General This inspection was conducted to review the licensee's radiation protection program during normal operational conditions.
Reviewed was
,
organization and management controls, internal and external exposure controls, control of radioactive materials and contamination, and audits.
Also reviewed were corrective actions for past inspection findings.
Tours of licensee facilities were made to observe posting, labeling, and access and contamination controls; no significant problems were noted.
3.
Licensee Action on Previous Inspection Findings (IP 92701; 92702)
(Closed) Open Item (346/84-08-02):
Energy response of PASS noble gas channels.
The licensee purchased high range monitor enhancement kits from the vendor and installed the kits in the PASS noble gas monitors.
The installed enhancement kits greatly reduce the energy dependence characteristics of the monitors.
(Closed) Open Item (346/86009-01):
Complete the " supervisory review" of the Fuel Handling Ventilation System.
The review was completed; some long term recommended enhancement actions resulted.
No immediate corrective actions were found necessary.
(Closed) Open Item (346/86029-01):
Reporting of Sr-89 and Sr-90 LLDs, etc., in semiannual effluent reports.
The procedure for preparation of

.
. semiannual effluent reports has since been revised to include LLD values and "less than" symbols.
(Closed) Unresolved Item (346/88008-01):
Evaluate dose assignment
.
methodology to show compliance with Form NRC-5.
The licensee's evaluation showed that their current beta eye protection is sufficient to preclude eye dose except for exposure to maximum potential beta energies; the fraction of beta radiation exposure at maximum potential beta energies would result in dosimetry errors less than the normal errors in measurement of radiation dose.
The licensee's beta eye protection program appears adequate.
[ Closed) Open Item (346/88016-01):
Internal responses to the May 1988 quality assurance audit findings.
The inspector reviewed the licensee's internal responses to the audit findings; the actions taken appear adequate and appropriate.
(Closed) Open Item (346/89004-01):
Responsibilities for radioactive effluent monitoring systems need to be specified.
Responsibilities have been assigned, tracking systems developed, and internal reporting systems enhanced.
Implementation will be reviewed as part of future routine inspections.
(Closed) Violation (346/89004-02):
Unplanned release activity not included in semiannual report.
The inspector reviewed implementation of the corrective actions described in the licensee's letter of response dated March 27, 1989; the corrective actions are adequate.
No further problems were noted.
4.
Radiological Control (RP) Organization, Changes, Management Controls, Training, and Qua'lifications (IP 83750)
The inspector reviewed the licensee's organization, management controls-and qualifications for the radiation protection program including changes in the organizational structure and staffing, effectiveness of procedures and other management techniques used to implement these programs, and experience concerning self-identification and correction of program implementation weaknesses.
There have been no significant. programmatic or structural changes to the licensee's RP organization, management controls, and qualifications since described in previous radiation protection and radwaste management inspection reports.
The licensee began conducting advanced radworker training classes earlier this year; about 10 classes of 10-15 persons have been conducted for station personnel.
The five-day training includes mocked-up, hands-on radiological work situations.
The inspector observed a portion of the mock-up training and discussed the training course with licensee personnel.
The training appears good, is well received, and should result in improved compliance with good health physics practices by radiation workers.

~5; cExterna1 Exposure Control LIP 83750);
.The' inspector. reviewed the' licensee's external exposure control'and personal _ dosimetry programs, ' including:, changes in program to meet outage n6eds;<use of dosimetry to determin'e whether requirements are met; land required records.: reports.and' notifications.
The: licensee's external-exposure controls' program was extensively reviewed during.the team inspection conducted during February and March 1988, and'
Ldescribed in Inspection Report.No.. 50-346/88008(DRSS).
No significant-programmatic changes have.since been made.

PersonnelwhSlebodydosefor1988'wasabout304' person-rem.
As'of'
L June:30, 1989, t'e whole body dose for 1989 was about.18 person-rem.' The l
. goal for:1989 is 50 person rem. No extended outage:is planned during 1989.
No violations or: deviations were identified.

Internal Exposure Control (IP 83750)
The. inspector. reviewed 1the licensee's internal exposure control and u
'
- assessment programs, including:
changes to procedures affecting
~
.
Linternal exposure control and personal assessment; determination whether engineering controls. respiratory equipment, and assessmentLof individual-
.
'
intakes meet regulatory requirements; and required records,, reports,- and notifications.
i The' licensee purchased a stand-up whole body counter.and was calibrating it during this inspection. The licensee plans to use the. stand-up.
counter as > the primary counter,' and their chair-type counters as backup il and for overflow.
i The inspector reviewed whole body counting results for 1989 through
' June.
No intakes in excess of the'40 MPC-hour control measure were noted.
Based on whole body counting and tritium urinalysis results,
'there is no indication of weaknesses in the licensee's internal exposure control.and assessment program.
No violations or deviations were identified.
7.
Control of Radioactive Materials and Contamination (IP 83750)
-The' inspector reviewed the licensee's program for control of radioactive
- materials and contamination, including:
adequacy of supply, maintenance, and calibration of contap+.ation survey and' monitoring equipment; effectiveness of survey methods, practices, equipment and procedures; Ladequacy.of review and dissemination of survey data; and effectiveness of methods of control of radioactive and contaminated materials.
During tours of radiologically controlled areas, the inspector noted that housekeeping was good and that most of the previously observed leak catch containments have been eliminated by effectively repairing the leaking equipment / valves.
Also noted was that the new Low Level Radwaste Storage

. Forty-one personal contamination events were" recorded during 1989 through:
June;' eleven of'these ' events were recorded during June with ten being clothing contaminations.
Each event is investigated to determine' root.-
cause..When the root cause is determined to be lack of attention to-detail by an~ individual, the individual is counseled on good contamination
- control practices. The licensee's goal _is to experience less than four events'during non-outage months'and less than twelve during outage months.

.
The licensee has-installed and made operational:a whole body frisker ('
centrally located in the LLRSF, and one at the'LLRSF exit to the radiologically uncontrolled area.
Also located at this exit is equipment.
used to monitor materials prior to release from the RCA.
No! violations or deviations were identified.
. 8.
' Audits and Surveillance (IP 83750)
The inspe'etor selectively reviewed the results of ststion quality'
' assurance' audits and surveillance conducted between August 1988 and.
May 1989. One audit and six surveillance were reviewed.
The audit-concerned calibration of measuring and test equipment; the surveillance.
included reviews of several aspects of the radiological protection program.
Several! observations and findings resulted from the audit and
. surveillance.
The licensee's QA program includes adequate mechanisms to follow up on identified. findings.
The: frequency and extent of audits, and qualifications of auditors,
-appears good.
No' violttions or ' deviations were identified.
9.
Exit Meeting (IP 307031 The: inspector. met with licensee representatives (denoted in Section 1)
at the conclusion of the inspection on July 28, 1989, to discuss the scope of the inspection and the findings.
The inspectors also discussed the likely informational content of the inspection report with regard to documents or. process reviewed by the inspectors during the inspection.
The license identified no such documents / processes as proprietary.
The following matters were discussed specifically by the inspector:
a.
The improvements noted in storage of reusable contaminated equipment
'
and materials (Section 7).
b.
The advanced radnrker training program, and the desirability of continuing the program (Section 4).
