History and Mandate

• 1953 “Atoms for Peace” address by US President Eisenhower to UN General Assembly;

• First General Conference held in 1956; Agency officially established in 1957;

• Today has 168 Member States (welcome Turkmenistan!; note there are

193 MS’s in the UN) , – 30 of which operate commercial

NPPs;

– 55 with research reactors;

– Rest use nuclear technology for other purposes (e.g. medical, scientific) and/or plan NPPs.

– Fuel channels (PHWR)

• Includes aspects related to organization and project structures.

Procurement Engineering and Supply Chain Guidelines

(new NP-T-3.21)

• New guide to be published 2016 (approved and currently in layout process);

• Covers information on: – Typical procurement processes;

– Considerations of special importance and lessons learned;

– Procurement of services;

– Procurement of software;

– Counterfeit and fraudulent items;

– Proactive methods for new NPPs (importance of ensuring complete turnover of plant data).

Industrial Safety Guidelines for

Nuclear Facilities • New NE Series document being

co-sponsored by the

International Labour

Organization.

• An update of IAEA guidance on

topic that hadn’t been addressed

since 1990’s (TECDOC-535).

• Industrial Safety is an integral

part of OSART missions.

• Going for internal IAEA

publication approvals this

month. Formal issuance in 2017. Bruce Power approach to overall

nuclear safety

CONSTRUCTION READINESS

REVIEW

Construction Readiness Review Guidelines

• Focus is on a specific NPP

construction project (new

build or refurbishment), not

the overall programme.

• Must have design chosen

and construction

preparations underway at a

very detailed level.

• Guidelines finalized and

published. Service available

now!

Risk Assessment Methodologies (from Risk Informed Approach for Nuclear Security Measures, Security Series No. 24)

• Risk registry: Mapping of identified scenarios onto a matrix of likelihood and consequence scales for comparative visualization of risks. May be qualitative or semi-quantitative.

• Probabilistic risk assessment: Scenario based approach that combines principal elements or ‘steps’ leading to an event with consequences (usually shown graphically as an event/fault tree) and estimating the ultimate consequences for each of the defined scenarios. It obtains the overall likelihoods of scenarios. similar to a probabilistic safety assessment.

• Both approaches depend upon models to represent possible events and upon judgements by subject matter experts to define likelihoods.

NUCLEAR CONTRACTING

TOOLKIT PROJECT

Nuclear Contracting Toolkit

• Project designed to produce a web-based ‘toolkit’ of easy to use model forms/spreadsheets to assist in various aspects of the bidding and contracting process for new builds and major projects.

• Includes some details on risk management;

• Beta version posted to public web site; https://www.iaea.org/NuclearPower/Infrastructure/NuclearContractingToolkit/index.html

• Formal launch to coincide with NP-T-3.21 issuance later in summer/fall of 2016.
