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.
