COMMISSIONING AND OPERATION • AAC Commissioning/Operations staff: • Led and supervised commissioning and initial operation including in-service inspection and maintenance. • Accepted systems turnover from construction • Supervised commissioning for compliance with approved procedures • Evaluated commissioning completion to declare availability for service • Supervised operations support programs: shift operation, maintenance, chemistry control, materials control, radiation protection, industrial safety, safety and licensing, planning and scheduling • Assist in staff training • Customer provided full complement of operation staff • AAC staff transferred leadership and supervision to customer’s staff gradually as a function of their demonstrated capability
OPERATIONS STAFFING PLAN • AAC developed staffing plan along with specific position specific requirements • Covered full complement of operations staff trained and available for commissioning and operation at least 18 months prior to Unit 1 connection to grid • Supported the customer to select personnel • Developed and conducted training program for key operations staff
OPERATIONS TRAINING • 90 key Romanian staff identified for training in Canada. • Management and senior supervisory 10 • Shift operations 50 • Maintenance 10 • Computers 4 • Technical support 12 • Other 4 • Training durations ranged from 4 to 24 months depending on job requirement • Classroom training in CANDU technology, skills training, in-plant training in Canada, and simulator training. • On-the-job coach and mentoring during commissioning and early operation
Unit 1 Turnover to Operations • Assessment of all structures, systems and components for compliance with design requirement • Assessment of each operations department along with recommendations to fill any gaps • Following formal turnover of Unit 1, WANO conducted a Peer Review in July-August 1997. One of the key strengths noted was: • “ A very knowledgeable and professional management team is established. The management team willingly embraces new ideas, and is highly motivated to achieving excellence in the operation of the plant.” • Unit 1 operated by Romanian operating staff since in service date has an excellent safety and performance record • Lifetime capacity factor for Unit 1 over the past 10 years is around 87%
