Challenges

* Commission policy on priorities -

domestic partner requirement

* Congressional direction to accelerateNext Generation Nuclear Plant

* FY 2008 and FY 2009 budget foradvanced reactors

* Hiring/developing knowledgeable staffand contractors

* Developing regulatory infrastructure

9

Advanced Reactor Program -

Project Management Infrastructure

o Separate from ongoing LWR licensing-Consolidate licensing projectmanagement function in, NRO for LWRsand Non-LWRs

* Office of Research continues researchon technical bases and providesexpertise to support licensing reviews

Next Generation Nuclear Plant(NGNP) Licensing Strategy

* Report to CongressAug 7, 2008

* NRC-DOE Licensing Strategy* NRC needs for technical infrastructure

development including analytical tools& data

* Resource requirements

14

Non-LWR Technical Infrastructure

* NRC does not currently have thetechnical infrastructure to support reviewof non-LWR reactor designs

* NRC infrastructure was developed andrefined over the past: 40 years for LWRs

* We need to develop similar capabilitiesfor HTGR & LMR

15

Technical Tools Strategy

* Applicants are expected to conduct theR&D needed to establish the safety basisfor the proposed design

* Pre-application reviews will be used toprovide feedback to applicants on policyissues and needed R&D

* Staff will utilize licensee-generatedinformation and leverage internationalinformation to the extent practical

16

NRC non-LWR Confirmatory Analysis

NRC should develop independentcapability to assess the safetyperformance of non-LWRs

-Started development of some of theneeded tools for HTGR

Data for code validation will beneeded

• Staff will identify when NRC-fundedconfirmatory research is recommended

17

NRC HTGR Confirmatory Analysis

o Fuel performance- MIT Cooperative Agreement-DOE- International collaboration

• Thermal fluids & Accident analysis- MELCOR-CFD

* Nuclear analysis- PARCS

18

NRC HTGR Confirmatory Analysis

• Materials performance-High temp materials & graphite

• PRA quality and use-ASME developing PRA quality

standard for advanced reactors

* H 2 production facility hazards analysis

19

NRC HTGR Confirmatory Analysis

* Data required to validate NRC codeswill be obtained from existing integraltest facilities, where possible

* Need for additional integral testfacilities will be assessed duringNGNP & PBMR pre-application reviews

-We may need an integral facility inUSA to address emerging issues

20

Potential Collaborations* CSNI

" IRSN and CEA, France" N NR, S. Africa" European Commission (EC)* Germany

' United Kingdom• Japan Atomic Energy Research

Institute" China" Universities• Department of Energy

21

Other designs

* NRC Skill set and tools are lacking forLMR and hydride reactor

* With adequate resources and staff, itwill take at least 5 years to developindependent capabilities for LMRFor PBMR, RES will not be able provideindependent capabilities for COLreview until 2013

22

Concluding Remarks

• NRC could meet its commitment tosupport 2005 EPAct, provided:

-DOE selects an NGNP design andoperational envelope in early 2009

-DOE accelerates NGNP technologydevelopment

- pre-application review begun in 2010- policy/technical issues resolved by

2012

- Sufficient NRC resources available

23

Concluding Remarks

• Implementation poses challenges toNRC- Developing necessary skill set &

infrastructure for the review- Adequate funding and personnel

- Resolve technical & policy issues- Interact closely with DOE andapplicants to ensure adequacy ofdata and tools

- Participate in internationalcollaborations
