6. 6 Terms and Definitions Quality:
The condition achieved (or existing) when an item, service or process meets or exceeds the users’ requirements or expectations (Source:DOE)
Quality assurance:
All those planned and systematic actions necessary to provide adequate confidence that a structure, system, or component will perform satisfactorily in service.
(Source: 10 CFR 50 Appendix B)
All those actions that provide confidence that quality is achieved (or exists) (Source:ASME NQA-1)
7. 7 Terms and Definitions QAP - An overall plan, program or management system established to:
Define quality policies, purpose, objectives, requirements, standards, practices and procedures
Scope applicable items and activities
Assign organizational responsibilities and authorities for management, achievement and assurance of quality
Designate need for training and qualification of personnel
Provide for performance, assessment and continual improvement of work processes
(Source: ASME NQA-1, DOE)
8. 8 NQA Paradigm Shift Ineffective Concept
Quality is “inspected into” an item. Present NQA-1 Culture
Quality is achieved by people possessing the competence, skills, knowledge, experience, training, resources and work ethic and motivation to do the job right.
9. 9 NQA Paradigm Shift Ineffective Concepts
NQA-1 was written by and for QA professionals
NQA applied only to safety structures, systems and components
NQA program required strict compliance with inflexible requirements and procedures
Present NQA-1 Culture
NQA-1 is written by and for managers, performers and verifiers.
NQA-1 requires a quality management system that applies to safe and reliable operation across the nuclear facility.
NQA-1 program applies a sensible graded approach that is both compliance and performance oriented.
10. 10 NQA Paradigm Shift Ineffective Concept
Quality professionals are primarily responsible for planning, documenting and implementing the organization’s quality assurance program (quality management system)
Present NQA-1 Culture
Persons who manage, perform and verify work all contribute to planning, documenting and implementing an integrated, cost effective and efficient quality management system to produce a quality product
11. 11 NQA Paradigm Shift Ineffective Concept
A QAP generates excessive amounts of paper. Present NQA-1 Culture
QAP documentation is readily available to provide sufficient objective evidence and a defensible record that NQA requirements and commitments have been met.
12. 12 NQA Program Lesson “No quality assurance program is self-executing. Thus, irrespective of how comprehensive it may appear on paper, the program will be essentially without value unless it is timely, improved and properly implemented.”
(Source: ASLB at Consumer Power Midland Station public licensing hearings, March 1973)
13. 13 NQA Program Lesson “Top-down management commitment to quality is a primary project objective.
Top management must understand the magnitude, complexity and difficulties in designing and constructing nuclear power plants compared to conventional steam plants, and the importance of applying exacting engineering and quality standards.
Prior nuclear facility design and construction experience of key project personnel is essential.”
(Source NRC NUREG-1055)
“Improving Quality and the Assurance of Quality in the Design and Construction of Nuclear Power Plants”
14. 14 NQA Program Lesson “There is a level of change actions – technical, regulatory and procedural – beyond which any project management structure can no longer effectively implement its quality assurance program.”
(Source: NRC NUREG-1055)
15. 15 NQA Program Lesson The QAP is implemented as an integral part of a comprehensive management system.
The QAP supports prompt detection, communication and correction of quality problems in design, effective management system oversight of the design process, and the ability to control plant configuration and manage change.
