin doses greater than a small fraction-of applicable limits have been caused by hot particles during 1990 to date.

No violations or deviations were identified.

8.

Maintaining Occupational Exposures ALARA (IP 83750)

The inspectors reviewed the licensee's program for maintaining f

occupational exposures ALARA including. changes in-ALARA policy and j

procedures.

The ALARA group. structure remains essentially,as described in Inspection

'1 Reports No. 50-254/89006(DRSS); 50-265/89006(DRSS).

However, two

positions are unfilled. One graduate health physicist terminated j

employment early in 1989 and another recently : started SR0' training. The j

licensee is actively seeking replacements. Some ALAP,A' work was

_

q'

temporarily relegated to RP foremen and technicians to supplement the

No violations or deviations were identified, 9.

Audits and Assessments (IP 83750)

The inspectors reviewed records of onsite and offsite quality assurance audits and assessments conducted by the licensee during the period

July 1989 through February 1990.

Extent of audits and adequacy and timeliness of corrective actions were reviewed.

Two station audits were; conducted during the period; reviewed were various radiation protection and related subjects.

Identifie,d during these audits

.were incidents of failure to' follow radiation )rotection procedures and incidents of procedure content shortcomings; tie causes of the incidents and procedural shortcomings have since been corrected or are in progress..

-For those incidents corrected, the corrective actions appear adequate.

A performance assessment of radiation protection orgrnization and administration was conducted during August-September 1989 under the

+

sponsorship of the corporate health physics group. Several improvement i

items were identified and are being considered by the licensee. Post of-

'

the items are directed at procedures or practices that could be-changed to

make a situation / program more conservative or more broadly applied.

No.

l violhtions or regulatory requirements were identified by the auditors.
