5. International Atomic Energy Agency
Created in 1957, based in Vienna, Austria.
Autonomous Intergovernmental Organization.
Reports to UN General Assembly and UN Security Council.
Currently 159 Member States (2013)

6. IAEA cont.
Composed of a General Conference, Board of Governors, and Director General.
General Conference comprises of all member states and is the policy making body of the IAEA.
Board of Governors examines and makes recommendations to the General Conf. regarding accounts, and budget of IAEA.

7. IAEA cont.
Objectives:
Providing safe, secure, and peaceful uses of nuclear technology and science to nations.
Ensuring that any nuclear activities that the IAEA are involved with are not being used for any military agenda.

8. IAEA cont. Made up of five departments:
Nuclear Science and Applications
Nuclear Energy
Nuclear safety and Security
Technical Cooperation
Safeguards

9. IAEA cont.
Nuclear Science and Applications: Helps member countries in the use of atomic and nuclear radiation in agriculture, medical programs, industrial applications…etc.
Nuclear Energy: Promotes the efficient and safe application of nuclear power for peaceful means; mostly power generation.

10. IAEA cont.
Nuclear Safety and Security: Establish measures for the protection of people and the environment from radiation, and to develop programs for the response to nuclear accidents.
Technical Cooperation: Helps nations improve their scientific and technological abilities for peaceful uses of nuclear technology.

11. IAEA cont.
Safeguards: Carries out its responsibilities as the world’s inspector in an effort to stop the spread of nuclear weapons.
IAEA is the only international Agency with the responsibility of inspecting nuclear facilities across the world, to insure the signed agreements are being followed.

12. IAEA cont.
It creates policies to ensure that weapons materials do not become available the non-nuclear weapon states or terrorist organizations.
This information is distributed to member states in reports known as Information Circulars.

13. Non-Proliferation Treaty
Completed in 1968.
Original five nuclear weapon states realized that if more countries develop nuclear weapon, then the risk of nuclear accidents will increase.
The effort to limit NWS resulted in the NPT.

14. NPT cont. 190 States have currently signed.
India, Pakistan, and Israel never signed.
Three Important declarations of the NPT:
Nuclear weapon states promise not to provide weapons materials and technology to anyone else and to commit to disarmament.

15. NPT cont.
2. States with nuclear technology promise to help others without it, with the idea that every state should reap the benefits of nuclear energy. 3. The Treaty recognizes the inalienable right of every state to utilize nuclear energy for peaceful purposes.

16. NPT cont.
Conferences were held in both 1995 and 2010 to extend and reaffirm the NPT.

17. Information Circulars
Informational reports that IAEA distributed regarding agreements made by member states.
854 have been released.
Most recent have been about a response from Iran about the UN’s efforts and concerns about nonproliferation in the state.

18. INFCIRC cont. Three most important INFCIRC are:
INFCIRC/66 (1968): The Agency’s Safeguards System- Lists the duties and obligations of the IAEA, and the procedures and principles of implementing safeguards.

19. INFCIRC cont.
2. INFCIRC/153 (1972): The Structure and Content of Agreements between the Agency and States Required in Connection with the Treaty on the Non- Proliferation of Nuclear Weapons- Agreements should include a guarantee by the state to accept safeguards set by the Treaty and the IAEA.

20. INFCIRC cont.
3. INFCIRC/540 (1997): Model Protocol Additional to the Agreement(s) between State(s) and the IAEA for the Application of Safeguards- States must adhere to: 1. Freely give all information regarding a State’s Fuel Cycle.

21. INFCIRC cont.
2. Provide information on the manufacture and export of devices using nuclear technologies and inspection mechanisms for manufacturing and import locations of such devices.

22. INFCIRC cont.
3. Allow, after short notice, IAEA inspections of all buildings on a nuclear site. 4. Collection of environmental samples at the IAEA’s discretion.

23. Safeguards
Safeguards: Policies, procedures, and controls set up by the IAEA to achieve nonproliferation.
Safeguard efforts are centered on international treaties and the activities of the IAEA.

