NE Series NP-T-3.21 “Procurement Engineering & Supply Chain Guidelines in

Support of Operation & Maintenance of Nuclear Facilities”

– Typical procurement processes;

– Considerations of special

importance and lessons

learned;

– Procurement of services;

– Procurement of software and

items containing software;

– Counterfeit, fraudulent and

substandard items;

– Proactive methods for new

NPPs to avoid procurement

related issues

Managing counterfeit and fraudulent

items in the nuclear industry

Legitimate (left) and counterfeit (right) valves.

The "L" logo on the counterfeit valve appears to have been added via welding

(instead of cast into the valve body) and "cleaned up" with grinding.

Examples

Outage Optimization - Challenge

• How to manage & control

contractors efficiently ?

• How to control design change &

replacement effectively ?

• How to improve work control & FME

effectively ?

• How to assess the effectiveness of

outage performance ?

Cable Aging of Samples for CRP

Benchmark on Condition Monitoring

• Thermal

• Radiation

• Thermal-Radiation

Irradiation Cell (AECL) Irradiation Thermobox (UJV)

Thermal (AMS and others)

Two sizes of cable sample in the benchmarking tests. • Diameter of 15 mm for all of the mechanical/chemical test • Diameter of 10 mm for all of the electrical tests.

*The Habia cable was thermally aged at 190°C which caused permanent maximum insulation degradation at the

first aged condition. No trending was possible for the electrical cable samples.

Very Useful Good correlation with ageing. Low laboratories variability.

Useful Reasonable correlation with ageing. Some laboratories

variability but consistent trends.

Potentially Useful Moderate correlation with ageing. Large variability but method

shows potential for improvement.

Not Useful No correlation with ageing.

No Data or Not Applicable No data available on this programme or test method not

applicable for that material (e.g. electrical test for jacket

polymers).

Potentially Useful (Limited) Moderate correlation with radiation ageing only.
