US-DPRK NEXT STEPS WORKSHOPJanuary 27, 2003 Washington DC • Dismantlement and Cessation of DPRK Nuclear Capacities: Living with Uncertainty Elwood Gift • Senior Engineer, Oak Ridge National Laboratory, Dept. of Energy, January 27, 2003.
LIVING WITH UNCERTAINTY After we have a North Korean Declaration on their uranium enrichment program
Should we be content? • What does the Declaration consist of? • Enrichment facilities only? • Mining, conversion, and uranium storage facilities included? • Centrifuge and component facilities included? • Nuclear material produced? • Do we have access? • Inventory in Declaration? • Can its completeness be verified? • Production records? • Records of imports and their disposition?
Can the Declaration be confirmed? • What are the inspectors rights of access? • How often? • With or without prior notice? • How many persons? • How intrusive can they be? • Sampling and analysis rights? • Is the Declaration complete enough for meaningful production analysis?
What are the goals? • A nuclear weapons free North Korea? • A nuclear (uranium) production free North Korea? • Probably not a nuclear free North Korea? • Is facility dismantlement a goal? • How much confidence do we need?
Can we find an undeclared gas centrifuge enrichment facility? • What is its production capacity? • Possibly 25 kg HEU/year • What are the observables? • Power requirement: < 200 Kw • Natural uranium requirement: About 5500 KgU/year, about 4 30B UF6 cylinders per year • Size of building: < a Safeway grocery store • Is it underground?: Probably • Emissions: Virtually none