24. Deterrence of such diversion because of the risk of detection.
Objectives:
Timely detection of diversion of nuclear materials for peaceful activities to the manufacture of nuclear explosives.
Detection of diversion of nuclear materials or information from one state to another or to a non-state group for making nuclear explosives.
Deterrence of such diversion because of the risk of detection.

25. Safeguards cont.
Completing these objectives are based on the verification of the national system of accountancy and control of nuclear materials.
Verification is done by IAEA inspections, surveillance, and material accountability.

26. Safeguards cont.
Following the NPT, nuclear weapon states follow IAEA Safeguards voluntarily:
US, UK, France, India: All Civil Facilities
Russia: Not all, yet
China: All imported nuclear facilities
Pakistan: Civilian reactors under restricted agreement
North Korea, Israel: No civilian nuclear power

28. Agreements: treaties or agreements between the IAEA and a State for the application of Safeguards.
INFCIRC/66-type safeguards agreement — specifies the nuclear material, non-nuclear material, facilities and or equipment to be safeguarded.

29. Voluntary offer agreement (VOA) — between IAEA and a NWS to answer concerns that Safeguards could lead to commercial disadvantages.
Comprehensive safeguards agreement (CSA) — an agreement that applies safeguards on all nuclear material in all nuclear activities in a State.

30. Compliance with Safeguards
Every state with a signed agreement with the IAEA must prove that it complies to the agreement.
Use of Nuclear Material accountability.
Upon inspection, the State must demonstrate and prove that the documented material mass at each nuclear facility match the real inventory.

31. The difference between the documented and real inventory is called material unaccounted for (MUF).
MUF= (PB+X-Y)-PE
PB= beginning physical inventory
X= increases to inventory
Y=decreases to inventory
PE= ending physical inventory

33. Example
An Uranium enrichment facility currently holds 600kg of U, a shipment of 25kg of U comes in the same day as 3kg of U is being shipped out to a national lab. IAEA inspectors come the next day to find 623kg of U on site. What is the MUF and is it acceptable?

34. Noncompliance with Safeguards
“Noncompliance” is found throughout the founding articles of the IAEA.
However, not well defined.
Up to Board of Governors to decide.

35. Events that may constitute Noncompliance:
MUF is high or unexplained: ( mass measured< documented inventory)
Nuclear material or nuclear activity has not been declared.
Use of nuclear material is not clearly civil, if there is suspicion that it may be use for military purposes.
Military grade nuclear material or information related to the military use of nuclear material has been given to a third party.

36. In the course of a Noncompliance inquiry the following questions are asked:
Does evidence of falsehoods and concealment exist? Thus indicating the actions were deliberate.
What material is involved?
(natural U, thorium, fissile material…etc)
What are the activities involved? Can they lead to enrichment and weapons grade material?
Where is the material?

37. To declare Noncompliance, according to INFCIRC/153:
Nuclear material or activity has not been declared or that is has been removed from Safeguards.
The failure is considered significant.
The purpose of the nuclear material or activity is military based or uncertain.
To remedy Noncompliance, the State comply to the steps in INFCIRC/153 & 540.

38. Strategic Nuclear Materials
Materials safeguards are place on:
Thorium
Uranium
Plutonium
“Not all isotopes are created equally”
IAEA classifies materials as:
Direct Use Materials
Special Fissionable Materials
Indirect Use Materials

39. Direct Use Material
Can be use to create nuclear explosive devises without further enrichment or transmutation
Pu containing < 80% Pu-238
Highly enriched Uranium
U-233
MOX Fuel
UNF (used nuclear fuel)

40. Indirect use Material:
All material except Direct use Material
Natural & low enriched Uranium
Depleted Uranium
Thorium
Special Fissionable Material (Special Nuclear Material):
Pu-239, U-233, Uranium enriched in U-233,235
Other fissionable material determined by BOG
Doesn’t include source material (U or Th in any physical or chemical form or ore contain at least .05% of either

