Can the Spread of Nuclear Weapons be Stopped?:  Can the Spread of Nuclear Weapons be Stopped? ◘ Fermi National Accelerator Laboratory November 1, 2006 ◘ Wolfgang K.H. Panofsky During Cold War:  During Cold War Deter with nuclear Triad: ICBM’s, Strategic Bombers. SNBM’s Nuclear war fighting abandoned in plan MAD Mutual Assured Destruction The Cold War is over -- but…:  The Cold War is over -- but… Current Doctrine Deter, assure, dissuade, defeat Pre-empt, with nuclear weapons if necessary “all options” open “capabilities based,” not “threat based” Nuclear weapons play “smaller role” Adaptive planning NUTS Nuclear Use Target Selection Nuclear Weapons Risks Remain:  Nuclear Weapons Risks Remain US – Russia nuclear weapons release Regional Conflict (e.g. India and Pakistan) Acquisition of Nuclear Weapons by Terrorists Nuclear Weapons Proliferation Risk = Probability x consequences increased decreased This Talk Not addressed in this talk Nuclear Terrorism and Nuclear Weapons Proliferation are not the same:  Nuclear Terrorism and Nuclear Weapons Proliferation are not the same States can be deterred. Terrorists can not. No evidence that new proliferant states are greater or lesser risks for transferring nuclear weapons or the tools to make them to terrorists. Nonproliferation – a nonpartisan goal:  Nonproliferation – a nonpartisan goal Presidential Debate: September 30, 2004 Mr. Lehrer: “…so it is correct to say that if somebody’s listening to this, that you agree…the single most serious threat you believe –both of you believe is nuclear proliferation.” Mr. Bush: “I do –in the hands of a terrorist enemy.” Mr. Kerry: “Weapons of mass destruction, nuclear proliferation.” …but… In the History of Mankind, all newly developed technologies:  In the History of Mankind, all newly developed technologies have been “dual purpose” have spread over entire globe This precedent must be broken for nuclear weapons Knowledge is not a bar to proliferation today Cornerstone of Nonproliferation Regime is Nuclear NonProliferation Treaty (NPT):  Cornerstone of Nonproliferation Regime is Nuclear NonProliferation Treaty (NPT) Came into force 1970 Signed and Ratified by all Nations except Israel India Pakistan North Korea withdrew Review Conferences every 5 years Made a Treaty of Indefinite Duration at 1995 Review Conference The NPT Bargain :  The NPT Bargain Nuclear Weapons States (NWS) and Non-nuclear Weapons States (NNWS) US, Russia, UK, China and France are NWS NWS do not give NW or NW tools to NNWS NNWS do not receive such material The NPT Bargain(continued):  The NPT Bargain(continued) NNWS have “inalienable right” to nuclear power. NWS work in good faith toward prohibition of NWs and General Disarmament (no specified timetable; implication is to deemphasize role of NW in international relations NNWS must negotiate Safeguards with IAEA Slide11:  United States Soviet Union United Kingdom France China Israel India South Africa Pakistan Belarus North Korea Belarus, Ukraine, Kazakhstan and South Africa became NNWS Ukraine Kazakhstan NPT in force Number of States with Nuclear Weapons 1970 “I am haunted by the feeling that by 1970, unless we are successful, there may be 10 nuclear powers instead of 4, and by 1975, 15 or 20.” John Kennedy, 1963 Rate of 1 new NWS every 5 yrs Historical Summary of Military Fissile Material & Nuclear Weapons Programs:  Historical Summary of Military Fissile Material & Nuclear Weapons Programs Nuclear Weapons Programs begun before 1970 when NPT came into force, succeeded and are still ongoing United States Russia United Kingdom France China Israel India Sweden Canada Australia Egypt Argentina Brazil Romania South Africa Spain South Korea Spain Switzerland Taiwan Libya Yugoslavia Historical Summary (cont’d):  Historical Summary (cont’d) Italy Japan Germany Norway The Bad News:  The Bad News The Non-Parties to NPT (Israel, India, Pakistan, North Korea) Latency: Capability of NNWS versus Intent NW policies of NWS U.S. redesign efforts Only China proclaims “No First Use.” U.S. pre-emptive policies The physical facts: Uranium Isotope enrichment & Plutonium reprocessing can be part of peaceful power program --- but: Enrichment & Reprocessing can shorten lead time to acquire NW after withdrawal from NPT Slide15:  NWS NNWS Conversion Nuclear Power Nuclear Weapons Nuclear Power Enrichment Spent Fuel LEU ? Reprocessing HEU LEU LEU Spent Fuel Pu ? Reprocessing HEU, PU Uranium Ore The Fuel Cycle Under the NPT IAEA Safeguards Slide16:  INTENT TECHNICAL CAPABILITY OF NNWS IRAN BRAZIL “Latency” or likelihood of acquiring nuclear weapons JAPAN Brazil:  Brazil 1951 (Dual Purpose) Brazil establishes National Research Council Swimming Pool Research Reactor fueled by HEU Brazil bought 625 MWe “turnkey” reactor Brazil (continued):  Brazil (continued) Military 1970 Brazil military government Six 1.3 GWe reactors by 1998 Attempts to import European centrifuges 1980 Three parallel military programs Air Force – laser enrichment Army – natural uranium graphite reactor Pu Navy – centrifuge program Brazil (continued):  Brazil (continued) Peaceful Program 1988 Brazil approves new Constitution: no nuclear weapons ~1990 Argentina and Brazil elected civilian Presidents 1991 Argentina and Brazil terminate weapons programs and signed mutual “peaceful uses” treaty, establishing bilateral monitoring agency Brazil (continued):  Brazil (continued) 1994 Quadrilateral Agreement: Argentina, Brazil, bilateral agency, IAEA But centrifuge program continues. Domestic design more capable than P-1. Claimed purpose: Prestige, Independence; but large hydropower resources Iran:  Iran 1957 – 1979 1957 US-Iran Nuclear Cooperation agreement 1968 Iran signs NPT; ratified in 1970 Plans to construct 23 nuclear power plants by 2001!

