50-374/93003(DRSS))

Areas Inspected: Routine announced inspection of the licensee's radiation protection (RP) program (Inspection Procedure (IP) 83750), including changes in organization, internal exposure control, external exposure control, maintaining occupational exposures as-low-as-reasonably-achievable (ALARA),

radiological events, and review of concerns received at the Region til Offic _Results: One non-cited violation for a licensee identified event involving a high radiation area not properly barricaded and posted. The station's enhancement to the Engineering and Construction (ENC) department with an ALARA coordinator to aid in the processing and facilitating of RP reviews and RP department interface was viewed as an improvement to the overall station-radiological controls program. The station Quality Verification (QV) group-continued to perform in the field observations of RP procedural compliance with substantive findings and is considered a licensee strength.- The station

The inspector also interviewed other licensee personnel in various departments in the course of the inspectio * Indicates those present at the exit meeting on January 8, 1993. Changes (IP 83750) -

The RP department has undergone minor personnel changes since the-last '

inspection. One member of the technical health transferred to-Cresden Station. This individual physics ' grnup has-s responsibilities, which included calibration of an assortment of monitors and meters, and completion of radioactive waste shipment documentation, will.be dispersed between two other members of the technical health physics -

staff. A corporate health physicist-is also temporarily assigned to the-station to aid in the turnover of these activities. The inspector noted-no negative effects on the RP department.as a resultiof this chang No violations or; deviations were identifie g.---.._., y .ay-. '- --

. Aud_tts and Appro.sals (IP_837 M1 The inspector reviewed recently completed audits and field monitoring reports which focused on RP issue The first audit reviewed was audit number 01-92-03, a full audit of the Technical Services department which includes RP activities. 1he audit identified one concern with respect to the evaluation process for some lead shielding packages used during outages. The audit identified an isolated case where lead was hung without a thorough engineering review of the offects the lead may have on systems in the area. The recommendations and corrective action appeared to address the root cause of the occurrence and corrective actions were still ongoing at the time of the inspectio _

lhe second audit reviewed was number 01-92-006, which focused on vendor laundry activities of the station's protective clothing. The audit team included a member of the station RP department and a member of the corporate RP staff. The results of the audit concluded that the vendor was performing adequate segregation of laundry to avoid possible cross contamination from other user stations and good RP practices were used overall, field monitoring reports (fMRs) reviewed addressed observations made specifically to focus on RP procedural adherence in the field. The FMRs high light both good and bad practices observed. Several good practices were noted and only minor bad observations were identified, such as down postings and improper wearing of secondary dosimetr Overall, the FMR program continues to work well in identifying potential weak areas with RP procedural compliance, and corrective actions to QV concerns are immediately resolve The inspector found the findings of the above mentioned audits and FMRs to be substantive and technical in origi Overall, the station QV -

department continues to perform as a licensee strengt No violations or deviations were identifie . Jnterna]_[y.posure Comols (IP 8R101 The inspector reviewed the results of the licensee's whole body counting system's calibration and daily quality control checks. The yearly calibration performed by the vendor providing the equipment and reports were reviewed and found to be accurate and in order. Quality control checks were performed according to station procedures and all checks reviewed fell within acceptable limit No violations or deviations were identifie .

No violations or deviations were identifie . [.p.nlamination Control (IP 83750)

Contaminated area in the station did not significantly increase since the last inspection. The station is continuing its policy to address source term reduction efforts prior to performing decontamination of large areas which are contaminated with low levels (< 1,000 dpm/100cm') ,

of contaminatio '

'

'

Personnel contamination events (PCEs) recorded for 1992 totaled 235 versus a goal of 295 for the year. The station's 1993 PCE goal is 150,-

12 PCEs had occurred for the year at the time of the inspectio No violations or deviations were identifie . Maintainina Occupational Exposures ALARA (IP 83750)

Total station dose for 1992 was 1,067 person-rem versus a goal of 1,213 .

person-re Current exposure data for the Unit 1 outage was continuing to be below projected goals. Exposure totals at the time of the inspection for the Unit 1 outage were 360 person-rem, with a projection that the final totals for the outage will be less than the outage goal of 390 person-rem. The completion of this outage under the established goal appears to be the realization of station efforts to involve contract personnel in the early- stages of ALARA planning < incorporating -

improvements from lessons learned in previous outages, and successful hydrolazing activities to reduce general and local area dose rates. The station's exposure goal for 1993 is still undetermined due to-outage work scope uncertainties for the 1993 fall. Unit 2 outage.