41. Effective Kilogram (ekg):
Max quantity of nuclear materials in “location outside facility”
LOF: any installation or location where nuclear materials used are < 1 ekg
ekg: determined by:
Pu weight (kg)
U enriched > 1%: [weight (kg)]*[ enrichment 2 ]
.5%< U enriched < 1%: [weight (kg)]*[.0001]
U enriched < .5% or Th: [weight (kg)*[.00005]

42. Significant Quantity:
Amount of nuclear material that could possibly be used to manufacture a nuclear explosive devise.
Takes into account unavoidable losses due to conversion and manufacturing process.
Not Critical Mass
INFCIRC/66:
IAEA demands info regarding materials used in fission reactors:
Nuclear grade Graphite, heavy water, deuterium, zirconium and zirconium alloys

44. Nuclear Fuel Cycle and Proliferation
1970s U.S. conducted study called: the Nonproliferation Alternate Systems Assessment Program (NASAP).
NASAP determined:
No fuel cycle is 100% proliferation resistant
Once-through fuel cycle is the most .proliferation resistant due to the fact that the weapons grade material is never separated during the cycle.

45. Detection of Nuclear Materials
Cases where detection may be required:
Border crossing screening ( required of cargo containers and carriers).
Screening of materials in transit.
Searching for and seizing materials at suspicious locations.
After a radiological weapon has been detonated.

46. Methods for detection:
Chemistry (radiochemistry or mass spectrometry) or radiation based ( detecting ionizing radiation).
Destructive or Nondestructive.
Active or Passive.

47. Active Detection Method:
“Interrogation Method”
External radiation (neutron or gamma) irradiates a sample which produces measurable radiations.
Radiations produced result from the fission of fissile material.
Neutron Sources:
14 MeV neutrons from a neutron generator.
Spontaneous fission of Cf-252 producing fast neutrons.

48. Active Detection Method cont.:
Photons > 6 MeV are used to initiate photofission (gamma, fission) reaction.
Produced as Bremsstrahlung using an electron accelerator.
Fissile material is indicated by fission neutrons and gammas.

49. Passive detection Methods:
Neutrons from spontaneous fission from (alpha, neutron) reactions in the sample.
X-rays emitted by decaying fissile isotopes.
All isotopes under safeguards undergo spontaneous fission as a mode of decay.
He-3 counter is used to detect the neutrons.

51. Passive detection Methods cont.:
Safeguarded isotopes also emit X-rays.
X-rays are detected by high purity Germanium crystals.
Passive methods can experience difficulty detecting both neutrons and X-rays if the material is shielded
Due to the low amount of neutron emission and soft X-rays.

53. Proliferation Resistance and Physical Protection
Proliferation Resistance (PR): Characteristics of a nuclear energy system that prevents the production or diversion of nuclear materials or technology by the State in order to acquire any nuclear explosive devices.

54. Physical Protection (PP):
Physical Protection (PP): Characteristics of a nuclear energy system that impedes the theft of materials or the sabotage of facilities and transportation by rouge groups.
International effort led by GEN-IV International Forum (GIF) to create PR& PP for nuclear materials in Gen-IV reactors.

55. Intrinsic and Extrinsic measures are used to improve PR.
Intrinsic PR features as defined by the IAEA “ are features that result from the technical design of nuclear energy systems, including those that facilitate the implementation of extrinsic methods.

56. Extrinsic methods supports PR by use of:
Extrinsic methods are features that result from decisions and policies made by the host State related to nuclear energy.
Extrinsic methods supports PR by use of:
NPT
agreements between the State and the IAEA
Verification processes
AEA Inspections

57. PR threats: Conceal diversion/acquisition of nuclear weapon materials.
Conceal production of nuclear weapon materials.
Misuse of declared facilities or materials.
Production of materials in undeclared hidden facilities.

58. PP threats:
Theft of nuclear material or information that can be used for creating nuclear explosive devices.
Sabotage of facilities and or transportation materials by rouge groups.

59. Barriers against theft depend on the material:
Material characteristics
Location of materials.
GIF are currently researching and developing designs for Gen-IV reactors that maximize their PR capabilities.
Safeguards by design.
