Company HP staffing included 60 Radiation Protection (RP) positions allocatri' to the onsite RP program. Licensee epresentatives stated

%t all RP staff were qualified in accordance with ANSI 1 criteri No significant changes were expected in the technician staffin In addition, twenty-nine supervisory positions allocated to the RP group were staffed. The current radiation protection staff md supervisory personnel appeared adequate to provide coverage for roet.ine non-outage activities. No concerns regarding the FP&L TPN permacent HP staffing levels were identifie _

.

H No violatioris o.r deviations were identified, Contractor HP Techniciant Licensee representatives stated that in 'how.r.Sii UM, ippreri.Titi:ij 220 contractor HP technicians were hired for the dual unit outag The original contractor staff consisted of 34 deconers, 28 control point technicians, 3 supervisors, 10 senior administrative technicians,110 senior technicians, and 40 junior technicians. As of February 10, 1991, the contractor staff was reduced to approximately 2 supervisors, 84 senior technicians, ' 34 junior technicians, 8 administrative technicians, 8 deconers, and 20 control point personne The inspectors noted and discussed with cognizant licensee representatives the significant reduction in the current versus initial number of deconers utilized for the outage. Licensee representatives stated that subsequent to cavity decon activities, the majority of contractor decon personnel were released. Subsequent decon activities were conducted utilizing contract laborers properly l trained and supervised by HP technician Licensee representatives shted that during the current outage direct supervisory review of fiem 'tivities was doubled relative to l

previous outages. The change was initiated to improve coordination l and control of HP activities and coverage for the extensive outage

'

activities. In addition, to improve coordination and review of ongoing initial outage activities, two lead technicians were assigned to both the Refueling Floor and Biowall access control points. The

~ General Employee Training (GET)

Licensee administrative procedure 0-ADM-306, General Employee Plant l Access Training, dated December 19, 1989, nscribes the training (

program for employees who require unescorted access to TPN plant i site. GET is divided into two categories. Category I is provided to

'

employees requiring unescorted access to the protected area while Category II, Radiation Controlled Area Training (RCAT), is provided to employees requiring unescorted access to the Radiation Controlled Area (RCA). Both categories require 4 ainees to pass an exam with a i minimum of 80 percent correct. RCAT also requires trainees to pass performance tests. Employees qualified in GET during a given month remain qualified through the last day of that same month of the following year, at which time retraining is require From review of training procedures and course outlines, and discussions with training personnel, the inspectors noted that the program met the provisions of 10 CFR 19.12. Exams reviewed C

from both categories of GET were appropriate to verify an lvidual's understanding o' the material presente RCAT trainee's performance tests involved demonstrating proficiency in a full dress mock-up of entering and exiting contaminated areas. The mock-ups appeared adequate as wel The inspectors reviewed selected GET records for workers signed on RWPs associated with RTO removal and trash sorting activities.

l 1 HP Technician Training l

Licensee administrative procedure 0-ADM-360 Health Physics

! Department Personnel Training and Qualifications, dated August 5, i 1990, provides for the initial and continuous training programs for J HP technicians and also for their pending qualification. The l

procedure outlines the four levels of the RP training program. The

first three training levels are provided to indoctrinate technicians

! in scientific and HP fundamentals and skills training. A trained and l

qualified RP is expected to assume the routine shift duties required

'

by the HP Department. Level IV training is designed to provide

'

continuing training for RP staff and Junior RP (JRP) staff on plant j and industry changes and lessons learned, identified knowledge and j performance weaknesses, and emergency duties.

f Following discussions with cognizant licensee employees, the inspectors noted that RP staff and JRP staff are provided with two j weeks per year of continuing training which includes systems training to accent the radiological concerns associated with particular reactor systems. This training included classroom instruction and discussion, and when applicable, involved the use of mock-ups. The inspectors were informed that all licensee RP individuals were given .

TIP training during the last training cycle of 199 Review of selected exams from TIP training verified that training adequately

_

'

reviewed reactor functional, as well as radiological concerns associated with TIPS. Exams of all RP staff reviewed were passed l with a minimum of 80 percent correct. The inspectors also toured the licensee's mock-up training facility. Available mock-ups included l

- TIPS, reactor coolant pumps, and various other pump and valve mock-ups. During discussions with cognizant licensee employees, the j inspectors noted that extensive use of mock-ups was a training

!

program strength.