Iran not fully cooperative with IAEA Safeguards No evidence of NW program Fatwa by Supreme Leader forbidding NW Inalienable right to Fuel Cycle Need for Independence? Japan:  Japan Owns about 45 tons of reactor-grade Plutonium Only about 10% of this is stored in Japan The designated purpose of this material is for use in Mixed Oxide Fuel (MOX) and breeder reactors. These uses have been delayed or cancelled. Reactor-grade Plutonium is useable in NW North Korea (DPRK):  North Korea (DPRK) 1985 DPRK joins NPT 1991 US withdraws NW from South Korea 1992 DPRK concludes Safeguards Agreement with IAEA but IAEA detected 90g diversion of plutonium 1993 DPRK announces intent to withdraw from NPT. IAEA demands more access to Yongbyon reactor. Many US – DPRK diplomatic contacts North Korea (DPRK) cont’d:  North Korea (DPRK) cont’d October, 1994: US and DPRK sign “Agreed Framework” DPRK stop reprocessing Korean Energy Development Organization (KEDO) to build two LWR’s and to supply fuel oil Many follow-on diplomatic moves North Korea (DPRK) cont’d:  North Korea (DPRK) cont’d 1998 South Korea “Sunshine Policy” 1998- 2000 Extensive diplomatic bilateral contacts, including visit by Secretary of State Albright to Pyongyang North Korea (DPRK) cont’d:  North Korea (DPRK) cont’d 2001 Secretary of State Powell declares to “pick up where President Clinton left off,” but retracts and diplomacy turns hostile. 2002 President Bush includes DPRK in “axis of evil” in State of Union speech.

Secretary of State James Kelly visits Pyongyang. US claims that DPRK admitted to Kelly that it had an HEU enrichment program. DPRK denies this, stating they only claimed a right to enrichment. Translation problem? DPRK enrichment program has disappeared from media. North Korea (DPRK) cont’d:  North Korea (DPRK) cont’d November 2002 KEDO suspends fuel oil shipments in response to US enrichment claims. IAEA challenges enrichment. December 2002 DPRK restarts reactor, removes IAEA seals, expels inspectors. North Korea (DPRK) cont’d:  North Korea (DPRK) cont’d January 2003 DPRK withdraws from NPT 2003 DPRK tells US and China it has NW Six Nation Talks; US refuses bilateral talks 2006 DPRK tests NW The CTBT and Nonproliferation:  The CTBT and Nonproliferation Long History: 1958 initiatives Partial Test ban: 1963 LTBT Reality versus Symbolism CTBT cited in all NPT Review Conferences Reality Cost to National Security low Technical benefit to Nonproliferation low Cost-Benefit Ratio is Quotient of two small quantities The CTBT has been signed by most nations but is not in force. The US Administration opposes ratification. The CTBT Monitoring system is in place and is supported by the US. The CTBT Matrix:  The CTBT Matrix Options NNWS Countries No CTBT CTBT Complied with by all countries CTBT all countries cheat to extent possible without detection Highly Developed Developing Least Developed What type of NW can each country build? Conclusion: US interest served better with CTBT, obeyed or not, than without CTBT. (NAS, 2002) Remedies to Proliferation:  Remedies to Proliferation What won’t work in the long run Discriminatory “Coalition of the Willing” Proliferation Security Initiative (PSI) Selective enforcement Divide world into fissile materials suppliers and receivers Military pre-emption of nascent nuclear facilities (Israel v. OSIRAK, 1981) Remedies to Proliferation (cont’d):  Remedies to Proliferation (cont’d) What may work International fuel supply and return of spent fuel to international control Strengthen IAEA; make Additional Protocol mandatory Broaden negative and positive security assurances Make withdrawal from NPT subject to U.N. Security Council Action Positive & Negative Security Assurances:  Positive & Negative Security Assurances NWS give assurances to + Come to the assistance of a NNWS threatened or attacked with NW – Not to attack a NNWS with NW unless the NNWS is allied with a NWS Remedies to Proliferation (cont’d):  Remedies to Proliferation (cont’d) What will help Universal No First Use acceptance by all NWS Drastic reduction of Nuclear Weapons stockpiles by formal Treaty by NWS Lessened reliance on military options in international relations US leadership in all of the above …because… US leadership:  US leadership US is strongest military power measured by conventional military strength and economic power and “You cannot preach temperance from a bar stool.” …Rep. Ed Markey, 2006 And “Never negotiate with the United States unless you have a nuclear weapon.” …Indian Deputy Minister of Defense Ultimately:  Ultimately Nuclear Nonproliferation Demands that every Nation concludes that its security and Well-Being are served better without nuclear weapons than with them.
