NucSIG Event – 9 th June 2010 Submarine 1 st 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 – 9 th June 2010 High precision items of equipment such as Submarine 1 st 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.

NucSIG Event – 9 th June 2010 Even basic items can at times present a challenge! Example one being: A Weld Insert

NucSIG Event – 9 th June 2010 What is a Weld Insert?

NucSIG Event – 9 th June 2010 A Formed Insert - to form the root of a weld

NucSIG Event – 9 th June 2010

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

NucSIG Event – 9 th June 2010 Second example is something as basic as:- Locking Wire

NucSIG Event – 9 th June 2010

Where is it used? – Inside the Steam Generator Purpose - to wirelock the fasteners which hold Chevrons and Driers etc

NucSIG Event – 9 th June 2010 Associated Problem –Material Shortcoming –Material Analysis –Documentation Checks –Supply Chain –Audit and Findings. –Additional Issues

NucSIG Event – 9 th 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 – 9 th 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 – 9 th June 2010 But what if the certification reads?

NucSIG Event – 9 th June 2010 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!
