Study Notes
NUCE 304: Evaluative Methods for Nuclear Non-proliferation and Security
- Course title: NUCE 304: Evaluative Methods for Nuclear Non-proliferation and Security
- Lecture topic: Nuclear Safeguards (Introduction)
- Instructor: Dr. Ahmed Alkaabi
Introduction and Basics of International Safeguards
- This section introduces the fundamental concepts of international safeguards.
“3S” Integration - Safeguards
- Nuclear Safety: Focuses on operating conditions, accident prevention and mitigation, protecting workers, public, and the environment from radiological hazards.
- Nuclear Safeguards: Aims to prevent and detect the theft or diversion of special nuclear material from civilian facilities, utilizing material control and accountancy.
- Nuclear Security: Emphasizes preventing and responding to sabotage, unauthorized access, or other malicious acts involving nuclear material, radioactive substances, or associated facilities.
- "3S" Culture: Highlights the integration of safety, safeguards, and security to create a holistic approach for safe and reliable operation of electric energy facilities.
“3S” Integration - Safeguards (Elements)
- Emphasizes that several elements—training, engineering & technical services, operations, safety, security, emergency response, administrative and maintenance—work together to maintain safe, secure, reliable, and economical electric energy provision.
“3S” Integration - Safeguards (Diagram)
- Shows the integration of safety, security, and safeguards in a nuclear facility (various components).
Definition: Nuclear Safeguards
- Nuclear Safeguards are a set of measures implemented to verify that states adhere to international (Treaty) obligations, not using nuclear materials for nuclear explosives.
Nuclear Safeguards Measures
- Nuclear Material Accountancy
- Containment and Surveillance
- Design Verification
- Reports and Inspections
Why Safeguards?
- The presentation begins with a historical overview of the first nuclear weapons project and the use of nuclear weapons to demonstrate:
- The power of nuclear weapons.
- The importance of avoiding further use.
- The importance of safeguarding nuclear materials.
The Manhattan Project
- Started in 1942
- Secret project
- Involved 120,000 people
- Cost $2 billion
Trinity Test
- The first nuclear explosion.
- Location: Jornada del Muerto, Alamogordo, New Mexico.
- Date: July 16, 1945
"Little Boy" and "Fat Man"
- Nuclear bombs detonated in Hiroshima and Nagasaki, respectively.
- Dates: Hiroshima - August 6, 1945; Nagasaki - August 9, 1945
- Yields: Hiroshima ~20,000 tons TNT; Nagasaki ~21,000 tons TNT
Effects of Nuclear Weapons
- Blast (40-60% of total energy).
- Thermal radiation (30-50% of total energy).
- Ionizing radiation (5% of total energy).
- Residual radiation (5-10% of total energy).
- Physical damage and human suffering.
Peaceful Use of Nuclear Energy
- Production of electricity, medical diagnostics, medical treatments, food irradiation, oil well logging, and non-destructive assay of materials.
The Mandate: IAEA Statute (1957)
- Establishes and administers safeguards to ensure that special and other materials aren't used for any military purpose.
International Safeguards Regime
- International safeguards are designed to promote peaceful use of nuclear energy and ensure fissile materials are used only for peaceful purposes.
Why Control Nuclear Materials?
- Building blocks for nuclear weapons.
What are IAEA Safeguards?
- IAEA independently verifies states' declarations regarding nuclear material and activities.
- Safeguards ensure safeguarded items aren't used for military purposes.
- Measures are implemented under various agreements and protocols.
Components of the IAEA Safeguards System
- Nuclear Material Accountancy
- Containment and Surveillance
- Design Verification
- Reports
- Inspections
Objectives of IAEA Safeguards
- Timely detection of diversion of nuclear materials for weapons.
- Detection of undeclared nuclear material and activities.
Safeguards Agreements and Applications
- Agreements between IAEA and states/groups of states.
- Requirements fulfilled for projects or supply agreements.
- Implementing bilateral or multilateral agreements (treaties).
- At the request of a state to any of that state's nuclear activities.
- Various types of agreements may exist.
Types of Safeguards Agreements
- INFCIRC/66-type (based on INFCIRC/66): nuclear and non-nuclear materials, facilities, or equipment.
- INFCIRC/153-type: Comprehensive safeguards agreement, Voluntary Offer Agreement, Small Quantity Protocol.
Additional Protocol Coverage
- Safeguards coverage expansion
- Covers various areas of nuclear facilities
Examples of Reductions in Safeguards Measures under IS
- Irradiated fuel timelines extended from 3 to 12 months.
- Fresh MOX fuel in LWRS timelines extended from 1 to 3 months.
- One-level lower methodology for the verification of indirect use of materials.
State-Level SG Approach
- Designed for each state with tailored safeguards approaches based on specific facilities, taking into account IAEA state evaluation, state nuclear fuel cycle, interaction between facilities, and other state-specific features.
Non-Compliance
- Violation of safeguards agreements by a state may include diversion of nuclear materials, failure to declare materials, obstruction of IAEA activities, and interference with the operation of equipment.
Types of Non-Compliance: Diversion
- Undeclared removal of declared nuclear material from safeguarded facilities.
- Use of a safeguarded facility for introduction, production, or processing of undeclared nuclear material.
- Undeclared production of plutonium in a reactor.
Types of Non-Compliance: Misuse
- Use of non-nuclear material and equipment under safeguarded facilities for an unauthorized purpose.
Exemption from IAEA Safeguards
- States can request exemptions for nuclear material for certain intended uses or limitations.
- Gram amounts as sensing components.
- Plutonium with an isotopic concentration exceeding 80%.
- Re-application of safeguards required in certain cases.
Safeguards Approaches (Flow Chart)
- Explains a sequential approach to implementing and maintaining safeguards programs:
- Beginning with acquiring facility information and signing an agreement.
- Establishes the goals of safeguards to be implemented.
- Identifying diversion/acquisition paths and analyzing various approaches to managing these paths.
Nuclear Materials – A Few Definitions
- Source material: Depleted uranium, natural uranium, thorium. Ore and ore residue not included.
- Fissionable material: Isotopes/mixtures capable of nuclear fission.
- Special fissionable material: 239Pu, 233U, uranium enriched in isotopes 235 or 233.
Material Types
- Categories of nuclear materials, based on the element and enrichment level (for uranium). Includes Plutonium, Uranium, U-233, and Thorium. Specific types of Uranium are also identified, like Depleted, Natural, Low Enriched, and Highly Enriched.
Direct and Indirect Use Material
- Nuclear material is categorized into direct use and indirect use.
- Direct use involves materials for use in nuclear weapons.
- Indirect use involves the other varieties of nuclear materials.
Significant Quantity (SQ)
- Defined approximate quantities of nuclear material for which the possibility of manufacturing a nuclear explosive device cannot be excluded
- Includes accounts of unavoidable losses in the conversion/manufacturing processes.
