Within the scope of this review, the following was identified:

- The licensee has initiated action to improve the overall quality'of audits.and make them more performance based. All members of the QA group attended a training course on performance based audit method : The licensee revised procedures to highlight the need to thoroughly review recurrent items and perform root cause determination The licensee is responding to SECY-87-220, Assurance of Quality, j dated August 31, 1987. Licensee audits will review management effectiveness to address this SECY documen The licensee performed two audits of the radiological controls program in 1988. In order to continue to monitor the performance of the radiological controls program, the licensee plans to again-perform two audits of the radiological controls program in 198 The following was discussed with licensee management:

-

The licensee has in place a program entitled " Job Observation Program." This program provides for personnel to observe on-going activities and document positive observations or poor practices needing improvement. This program is a good initiative.for self-identifying and initiating corrective actions for performance deficiencie Inspector review, however, indicates continued problems with documentation and resolution of identified problems (e.g., procedure violations.). For example, a job observation made on May 31, 1989, identified problems with personnel not adhering to a radiation work permit. Personnel were observed cutting contaminated material in apparent violation of the applicable radiation work permi At anythe time of this information inspection, regarding thisjob observation or what, if any,the licensee was u short and long term corrective actions had been taken. The inspector noted that the job observation had been signed by a radiological controls supervisor and that the observation was to be i routed to the department manager. No information was presented to ,

indicate that this matter was resolved by managemen t

, The inspector noted that previous job observations had identified personnel not adhering to radiation protection procedures. Also, the matter of the licensee not being able to provide corrective actions for self-identified problems was discussed with the licensee in July 1988 Reference NRC Inspection Report No. 50-309/88-12 and in Novem er 1988 (Reference NRC Inspection Report No. 50- 09/88-80).

' Since the licensee was unable to provide any information on the apparent procedure violations identified, the inspector was unable to determine if the licensee met all criteria for non-issuance of a

. Notice of Violation as described in Appendix B of 10 CFR Part 2. The

'

licensee indicated information would be gathered to address the inspector's concern. The inspector indicated that recent job observations were considered unresolved pending review of licensee t information (50-309/89-15-01).

5.0 Organiza' tion and Staffing )

i The-inspector. reviewed the organization and staffing of the radiological controls group. The review was with respect to criteria contained in applicable Technical Specification Within the. scope of the review, no violations were identified. The following matters were discussed with the licensee's representatives:

- The licensee is attempting to strengthen the technical capabilitie and industry experience levels of the radiological controls group by hiring personnel from outside the licensee's organization. As an example, a dosimetry supervisor was recently hired with considerable experience from outside the licensee's organizatio The licensee's Radiation Protection Manager has indicated a desire to resign. A replacement has not yet been selecte The licensee's Radiological Support Supervisor responsible for managing the ALARA 3rogram, the Internal Dosimetry Program, the External Dosimetry )rogram, the Respiratory Protection Program and the Hazardous Waste Program recently resigned. The individual selected to fill the position has limited pract cal experience in reactor radiological controls program The licensee recently upgraded a radiation protection technician to fill the. position of ALARA coordinator. The technician has limited experience in the area of ALARA and limited formal training in ALARA Programs. An individual previously in this position was rotated into another positio The licensee's representatives indicated a review was currently underway to reorganize the Radiological Controls Group. The licensee is considering reorganizing the Radiological Controls Group to improve its management and overall effectivenes . 8

6.0- Radiological Controls Program Improvements 6.1 Background The NRC's Systematic Assessment of Licensee Performance (SALP), dated January 5, 1989 (SALP Report No. 50-309/87-99) for the Maine Yankee Atomic Power Company, identified a number of programmatic weaknesses needing licensee attentio During this inspection, the inspector reviewed the licensee's actions on the identified weaknesses. The inspector also reviewed the-licensee's plans for improving the overall Radiological Controls Progra .2 Findings The inspector's review and discussion with licensee management indicate actions are planned or underway to improve the overall quality of the Radiological Controls Program at the Maine Yankee Nuclear Statio Support for the improvement was clearly indicated by inspector discussions with the licensee's senior managemen The following initiatives to improve the quality and effectiveness of the Radiological Controls Program were noted:

- The licensee has developed a draft Radiological Controls Improvement Program. The draft plan includes 48 major programmatic items selected, in part, to improve performance relative to the seven assessment criteria considered in NRC SALP assessment The plan also includes 16 ALARA initiatives to improve performance in the area of ALARA. The plan has been distributed for review and comment. The plan is scheduled for approval around the end of September 1989. Plan elements include reorganization of the Radiological Controls Group and performance of a review of the entire Radiological Controls Program by an outside consultan The licensee is planning to reorganize the Radiological Controls Group to improve Radiological Control Program management and effectiveness. The reorganization is scheduled for October 1, 198 The licensee has completed significant clean-up of the backyard areas. More work is on-goin t - In order to reduce general area radiation levels, the licensee has initiatu a flushing program to flush localized crud deposits from pipin The licensee is developing a loop flush procedure to flush primary loops during cool down for the 1990 outag i

-The reviews in this area were with respect to criteria contained in 10 CFR-20,' Standards ~ for Protection Against Radiation, applicable licensee

. procedures and standard industry practice Within the scope of the review, no violations were identified. However, the following matters were brought to the licensee's attention:

-

Housekeeping in portions of the radiological controlled area was considered poor.. Observation _identifiec: dirty and dusty conditions, balls of tape discarded on electrical trays and plastic trash bags stuck behind pipin The licensee has a radwaste storage bunker in the backyard area of the facility. Inspector reviews noted water inside the bunker. The sump pump-for the bunker was broken. Tne licensee's personnel could not )rovide the inspector information regarding radioactivity levels of tie water or-information on the acceptability of allowing the water to remain in'the bunker. The acceptability of this matter is i

unresolve (50-309/89-15-02).

- The licensee maintains an interim low level waste storage facility on site. The facility is used to. store radioactive material prepared for transport. Ins)ector review indicated that there was limited radwaste stored in tie facility and dose rates on the outside of the facility were negligibl o

However, it was not apparent that adequate procedural ' controls.were established to ensure compliance with 40 CFR 190 offsite dose limits. The licensee indicated this matter would be reviewed. The inspector indicated this matter would be reviewed during'a subsequent inspectio A sign warning personnel not to remove material from the spent fuel storage pool due to radiation hazards was stuck behind'some piping and obscured. There were no other signs around the pool warning of this hazar Tours throughout the radiological controlled area identified numerous examples of hoses and lines running from clean areas into contaminated areas. The hoses and lines were not secured to prevent them from being' inadvertently pulled from the contaminated areas into the clean area Numerous 55 gallon drums of slightly contaminated oil were^ store outside the facility under a small roofed structure. The drums were showing some rusting and were in close proximity to storm drain The licensee plans to burn the oil in boilers and has apparently .

received authorization for the burning. The drums, however, have been in the area for an extended period of tim A locked High Radiation Area' Door in the lower elevation of the auxiliary building, leading to the letdown area, exhibited about a 6 inch to 12 inch gap from the floor. It was not apparent that the door would preclude unauthorized entry into the letdo::n are A thecontractor individual backyard area (one was not of three)
