2.0 brpose The inspection was a routine, unannounced Radiological Controls Inspection of the following areas: Status of Previously Identified items, Audits and Appraisals, and Internal and External Exposure Controls.
3.0 Status of Previously ' Identified items b(Closed) Unresolved Item (50-374/89-21-03)L licensee to determine 3.1 record the highest dose to the dole body. On September 28, positioned to ody dose to an individual wearing dosimetry which was not 1989 an individual performing Foreign OWt Search and Retrieval work on the secondary side of the Unit 1 D n eam generator exceeded his administrative extremity dose 1 Mit. Upon review of the working conditions, it was determined that the individual's whole body dosimetry, which was positioned above the elbow, may have moved further up the individual's arm and not positioned to monitor the area of the whole body receiving the highest dose. The circumstances surrounding the exposure were reviewed in detail during Inspection 50-334/89 21.
The inspector reviewed the licensee's dose assessment for the individual involved as discussed in Incident Report No. 1-89-97 dated November 8, 1989. The licensee determined the individual's quarterly whole body exposure to be 2.076 rem. The inspector reviewed the adequacy of the dose assessment and concluded that the dose assessment methodology was adequate and no regulatory limit was exceeded. This item is closed.

l 4.0 Audits and Appraisals
The inspector reviewed several audits of the Radiation Protection (RP)it Pro ran which had been conducted b Aud$ts and Surveillances Departmenf.the licensee's Quality Services UnThelicenseej contractor to provide additional technical expertise in conducting the j
"Ra11ological Control-Calibration and Documentation" audit, conducted J
,
l Dece?ber 1989 through February 1990. The use of an independent contractor to assist in the uality assurance audits was partially in response to NRC I
conceri's regardin the lack of independent assessaents of the RP Program, i
The inspetor not d that the findings of the audits indicated that an
'
corrective actions had been taken to address audit findings.propriate
adequate assessment of the RP Program had been conducted. Ap
The licensee !rovided the inspector with a copy of a p$osal bid to have f
an independen contractor provide technical expertise the next scheduled audit. The licensee also stated that they are planning on conductina an audit during the third quarter of 1990 to address two
,
concerns Identified in NRY Combined Inspection Report No. 50-334/89 21; i
l 50-412 vendor /89-20. The concerns regarded the lack of audits to ensure thats who state their em)loyees actually have the required records and physicals and to j
ensure tie adequacy of the physicals. The licensee has been responsive to the NRC concerns in this area.
]
The inspector reviewed the internal surveillances conducted of the RP
)
Program. The different types of internal surveillances of the RP Program i
are detailed in Appendix I of the Radeon Manual and include Radiation Deficiency Reports, Supervisory, Technical and Administrative Surveillances. The number of these surveillances and the associated findings indicated that supervisors were routinely reviewing ongoing work activities.
)
,-
In general the licensee had been responsive to surveillance findings however the inspector did note an apparent need for long term correcfive i
actions for re) eat findings of weaknesses in the area of respirator maintenance. T1ese weaknesses are discussed in Section 5.0 of this report, l
5.0 Internal and External ExpoAure Controls The inspector conducted several tours of the facility and verified that
areas were properly posted, barricaded or locked as required. The inspector-1 also noted that the housekeeping throughout the facility was good.
The inspector toured the respirator maintenance and storage area. By j
,
!-
reviewing training records, licensee procedures, and respirator issue logs
the inspector determined that the licensee has an adeguate program to
<
l ensure that only individuals who have current physicals and fit tests are issued respirators. The inspector did note a weakness in the area of retraining the individuals assigned the task of respirator maintenance.

Currently the responsibility for various aspects of the respirator maintenance program is divided between four groups. Building maintenance is disinfecting, storino and issuing air purifying responsible for washing,l Controls is responsdie for inspecting and respirators. Radiologica performing maintenance on air purifying respirators. Operations is responsible for inspecting and performing maintenance on SCBAs. Maintenance is responsible for inspecting and performing maintenance on supplied air respirators.
The inspector reviewed the training records of several of the individuals who perform maintenance on respirators and noted that the individuals did not receive periodic retraining on maintaining the respirators. The licensee stated that individuals involved with respirator maintenance are only given initial training and that under their current program they do not receive periodic retraining. An individual could be assigned the task of performing maintenance on respirator.y protection equipment even if the individual had not been retrained or otherwise involved in respirator maintenance for several years. The lack of a retraining program for these individuals is an area that needs improvement.
The inspector reviewed the 1989 Respirator Protection Program Evaluation which included the results of severai surveillances of the respirator maintenance program. These surveillances identified several weaknesses which included: improper fittings on the air line regulators in the Control-Room, SCBA facepieces missing parts, and the lack of proficiency in caergency respirator inspection and repair by the res>onsible foremen. The inspector also noted that some of these deficiencies ind been noted during surveillances in 1988. Although the licensee immediately corrected the noted weaknesses, the licensee does not appear to have addressed long term corrective actions to address the root cause of-the weaknesses. The protection workers was also a concern identified. program for respiratory inspector noted that weaknesses in the retraining The need to address the root causes of the identified weaknesses was oftheNRCRegion1officeandMr.phoneconversationbetweenMr.R.Nimitz discussed in a July 10 1990, tele S. 1.acy, General Manager, Nuclear Operations Services.
The long term corrective actions to address the root causes of the weaknesses identified in the respiratory protection program is an unrasolveditem(50-334/90-16-01).
The inspector reviewed records of the quality assurance checks of the counting room instruments and the whole body counters. The inspector also reviewed calibration records for selected counting room instruments and portable radiation survey noters. No deficiencies were noted.
The inspector reviewed the licensee's program for issuance and control of portable radiation survey meters. The licensee has implemented an adequate program to ensure that only individuals who are trained and qualified to use portable radiation survey meters are issued the instruments.

i The inspector did identify an area for improvement regarding the periodic i
performance testing of portable radiation survey meters. Currently the i
licensee conducts a daily response check to ensure the operability of survey meters. During the daily response check, due to the low activity of the check source used, the licensee cannot ensure the operability of the
'
scales of survey meters normally used for surveying High Radiation Areas.
The operability of these scales is only verified during the instrument calibration, which is conducted every six months.
'
ractice was not in accordance with American Theinsectornotedthatthis-!ndardN3231978'RadiationProtection Nationa Standard Institute st i
Instrumentation Test and Calibration". This standard recommends, in Section
'
4.6 that to assure proper operation of the instrument between calibrations,theinstrumentbetestedwithachecksourceduring operation or prior to use. Reference readings should be obtained for one point on each scale or decade normally used.
e The licensee stated that they were aware of the limitations of the check source currently used and have been evaluating purchasing new check source devices which would address this matter. The licensee stated that prior to
thenextrefuelingoutage,scheduledforSeptember1990,theywouldeither l-I have the new check source devices in place or they would utilize the l
calibration source when conducting the daily response checks of survey meters. This item will be reviewed during a future inspection.
'
The inspector noted that the licensee is planning on making several improvements in their Radiological Controls Program. Planned improvements include:
Rewriting the RWP procedure in order to streamline the paperwork
-
requirements.
l Computerizing the generation of RWPs.
!
-
Developing custom work packages for radiologically significant repeat
-
evolutions.
'
('
Purchasing additional monitoring and training equipment such as
-
personnel contamination monitors, alarming dosimaters, and a steam generator mock-up.
,
'
Developing an ALARA incentive program.
-
The licensee is also evaluating conducting a full system decontamination in order to reduce the source term and therefore personnel exposures at the facility.
6.0 Exit Meeting
