Public Meeting Summary LaSalle County Station l
October 27.1998. Manaaement Meetin_g Summary:
The licensee provided the NRC representatives with a handout (Enclosure 2) and discussed the information contained in the handout during the meeting. The discussion centered around the performance of Unit 1 since startup, the material condition of LaSalle, and the status of the outage activities on Unit 2. Specifically, the areas discussed relating to Unit 1 performance included the plant operating history, human performance, the material condition and processes related to improving material condition, and the plans for an upcoming Unit 1 outage. Topics discussed related to Unit 2 included an overview of the outage scope and schedule. The licensee also discussed plans for long-term station improvements.
The licensee specifically provided the following information:
The licensee discussed the Unit 1 operating history since startup, including information related to the reactor core isolation cooling system rupture disc event which occurred on September 17,1998. The licensee used corporate and vendor resources to improve the rupture disc event investigation. The licensee concluded that the improvements in the corrective action process and procedures which were implemented during the extended Unit 1 shutdown resulted in an improved event investigation.
Human performance continued to improve at the station and operations personnel errors decreased. In addition, the licensee indicated that the operations personnel error rate, although still greater than industry standards, was decreasing. Other department event free clocks indicated improved performance and operations performance showed the most improvement and lowest error rates.
The licensee indicated that material condition improved at LaSalle Station as a result of the work done during the forced outage. However, material condition improvements 5
were still necessary. The licensee also believed that the processes used to control and p!an work at the station still needed improvement. The licensee indicated that the 12-week work schedule was a key to the station's ability to get more work done and more resources would be used to plan work in a more timely manner (Live Time Planning).
Several areas showed improvement including the percent of contaminated floor space, the number of operator work-arounds, and the number of control room distractions.
The licensee provided an overview of the Unit 1 planned outage which was scheduled for December 5,1998, and would last less than 7 days. Approximately 330 work request tasks were planned and the majority of the tasks were related to Technical Specification surveillances.
I The Unit 2 outage scope was based on the same screening criteria that were used to define the scope of the Unit 1 forced outage. The licensee indicated that the lessons leamed from the Unit 1 forced outage were incorporated into the planning for the Unit 2 outage. All design changes completed on Unit 1 were reviewed and incorporated into the Unit 2 outage scope by the licensee. In addition, the licensee reviewed the operations issues that were encountered during the startup of Unit 1 and incorporated the lessons learned into the plans for Unit 2. The Unit 2 outage scope included 373 design changes, approximately 4,174 preventive maintenance / surveillance tasks, and 1,427 corrective maintenance tasks.
The licensee projected that Unit 2 would be at 100 percent power by June 1,1999.
Long-term improvements at LaSalle would be based on the Station Business Plan with the goal being top-quartile performance by 2001. The licensee's Station Business Plan also addressed performance improvements for all departments at LaSalle.
The licensee discussed the need to improve the capability to resolve technical issues, citing examples where troubleshooting activities did not meet management expectations. Improvements would be realized by increased use of external support, such as corporate and vendor experience, and increased basic technical knowledge of the engineering staff.
During the discussion, the NRC staff communicated the following questions or items for consideration:
The NRC staff questioned the licensee about the extent of the material condition improvements. The NRC staff requested that in future meetings the licensee discuss the corrective actions to improve the work process, the actual progress seen on material condition improvements, and the licensee's current characterization of material condition at LaSalle Station.
The NRC staff inquired regarding the number of design changes that were being completed to bring the plant back into compliance with the design and licensing basis.
The licensee indicated that approximately 30 to 35 percent of the modifications being completed on Unit 2 were necessary to bring the plant into compliance.
The NRC staff inquired regarding the licensee's detailed schedule for the Unit 2 outage.
The licensee indicated that the schedule would be provided after it is generated. Any meetings to discuss the outage schedule and scope would be arranged as necessary.
The NRC staff was interested in the long-term improvements in the licensee's engineering organization given the problems that the licensee was having with the engineering capability prior to the dual unit shutdown and the current issues related to the resolution of technicalissues. The NRC requested that the licensee address the long-term improvement plans for engineering at LaSalle during the next public meeting.

i The NRC cautioned the licensee about the potential impact of the Unit 2 restart activities, particularly the planned integrated testing, on the operators' ability to operate Unit 1. The licensee indicated that the plans related to control room operations would be addressed at the next public meeting.
