Lessons Learned from Pilot.
What is a Tiger Team?
3 a team of undomesticated and uninhibited technical specialists, selected for their experience, energy, and imagination, and assigned to track down relentlessly every possible source of failure in a spacecraft subsystem
- 1964 - Society of Automotive Engineers, Third Annual Aerospace Reliability and Maintainability Conference A Tiger Team consists of a group of experienced reviewers who are focusing on a single application in order to greatly decrease the review time of that application.
for Topical Reports
How does it work?
4 Regular Review - one primary reviewer and one peer reviewer for subject area in a Topical Report Primary Reviewer - 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> (~ 85%)
Peer Reviewer - 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br /> (~ 15%)
Tiger Team Review - two primary reviewers and an additional peer reviewer for a subject area in a Topical Report Primary Reviewer 1 - 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> (~ 46%)
Primary Reviewer 2 - 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> (~ 46%)
Peer Reviewer - 35 hours4.050926e-4 days <br />0.00972 hours <br />5.787037e-5 weeks <br />1.33175e-5 months <br /> (~ 8%)
Increased man hours results in faster decision making.
When could you use a Tiger Team?
5 1.
The Topical Report has a high priority.
The applicant is aware of the increased review cost.
The NRC is willing to commit the resources.
2.
Two or more experienced technical reviewers available.
Necessary to reach technical decisions faster.
3.
The applicant is able to support the accelerated review schedule.
The applicant can support the extended audits, calls, and RAI responses.
When shouldnt you use a Tiger Team?
6 1.
A Topical Report in a brand new technical area.
For brand new technical areas, the NRC often needs to reach new conclusions.
2.
An n-th of a kind Topical Report.
Regular review may already be expedited (i.e., no hard technical decisions, only documentation).
3.
When a reduction in the review time is unlikely or if the possible reduction in the review time ( 50%) is not worth the extra resources.
WCAP-18240 - Westinghouse Thermal Design Procedure 7
Review Highlights 1.
Two primary reviewers (Joshua Kaizer, Reed Anzalone)
Each spent substantial hours reviewing material before first audit.
2.
Expanded Audit for Understanding 2 days audit, 2 days writing draft SE Applicant had draft RAIs at audit exit.
3.
RAI Clarification Call 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> call, updated SE real-time 4.
Completed draft SE in 6 months, on track for under 1 year review time (50% reduction).
Conclusion 8
1.
Expanded scope audits and real-time SE updating are great time savers overall!!!
2.
A Tiger Team can result in significantly reduced review times.
3.
The Tiger Team is one tool, and depending on the Topical Report, it may be the right tool.
