General This inspection was conducted to review various aspects of the licensee s i radiation protection program during a refueling and maintenance outage,
' including: the April 3,1989 hot particle event, changes since the last inspectiord audits'and surveillances, exposure. control, control of ! radioactive materials, ALARA,- and the licensee's corrective actions - regarding previous violations and identified concerns.
During the
performance of plant tours, no significant access control, posting or procedural adherence problems were identified. Housekeeping and material conditions were' generally good.
However, housekeeping was. poor in the-lower two levels of the primary auxiliary building and the lower level of both facade buildings.

Particle Collection 'On April 3,L1989,"while~ performing a survey of the reactor cavity,- y" . _ N La' health physics technologist (HPT). accompanied by a HPT trainee . -encountered a-hot _ particle located on the floor. -The HPT's - - teletector exhibited ^a reading of-2-3; rem /hr.- The HPT attempted , to collect this particle by utilizing a piece of tape, The tape
- was pressed onto the_ particle by the HPT'sileft: hand.-MThis.
technique.was employed several: times 'until-therparticle was- .,1 "
h captured.1 :The teletector was used tolprovide-confirmation,of-
particle col.lection between-attempts and upon collection. The tape with the adhered. particle was then placed inta plastic. bag which was<. 1-then set 1 adjacent to the: cavity wall., At thisLtime, the particle had.
- been3
' g; 1n contact with=the HPT's left h'and for-approximately six: . secondsL(as determined through'a're-enactment). ' " Tho'HPT-a^nd1HPT. trainee continued their survey of the. lower cavity > i_
' = collecting' approximately five hot _ particles of significantly-- lower activity, The-HPT who collected t.he: initial particle:then -
- measured:the bag containing that particle with a.n' ion chamber <
in strument < (Bicron' RS0-50). The observed dose rate was in excess; . of 50 rem /hr_with'the window open.
The HPT verified this dose rate y with-a'different ion chamber instrument'(BicronLRS0-50). The: $ .
- observed dose rate this' time was'also in excess of 50 rem /hr with
- '
Lthe-window _open.
Each time these; readings wereitaken, the-HPT who1 captured:the' hot particle handled:the bag containing the particle.at ' the open end of the bag. -Tho' plastic bag'containing the1 particle was then tied.to a rope which was suspended from the 66' elevation of the containment.
- ,mm The collection of low activity particles with tape is generally an. industry acceptable practice.
However, the collection of~high . , ' , activity particles by hand, held adhesive tape is not an acceptable . practice.
The inspectors reviewed the training records for the HPTs _ and the approved radiation control procedures for hot particle %", collection and handling methodology.
While nuclear ' industry . experiences with hot particles and skin dose assessment methodologies , l ,
y a - I ' < ,
' , ,
- ,.
- , were discussed in the training lesson plans, hot particle collection, ' handling and action level instructions topics were not presented.to the_HPTs. Approved radiation control procedures that provided instructions for hot particle collection, handling and action levels were not available to station personnel, b.
Management Notification and Review Upon exiting from the reactor cavity, the HPT notified a health physics supervisor of the collection of the hot particle. The HP supervisor called the Health Physicist at home and reported the hot particle. The Health Physicist asked that the applicable surveys be placed on his desk by morning.
On' April 4,1989, the Health Physicist forwarded the surveys to the Superintendent'- Health Physics and the Nuclear Specialist for review.
The Nuclear Specialist wrote a report to the Superintendent - Health Physics that identified dose rates greater than-200 R/hr beta-and 8 R/hr gamma on contact and 12 R/hr beta and 500 mr/hr gamma at eighteen inches. This report also discussed potential problems in performing an analysis using acid digestion, multichannel analysis and recommending a radwaste drum analysis methodology.
Included in this report was an initial dnse assessment of 2 rem skin dose from the reported surveys and handling methods, but no discussion was provided on the collection method.
On April 4, 1989, the Superintendent - Health Physics reviewed this report and returned it to the Nuclear Specialist with written comments, These comments requested a determination by the Nuclear Specialist of_the need for analysis; agreed that personal statements were needed; questioned the methodology of the initial dose assessment and directed him to ensure that the hot particle guidelines were implemented.
On-April 4, 1989, the Nuclear Specialist revised the report to the Superintendent - Health Physics.
This report maintained the previous exposure rate _information.
The Nuclear Specialist indicated that the need for analysis of the hot particle and determination of whether a significant beta skin exposure occurred would be based on the personal statements provided.
In addition, a worst case skin dose estimate would be less than two tem from surveys and reported handling methods. This estimate assumed a six-minute exposure at eighteen inches from the bag for a skin dose to the extremities.
In summary, health physics management was aware that a significant hot particle had been found. The need to obtain additional information regarding the potential exposure was recognized.
Concerns expressed by the Superintendent - Health Physics regarding the initial dose assessment methodology were not addressed.
Lastly, dose assessment information which did not have an adequate basis was communicated to the Superintendent - Health Physics.