.

! Procedure number 0-ADM-360 also specifies training and qualifications j for contract HP technicians. In accordance with ANSI /ANS-3.1-1978

'

criteria, the procedure requires ANSI contract technicians to have a minimum of three years of working experience in their specialty of which one year should be related technical training. The inspectors reviewed selected ANSI contract technician's resumes and verified compliance with ANSI 3.1 requirement Procedure number 0-ADM-360, requires unsupervised non-ANSI contract HP technicians to be qualified to perform detailed job function Qualification of a technician to perform selected tasks is demonstrated by satisfactory completion of the applicable Job Performance Measure (JPM). The inspector reviewed records for selected non-ANSI contractors technicians and verified satisfactory completion of JPM No violations or deviations were identifie ~ - . ._ . . -. - _ _. 3,

4. Respiratory Protection Program (83750)

10 CFR 20.103(c) permits the licensee to maintain and to imr: ment a respiratory protective program that includes, at a minimum: air sampling l to . identify the hazards; surveys and . bioassays to evaluate the actual exposures; written procedures to select, fit and maintain respirators;  ;

written procedures regarding supervision and training of personnel and l issuance of records; and determination by a physician prior to use of l respirators that the individual user is physically able to use respiratory 1 protective equipmen l Health physics administrative procedure 0-HPA-060, Respiratory Protection Plan, dated August 5,1990, provides guidelines and general information for maintaining, issuing, and using respiratory protective equipment to limit inhalation of airborne radioactive material. A successful medical )

exam and completion of respiratory protection training are recuired prior '

to respirator use and annually thereafter. A quantitative fqt test is required prior to use and biennially thereafter. The inspectors noted i that training and medical qualifications met 10 CFR 20.103(c)  !

requirement The inspectors reviewed current respiratory protection program records to verify training, completion of medical physicals, and fit testing for selected individuals involved in activities requiring use of respiratory protective equipment as specified for selected RWPs utilized during the current 1990-1991 Unit 3 and Unit 4 (U3/U4) outage. .From review of records and discussions with licensee representatives, the inspectors verified that all personnel were fit tested and medically qualified as i required by approved licensee procedure However, contrary to procedure number 0-HPA-060, records reviewed indicated that employees were being ' retrained biennially instead of annually. The inspectors informed licensee representatives that the failure to follow training procedures for respiratory protection program activities was a violation of TS 6.11 (50-250.-251/91-08-01). During discussions with cognizant licensee representatives, the inspectors were 'l

- informed that the current procedural requirement for annual retraining was j

- an administrative erro Previous revisions of 0-HPA-60 required respirator retraining biennially and the licensee's intent following the August 1990 revision was to continue retraining biennially. Before the end of the onsite inspection activities licensee representatives had submitted a Request for Procedure Review to change respiratory retraining from an annual to a biennial frequency. The change request was reviewed and approved on February 28, 1991. The inspectors informed licensee representatives this NRC-identified violation was not being cited because criteria specified in 10 CFR 2 Section V.A of the enforcement policy were me .

I During the onsite ' inspection, the inspectors verified that Form NRC-3 and notices referencing the appropriate 10 CFR Part 19 and Part 20 and licensee documents were posted in accordance with the applicable j regulation. Forms were posted at the FP&L and contractor entrances j to the protected area in view of all employees entering the protected I are No violations or deviations were identifie Form NRC-4 l 10 CFR 20.102(b) requires, under certain circumstances, the licensee to obtain a certificate on Form NRC-4, signed by the individual ;

showing each period of time after the individual attained the age of l 18 in which an occupational dose to radiation was received. This signed and completed form shall be obtained before permitting the .

individual in a restricted area to receive an occupational radiation !

dose in excess of the standards specified in 10 CFR 20.101(a). l The inspectors reviewed licensee records of workers signed on RWPs .

associated with 03/U4 RTD removal to verify completion and  !

maintenance of individual's Form NRC-4, as appropriate. The inspectors noted a completed Fonn NRC-4 on file for all workers as ;

Licensee corrective actions included documenting the event as a radiological incident report (RIR), counseling the individual on procedural requirerrants for working in the RCA, being aware of radiological postings, and various disciplinary actions; the individual was restricted from the RCA and rescheduled for GET; and revising- resin transfer procedures 0-HPS-053.2, 0-HPS-053.3, and 0-HPS-053.4 to require, where practical, posting high radiation areas at waist level. The corrective actions to prevent recurrence were determined to be acceptable. The inspectors informed licensee representatives that this licensee-identified violation would not be cited because the criteria specified in Section V.G.1 of the NRC -

.

