NucSIG Event – 9th June 2010
• Submarine 1st Level Quality Assurance
PURPOSE
To ensure that submarines are operated and maintained to the correct
Standard and to the correct Specifications so that they are capable of
achieving their design performance throughout their operational life.
SCOPE
Applicable in 3 main systems areas:
Submarine Safety
Reactor Safety
Personnel Safety
NucSIG Event – 9th June 2010
• High precision items of equipment such as
Submarine 1st Level Items:
– PUMPS
– VALVES
– ACTUATORS etc, etc.
Are subjected to a high level of control throughout the design,
manufacture, assembly, operation and overhaul phases. It
becomes a real challenge to ensure the intended operation of
the item meets the customers exacting requirements.

• Even basic items can at times present a challenge!
Example one being: A Weld Insert

NucSIG Event – 9th June 2010
• How might you procure steel tubing at short notice?
Use a detailed QA Statement of Requirements?
Use an ISO certificated steel stockist?
Use a major UK stockist of steels, alloys & plastics?
Use a local stockist we have approved?
Use a stockist with a proven track record?
NucSIG Event – 9th June 2010
• Our Purchase Order Specification demanded
material certification for:
Chemical, Mechanical, Heat Treatment, Ultrasonic, Surface
Finish, Pressure & Dimensional
• Demonstrates design intent maintained
• Safety Case reliability targets not undermined
NucSIG Event – 9th June 2010
But what if the certification reads?

•
All examples are basic items
All examples involved additional testing
Some involved concession action
One supplier no longer used
Other given additional supply conditions
Each example incurred extra costs
• No budget for additional supply chain assurance
Especially Overseas!
