Results of Design Reviews Hank Drumhiller INPO, EN ADM September 26, 2000

Background Design Engineering is a focus area Reviewed six-months of evaluations 12 INPO 5 WANO 5 Design Reviews Plan 10 Design Reviews in 2001

Areas for Improvement 26 EN AFIs One plant had no EN AFIs Two plants had three EN AFIs

Engineering AFIs Largest number of EN AFIs were for: Less than adequate design engineering product quality (18%) System engineering was main focus: Monitoring and trending (15%) System improvement plans (7%)

AFI Causes Largest single contributor to EN AFIs: Ineffective engineering management (20%) Management fails to: establish or communicate standards and expectations hold engineers accountable monitor engineers’ work

AFIs Causes Largest problem area facing engineering: Less than adequate engineering work management (19%) and Less than adequate work prioritization (14%) Prevents engineering and the site from getting the right work completed

AFIs Causes Another major contributor to AFIs is: Less than adequate engineering infrastructure Inhibits engineer’s ability to do work Reduces effectiveness of engineering programs, processes, and procedures

AFIs Causes Other major causes identified were: Adequacy of root cause analyses and effectiveness and timeliness of corrective actions (10%) Engineering turnover (6%) Verbal communication within engineering (6%)

AFI Examples Ineffective management of some engineering activities contributed to delays in meeting outage milestones. Changing priorities, resource demands, budget constraints Emergent issues and personnel changes Engineering schedule not manloaded Engineering internal and external communication weak No plan to reduce engineering backlog

AFI Examples Deferral of design changes, increased backlogs, and untimely updating of calculations and design basis information. Informal EN work management Weak performance indicators No review of low priority work Project resources aren’t estimated or monitored Management doesn’t hold engineers accountable Management didn’t fill open positions

AFI Examples Modifications have been installed outside design process and untimely updates of design products. Loss of configuration control Cumulative effect of minor changes is unknown No process for abandoned equipment Management assumed risk of regulatory action Lack of verification in fuse program No guidance for updating calculations

AFI Examples Calculations supporting design basis aren’t retrievable and assumptions used are not documented or justified. Database created to show links didn’t include all calculations supporting tech spec or FSAR No standard for pipe stress or hanger calculations Old vendor info supporting calcs can’t be located Design basis reconstitution on hold Limited engineering involvement with industry

AFI Examples Calculations for AOVs are not in place resulting in uncertainty that critical AOVs will operated as designed. Lack of management focus Reliance on AOV performance and testing Failure to use industry OE

Conclusions Continue focus on Design Engineering Management effectiveness Engineering work management & priorities Maintaining strong infrastructure Expectations, accountability, & communication