Enforcement Policy were me ~

The inspectors noted that based on the depth of review and significance of identified issues, the present audit program was considered a program strength and had contributed to the RP program improvement One NCV concerning the failure to follow RP procedures was identifie Radiological Incident Reporting System The inspectors reviewed the the licensee's internal RP program for identifying and correcting deficiencies and weaknesses related to the control of radiation and radioactive material. The licensee has five categories of RIRs: (1) Type 1- personnel contamination events; (2)

Type 2- HP violations; (3) Type 3- poor work practices; (4) Type 4-personnel monitoring problems; and (5) Type 5- non personnel event During 1990, the licensee identified 712 RIRs. The RIRs were distributed in the following manner:

Type 4 - 403

Type 1 - 214 )

Type 2 - 61  ;

Type 5 - 29

  • Type 3 - 5 l As of February 28, 1991, there were approximately 178 RIRs identified by the licensee. The inspectors reviewed selected Types 2-5 RIRs from Juuary 1990 to February 28, 1991, and did not observe any significant programmatic problems. In cases where licensee-identified ;

deficiencies were observed, the inspectors noted that the rwy-

deficiencies were addressed properly, and as appropriate, a root l cause analysis was performed and corrective actions were take No violatior.s or deviations were identifie l Internal Exposure (83750)

10 CFR 20.103(a)(1) states that no licensee shall possess, use, or N transfer licensed material in such a manner as to permit any individual in l a restricted area to inhale a quantity of radioactive material in any  ;

period of one calendar quarter greater than the quantity which would '

result from inhalation for 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> per week for 13 weeks at uniform concentrations of radioactive material in air specified in 10 CFR Part 20, Appendix B. Table 1, Column CFR 20.103(a)(3) requires for purposes of determining compliance with the requirements of this section, the licensee to use suitable measurements of concentrations of radioactive materials in air for detecting and evaluating airborne radioactivity in restricted areas and in addition, as appropriate, to use measurements of radioactivity in the body, measurements of radioactivity excreted from the body, or any ,

j combination of such measurements as may be necessary for the timely ]

l detection and assessment of individual intakes of radioactivity by exposed individual _

'l e Licensee implementation of air sampling, and annual and/or special whole

! body analyses, and internal exposure assessments for workers conducted t during the current U3/U4 outage were reviewe Air Sampling l The analytical capability of the licensee's air sampling system was !

l reviewed in detail. From discussion with licensee representatives and review of selected servey records, the inspectors noted Cobalt 57 (Co-57) and Co-60 were ti e potential primary contributors to exposure l from airborne radioactive materials. The ins i

' reviewed the lower limit of detection (LLD) pectors for thediscussed licensee'sand I routine sampling volumes and analytical detection limits. Based on  !

routine air sample volume and subsequent counting times, cognizant ,

licensee representatives calculated a LLD of approximately l

'

4.0 E-11 microcuries per cubic centimeter for Co-57/Co-60. The

inspectors noted that the calculated LLD for the licensee's methods
and analytical system was less than 0.5 percent of the Maximum Permissible Airborne Concentration (MPCa) detailed in 10 CFR Part 20, Appendix B Table 1 Column The inspectors noted that the licensee's methods appeared adequate to assess properly, workers'

< internal exposures to airborne radioactive material Licensee records of air sampling results used to evaluate airborne I radionuclide concentrations associated with Unit 4 RTD removal were i

The inspectors reviewed and verified completion of annual whole body counts for selected RPM as recuired. Additionally, 0-HPS-026.1, Decontamination of Personnel, cated July 20, 1990 requires, in the event of a facial contamination, a whole body count after .

decontamination is complete The inspectors reviewed 1990 RIRs

-

detailing individuals reported to have positive facial contamination and verified that whole body counts were conducted in accordance with procedural guidance. Further, from review of the selected whole body analysis records the inspector noted that no positive whole body analyses were identifie No violations or deviations were identifie . External Exposure (83750)