l The inspector reviewed the changes made to ALARA staffing during the Unit 1 outage with respect to the enhanced interface of the contract staff and the RP department. The ENC group has hired on a full time ALARA coordinato This individual's responsibilities include providing the early ALARA reviews of work to be performed by the contract staff and subsequently-perform the associated ALARA pre and post job reviews for such activities. Overall, the inclusion of such an individual has been_an improvement and the inspector will continue to follow the' -

On November 11, 1992, at 1730 hours0.02 days <br />0.481 hours <br />0.00286 weeks <br />6.58265e-4 months <br /> the Unit I reactor building 673'

elevation watertight door leading into the Low Pressure Core ,

Spray / Reactor Isolation Cooling Room (LPCS/RCIC Room) was discovered tied open. This door allowed access to high radiation areas, and the entry did not have the appropriate postings and barriers in place. Tbn open door was discovered by radiation protection technicians (RPTs)

performing their routine surveys in the area. The door had apparently been tied open by a non-licensed operator who was routing a drain hose to the reactor building northeast drain sump. This was a violation of 10 CFR 20.203(c), which requires a conspicuous posting identifying the high radiation are Corrective Actions:

Immediate corrective actions were taken by the RPIs by properly posting and barricading the entrance to the high radiation area, and informed the shift engineer in the control roo Other corrective actions included communication sessions with operating staff to reinforce the need to contact RP when tieing doors open or moving radiological posting The inspector discussed specifics of the event with licensee staff and informed the licensee that due to their identification of the violation and prompt and long term corrective action efforts, that the event would not be cited as the criteria in Section Vll.B of the Enforcement Policy had been satisfied. This LER is close One non-cited violation was identifie . Concern Reylew: AMS-Rill-92-A-0145

[lackaround:

A concern was received at the Region Ill Office in which the individual expressed concern with multiple examples nf inadequate RP procedures at multiple Commonwealth Edison stations. The specific concern with LaSalle station involved the individual's entrance whole body count showing a positive identification of Cr-51. The individual was concerned that since the Cr-51 was detected during his entrance whole body count, could his home be contaminated. In immediate response to the concern, the Region dispatched two inspectors to perform independent measurements at the individual's home to ascertain if contamination existed within his home. The results of the independent surveys were negativ Station Review:

The inspector reviewed the whole body count system's calibration and procedure records used during the time frame in which the concerned

individual started work at LaSalle Stction. All reviews indicated that the whole body count system was functioning correctly and that the RP staff involved with the incident at the time performed all actions ,

accoding to station procedures. The taspector reviewed the actual 1 whole body count records and determined that the identification of the Cr-51 photopeak was an error. The associated error with the identified peak was greater than fifty percent. Licensee staff agreed with this assessment that the identification was an erro findinas: l The LaSalle Station aspect of this concern could not be substantiate The inspector discussed possible changes to current station procedures to help preclude recurrence of such false identification, and specific ,

actions RPTs should take if such suspect identifications occur in the-future. However, the overall concern will remain open until concerns at two other Commonwealth Edison stations can be resolve No violations or deviations were identifie ]

1 Tours During the course of the inspection the inspector made several tours of the radiologically controlled area. The inspector also observed several ongoing work activities during the inspection. All radiation monitoring ,

equipment observed during the tours were in good working order and current calibration. Minor posting and housekeeping problems observed ,

by the inspector were isnmediately resolved by licensee staf No violations or deviations were identifie . Exit Meetina The scope and findings of the inspection were discussed with licensee representatives (Section 1) at the conclusion of the inspection on January 8, 1993. Licensee representatives did not identify any documents or processes reviewed during the inspection as proprietar Specific items-discussed at the meeting were as follows:

• -

The non-cited violation. associated with LER-92-014 concerning a high radiation boundary violatio * The initial findings of the concern review.

!

l *

The effectiveness of the addition of ALARA coordinating staff to the ENC group.

l The good performance of the station during the current Unit 1
