3 THE IAEA 3

4 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. 4

5 Major work areas Nuclear energy Nuclear safety and security Safeguards Nuclear sciences and applications Technical Cooperation 5

6 IAEA SAFETY STANDARDS

7 IAEA Safety Standard Document Hierarchy Target Audience : Regulators (and by extension owner-operators) Safety Fundamentals: Present objectives, concepts, principles of protection and safety. Basis for Safety Requirements. Safety Requirements: Establish the requirements that must be met to ensure the protection of people and the environment. Governed by the Safety Fundamentals. Safety Guides: Provide recommendations and guidance on how to comply with the Safety Requirements. 7

10 Selected requirements Documented MS Processes to be defined Continual improvement processes / corrective action programmes Promote a strong safety culture, including with contractors Safety shall be paramount Requirements can be graded based on risk, novelty of work and safety consequence Need adequate resources and trained staff Defined process needed for managing contractors and temporary workers (including providing oversight) Contractors to demonstrate subcontractors have knowledge of safety requirements specific to the subcontract prior to award of subcontracts.

11 Selected requirements (cont. d) Inspection, testing, verification & validation requirements and acceptance criteria to be specified Configuration management is critical Plant modifications, products, and documents and records to be controlled System needed to ensure legal and regulatory requirements are translated into designs, procedures, etc.

12 Selected requirements (cont. d) Regulatory oversight of construction to verify licensee compliance; Licensee retains responsibility for all activities that could affect the safety of the installation, irrespective of the location where the activities are carried out; Licensee should appoint a construction manager from its own organization; Construction org. should have contingency plans for critical activities (loss of utilities, disruption of concrete batching, etc.). 12

13 Selected requirements (cont. d) Detailed recommendations surrounding: planning and scheduling; procurement specifications; prerequisites to starting work; environmental conditions; cleanliness and foreign material control; receipt, transport and storage of material; verification of work; impacts on adjacent installations; on-site manufacturing.

14 NUCLEAR ENERGY SERIES CONSTRUCTION RELATED PUBLICATIONS

15 IAEA Nuclear Energy Series Target Audience : owner-operators, governments, NEPIOs Complementary objectives, guides, and reports supporting safety and other goals (e.g. good practices, plant economics, etc.) Nuclear Energy Basic Principles General Nuclear Power Nuclear Fuel Cycle Radioactive Waste Management & Decommissioning Management Systems Human Resources Nuclear Infrastructure and Planning Economics Energy System Analysis Knowledge Management Technology Development Design & Construction of NPPs Operation of NPPs Non-Electrical Applications Research Reactors Resources Fuel Engineering and Performance Spent Fuel Management & Reprocessing Fuel Cycles Research Reactors Fuel Cycle Radioactive Waste Management Decommissioning of Nuclear Facilities Site Remediation

16 Project Management in NPP Construction Construction management Preparatory Phase Construction phase (after concrete pouring) Commissioning phase Main issues and lessons learned Selection of local suppliers; Bulk material management; Worker turnover; Construction equipment; Massive movements of people and material; Public perception; Construction phase closure activities; Country specific lessons learned

17 Construction Technologies for New NPPs Goal: Achieving an optimum construction schedule for future NPP construction projects. Content: Comprehensive descriptions of all construction methods Advantages / disadvantages Best practices Lessons learned

18 Heavy Component Replacement in NPPs Experience and guidelines for replacement of heavy components in NPPs such as: Steam generators Reactor vessel heads Reactor vessel internals Reactor coolant lines Pressurizers Fuel channels (PHWR) Includes aspects related to organization and project structures.

19 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).

20 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 Bruce Power approach to overall nuclear safety

21 CONSTRUCTION READINESS REVIEW 21

22 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!

27 Risk management: A tool for improving NPP performance IAEA- TECDOC-1209 (2001)

28 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.

29 NUCLEAR CONTRACTING TOOLKIT PROJECT

30 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; ngtoolkit/index.html Formal launch to coincide with NP-T-3.21 issuance later in summer/fall of 2016.

32 MEETING OBJECTIVES

33 Meeting Objectives Share experiences related to project risk management for nuclear construction and refurbishment projects; Share experiences related to the development and use of different tools and techniques for nuclear project risk management; Create a list of risk methodologies for nuclear construction projects; Explore Member States future needs with respect to nuclear construction risk management (e.g. new publication, web site, workshops, training, expert missions etc.). 33