10 CFR 20.101 requires that no licensee shall possess, use or transfer licensed material in such a manner as to cause any individual in a restricted area to receive in any period of one calendar quarter a total occupational dose in excess of 1.25 rems to the whole body; head and trunk; active blood forming organs; lens of the eyes; or gonads; 18.75 rems to the hands and forearms; feet and ankles; and 7.5 rems to the skin of the whole body, l

L 10. Solid: Radioactive Waste Management and Transportation of Radioactive l Materials (86750) Training and Qualification of Personnel The inspectors reviewed the qualifications, training, and experience l of selected personnel responsible for the processing, storage and shipping of low level radwaste and radioactive materials. The inspector noted that radwaste technicians received periodic training l in D0T/NRC regulations, waste license burial requirements, and j operating procedures for the transfer, packaging, and transport of

radioactive material. The most _ recent training workshop was provided i by a waste processing contractor in December 1989. The licensee had I scheduled periodic retraining for radwaste and supervisory personnel l in March 1991. In addition, radwaste personnel had received l specialized computer software program training in waste

' classification, characterization, and radioactive materials shipments in October 1989. The inspectors also noted that selected individuals had received specialized training in hazardous materials, chemicals, waste management, and compliance in 198 In general, the licensee's training program for shipping and transportation was sufficient to instruct radwaste technicians for proper performance of their dutie No violations or deviations were identified.

radioactive material and the activity contained in each package of  !

the shipment in terms of curies, mil 11 curies, or microcurie ,

The inspectors reviewed selected records of radioactive. waste and radioactive materials shipments performed in 1990 and 1991. The l l

shipping manifests examined were consistent with the applicable 49 CFR Parts 170 - through 189, requirements. The radiation and contamination survey results were within the limits specified for the mode of transport and shipment classification and the shipping documents were completed and maintained as require . - Through interviews with licensee personnel, the inspectors determined l

~ _

that the licensee had identified an error in the Dry Active Waste (DAW) data base which was used by the licensee's shipment manifest calculation software. The licensee discovered that Nickel-63 (Ni-63)

was not reported by their vendor analytical laboratory during the last sample collection period in 1989 and thus no scaling factor was included in the data bas A cognizant licensee representative noted that Ni-63 had been a consistently quantifiable isotope'during the past several years and thus, the previous year's scaling . factor should have been used. The omission of Ni-63 affected seven DAW shipments (90-12, .90-13, 90-20, 90-21, 90-22, 90-26. . and 90-28) made in 1990 to the licensee's waste processor. In all cases, the waste classification was not affected. The total amount of Ni-63 that was not reported was 42.45 mil 11 curie The inspectors informed licensee representatives that the failure to report the quantity of Ni-63 in seven radwaste shipments was a violation of 10 CFR 20.311(b)

requirements (50-250,-251/91-01-03). .

The inspectors reviewed and discussed corrective actions previously implemented. t.icensee's actions included: (1) issuance of a revised notice of manifest to the licensee's waste processor and the Florid Department of Health and Rehabilitative Services; (2) revision of radwaste data bases; and (3) revision of shipping documents. The inspector also noted that the licensee requires the radwaste supervisor and the HP/radwaste shift supervisor to review the scaling factor Jata base especially in cases when the new software program flags a nuclide whose scaling factor changed by more than a factor of

Followup radiation surveys of the liners conducted on February 26, 1991, measured contact radiation exposure levels y exceeding 1.5 mrem /hr for the three containers. The inspectors informed licensee representatives that the failure to follow RP # '

procedures for labelling containers was a violation of TS 6.11 (50-250,-251/91-08-04). Licensee representatives stated that the area was posted " Caution Radioactive Materials / Caution Radiation l

, Area," and that a label was affixed to the top of the liners to caution any individual working directly on top of the containers.

'

Radiation exposure information regarding the subject storage area was not on area survey maps nor on postings associated with the insnediate or surrounding storage areas. The inspector noted that the liners were in a heavily trafficked area during the current outage and that the label was required to be visible by employees working with the liners and also by workers working in the inanediate vicinit One violation of TS 6.1'1 for failure to maintain adequate labelling for resin liners was identifie High Radiation Area RWP Control TS 6.12.1.a requires, in part, each high radiation area in which the intensity of radiation is greater than 100 mrem /hr but less than 1000 mrem /hr to be barricaed snd conspicuously posted as a high  ;
