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


• 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


• What is a Weld Insert?


• A Formed Insert - to form the root of a weld


• Associated Problem

– Welding Issue– Material Analysis– Documentation Checks– Wider concern and further checks– Supply Chain– Audit and Findings


• Second example is something as basic as:-

Locking Wire


• Where is it used?

– Inside the Steam Generator

Purpose - to wirelock the fasteners which hold Chevrons and Driers etc


• Associated Problem

– Material Shortcoming

– Material Analysis

– Documentation Checks

– Supply Chain

– Audit and Findings.

– Additional Issues


• 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?


• 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


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!
