Recurrences Evaluation: @ Dump Review

Marco Garlasché

Recurrences Evaluation: Updated

Accident recurrence not needed, provided component responsible confirms 100% success of prev. Maintenance w.r.t. failure

Marco Garlasché

1 BSW2-3 is single component

2 max value governs maintenance recurrence

3 sum of recurrences determines accident frequency

4 Discussed with J.Hansen. Acceptable value of venting to upstream & downstream sectors

5 Valve blocked: 500 valves, 15 years, 2 failures

6 Value given by St. Burger is 1+1+1

7 For camera and lights, lifetime is 2000hrs:

1/2000hrs+1/2000hrs+1/2000hrs=3/2000hrs= 3.3 failures per Injection_year (hp: 275days, 24hrs per day)

8 Value cannot be estimated Parameter to be used by RP to reduce accumulated dose
