Download Quality Assurance and QA Monitoring

12.1 Quality Assurance and QA Monitoring
All aspects of this project, design, procurement, fabrication, construction, construction
management and assembly activities will be periodically reviewed with regard of Quality
Assurance issues from conceptual design through to completion.
The requirements of a Quality Assurance Plan can be applied to various systems, components,
structures, and related services based on the complexity and safety aspects of the particular
item or related services. To provide a consistent basis for identifying the specific quality
requirements to the system, structure, component or related service, a set of definitions is
outlined below identifying three levels of control to meet the MICE QA. These are as follows:
Level I: Those systems, components, structures and materials whose design problems are so
unique as to require design verification or whose failure or malfunction would:
Jeopardize the facility and surrounding area personnel safety.
Reduce safe emergency experiment facility shutdown capability.
Jeopardize the RAL/ISIS beam operation.
Such systems would cover, for example, the hydrogen system and vacuum chambers which
are considered as pressure vessels and will be covered by a full safety assessment and review.
Level I Systems:
Liquid Hydrogen Systems
System Pressure-relief Protection Systems
Personnel Protection and Interlock Systems
Plant Protection Systems
High Voltage Systems
Level II: - Systems, components, structures or materials associated with the MICE experiment
whose failure would:
Render the MICE inoperable for excessive period of time.
Cause a subsequent hazard in some other (MICE) system or damage other critical MICE
equipment.
Require long lead times for replacement items or repairs to MICE
Cause loss of full performance design capability of MICE.
Cause unacceptable delays in construction or start-up schedules due to a nonconformance to
specifications upon delivery.
Such systems are the major components of MICE. An example is needed: failure of a vacuum
window for example? Level II systems will be subject to an internal MICE design and safety
review.
Level II Systems:
RF Cavity and Coupling Coil Module
RF Power System
Absorber and Focus Coil Modules
Structural Support components
Vacuum System
Cryogenic liquefied gases, Receiving, Storage, Handling
201 MHz

Data Acquisition
Level III: - Items not covered at level I or II.
These items will be contained within level II items and be scrutinized during the level II
review process.
Level III items:
Vacuum pumps?
Off the shelf items?
This procedure was prepared to ensure that the execution of the equipment supply from its
procurement through to the manufacturing and final delivery can be traced with convincing
evidence that each operation is done to the satisfaction of meeting the standard of quality that
is fit for the nature of the project. This QA procedure is intended to be simple to implement
without loosing sight of its quality issues.
In addition to the above detail of scrutiny, the procedures should allow the project to
scrutinise (through review) the design, cost, schedule, material and procurement plans at
appropriate stages to ensure correct adherence to codes and project standards.
