Global Trends in Nuclear Power

• 162/437 NPPs have been in operation for more than 30 years and 22 for

more than 40 years (as of 09/2013)

• 56 years in operation - the oldest

IAEA

Why has long term operation of NPPs become so

favourable in NPPs worldwide?

Important factors supporting LTO:

1.Safety Safety enhanced

2.Performance High capacity factors reached

3.Production O&M cost reduced

4.Environment Emission free electricity

5.Public Opinion Public confidence and support ???

Challenges of safe long term operation

1. Unclear national energy strategy

a. Difficult to decide on investment for LTO

b. Lack of rules for LTO preparation

2. Routine operation of old units

a. Difficult to acquire young engineers

b. The best personnel attracted to operation of new modern plants

3. Post-Fukushima situation

a. Change of political and public acceptance

b. New safety requirements

IAEA Conference on Operational Safety

Experience and Performance – June 2010

• MAIN RECOMMENDATIONS

• MS with support from international organizations like IAEA need to

proactively work on sharing experience obtained in AM of currently

operated reactors and assessment of safe LTO of older NPP.

• Need for sound knowledge of the actual state of the plant and verification

that adequate safety margins will be maintained. In support of this a

practical guide to assist MS in implementing, maintaining and improving

effective AMPs for different reactor design is requested by MS and IAEA

should develop an international harmonized document (IGALL).

• Importance of nuclear share in energy mix is requiring continued safe

operation of older existing reactors while construction of new capacities

is ongoing. Under these circumstances, the role of independent safety

reviews is becoming more and more important. Utilities, vendors and

regulators should exchange experience, using opportunities to broaden

their knowledge and take benefit from IAEA Safety Review Services for

LTO and AM.

IAEA

Objectives of IGALL Programme

• Establishment of a state-of-the-art IGALL report, as guidance on

recommendable ageing management programmes.

• Basis for implementation of recommendable AMPs for NPPs with diverse

technologies: PWR, BWR, WWER, CANDU, PHWR, etc.

• The IGALL report would be updated and upgraded periodically at least

every 5 years.

• Perceived as a “living document”.

• Fundamental document in supporting a systematic approach to managing

ageing of a variety of structures or components as described in the Safety

Guide NS-G-2.12.

IAEA

Some of recently identified issues:

• There are no specific regulatory requirements for long-

term operation (LTO).

• Authorized LTO and PLIM policy documents on plant

and company level are not available. The draft

documents currently in use, are not yet authorized

A - Organization and functions, current licensing basis,

configuration/ modification management (section 3.1);

36

IAEA

Some of most frequently identified issues:

• Existing plant methodology refers only to regulatory

requirements which are to be used in the wider sense

of QA and not specifically for SSCs selection with

respect of LTO.

• In a few plants scoping of SSCs for LTO is not

complete.

B - Scoping and screening and plant programmes relevant

to LTO (section 3.2);

37

IAEA

Some of most frequently identified issues:

• Investigation and correction of equipment degradation

is initiated reactively following failure of the equipment.

• Databases to support LTO activities are separated,

scattered, do not have integration ability.

• Maintenance effectiveness reviews, including trending

of basic performance indicators, is not in place.

• The various maintenance activities (ISI, Functional

Testing, Maintenance) are carried out by different

groups. Consistent goals and objectives for all

maintenance activities related to LTO are missing.

C, D, E - Ageing management review, review of AMPs and

revalidation of TLAAs for mechanical, electrical and I&C

components and civil structures (section 3.3);

38

IAEA

Some of most frequently identified issues:

• Insufficient staffing of the LTO project with competent

resources;

• Systematic approach for Competence and Knowledge

management is not implemented for long term

operation of the plant.

F - Human resources, competence and knowledge

management for LTO (section 3.4);