Root Causes The inspectors reviewed the event, interviewed licensee personnel and evaluated' documentation. The following delineates the primary root causes of the hot particle incident of April 3, 1989.
' (1) HPTs did not receive adequate-training in the methods to minimize radiation exposure during the collection and handling of hot particles and activated components.
(2) Established methods and approved radiation control procedures for collection and handling of hot particles and activated components, including action levels to minimize radiation
exposure were not available to the HPTs.
(3) Approved procedures and methodologies to perform dose assessments were not utilized to evaluate potential radiation exposures.
(4) Poor communications among health physics management personnel contributed to the failure to recognize the significance of this event.
(5) Organizational responsibilities and duties (hot particle program) were not clearly delineated.
This contributed to the confusion and communication breakdowns, g.. Event I'nvestigation Committee Recommendations The Event-Investigation Committee made the following recommert tions to prevent recurrence of this event: ) . (1) Include in the Training Program for HP personnel proper methods for handling hot particles on both people and surfaces. This should include proper methods for detection, retrieval cnd storage.
Jq (2)- Formally assign lead responsibility and authority for the Hot j Particle Program.
(3) Limit offshif t calls to the -Health Physicist to things requiring immediate action. This includes training HP Su -; take necessary actions without contacting (the)pervisors to Health Physicist.
(4) Implement the following to improve two-way communications in , the Health Physics Group: ! W (a) Define responsibilities of the HP Supervisors during ! outages to assure HPTs are aware of specific supervisors' responsibilities such as: Personnel concerns, day-to-day
HP activities, specific projects follow up of concerns, etc.

This individual had received General Employee Training, a guided tour of the primary auxiliary building and.had been. instructed-in the access requirements for containment.
These three incidents are apparent violations of High Radiation Area entry -requirements specified by Procedures HP 2.5 and HP 2.5.1 and
are representative of violations that could reasonably be expected to , qv have baen. prevented by the licensee's corrective action for the previousviolations(No. 266/90003-03; 301/90008-03).
One apparent-violation with three examples was identified.
, '6.
OrganizationalandManagementControls(1 83750) The inspectors reviewed the licensee's organization and management l controls for the radiation-protection program, including: organizational structure, staffing, effectiveness of procedures and other management techniques used to implement the program and experience concerning self-identification and correction of program implementation weaknesses.
Early in 1990, a new Superintendent - Health-Physics was appointed.
A transition period of approximately three months was utilized to allow continuity between the two individuals. The replacement HP Superintendent has assumed full responsibilities. The transition process between the HP Superintendents apparently went smoothly.
The Nuclear Specialists' training and qualifications were reviewed.
Each of the nuclear specialists appears to be well qualified and to have a. suitable academic background. Current plans include the addition of 4-5 HPTs to the health physics staff to support radwaste activities.- 7.
External Exposure Control and Personal Dosimetry. (IP 83750) The inspectors reviewed the licensee's external exposure control and personal dosimetry programs, including: changes in facilities;-equipment, personnel, and procedures; adequacy of the dosimetry program to meet routine needs; required records, reports, and notifications; effectiveness of management techniques used to implement these programs; and experience concerning self-identification and correction of program implementation weaknesses.
No exposures greater than 10-CFR 20.101 limits were noted.
No individual ', exceeded the licensee's administrative quarterly whole body limit of 2500 mrem.
The licensee has been evaluating an electronic dosimetry system for use at the plant. Currently, they are evaluating methods to interface this system with the installed exposure records system.

m , k > , . ' . The licensee's actions after identification of-the audit finding were timely. Corrective actions have been completed which should prevent ' future occurrences. Consequently, pursuant to Sections V.G.I. of- .(Appendix C to 10 CFR Part 2), a Notice of Violation will not be ~ issued for this Severity Level IV violation (NCV No. 266/90008-04; 301/90008-04).
b.
Corrective Action Implementation > The corrective action designated for closure of AFR A-P-88-13-060' had not been. completed by the committed due date of April 14, 1989.
The-corrective actions identified included procedure and checklist revisions for radwaste shipping activities. The audit response indicated a-new commitment due date of April 1, 1990, for the procedure and checklist revisions.
As of April 26, 1990, the inspectors determined that the-procedure and checklist revisions have yet to be approved and implemented.
10 CFR 50 Appendix B, Criterion XVI requires that measures shall be established to assure that conditions adverse to quality such as failures, deficiencies, deviations and nonconformances are promptly identified and corrected.
This is another example of a violation.for which an enforcement action.has already been proposed (References: EA 89-254, Dated April 17, 1990, Inspection Reports No. 50-266/89033; No. 50-301/89033(DRP) and No. 50-266/89032;No.50-301/89032(DRP)). No surveillances had been performed since the last inspection.
One violation was identified; however, a notice of violation of ' will.not be issued.
10. Maintaining Occupational Exposures ALARA (1 83750) ' The inspector reviewed the licensee's program for maintaining occupational exposures ALARA, including: ALARA group staffing and qualification; changes in ALARA policy and procedures, and their implementation; ALARA considerations for planned, maintenance and refueling outages; worker awareness and-involvement in the ALARA program; establishment of goals and objectives, and effec'tiveness in meeting them. Also reviewed management techniques, program experience and correction of self identified program weaknesses.
The total station dose for 1990 was approximately 91 person-rem of which about'75 person-rem was attributed to the ongoing Unit I refueling and maintenance outage. The licensee's 1989 total dose of 474 person - rem indicates no significant change from previous years. This undergoes two refueling and maintenance outages each year (plant normally 12 month fuel cycles). Total exposure for the previous six years is listed as follows:
- we m
. Year Person-Rom R<. arks i 1984 737.155 Includes 245.650 rem for Unit 1 SGRP 1985 444.050 1986 375.480 1987 532.010 1988 387.255 1989 474.390 No violations or deviations were identified.
11.
Exit Interview (IP 30703) The inspectors met with license representatives (denoted in Section 1) following the inspection on April 26, 1990, to discuss the scope and . findings of the inspection, including the apparent violations (Sections 4 ' and 5).
The inspectors also discussed the likely informational content of the inspection report with regard to documents or processes reviewed by the inspectors during the inspection.
Licensee representatives did not identify any such documents or processes as proprietary, i e . 16 }}
