ASME NQA.TR-2020 pdf free download.Evolution of Quality Assurance Principles and Requirements in the U.S. Nuclear Industry.
This Section describes the evolution of nuclear quality assurance from early quality control and inspection requirements for AEC nuclear weapons production and naval reactors programs; to the more comprehensive quality assurance program requirements for nuclear weapons production and AEC/DOE reactor development and technology activities; to the series of DOE quality assurance directives.
1.2 AEC WEAPON QUALITY POLICY, QC-1 AND NAP-24
AEC quality management policy for nuclear weapons complex activities was first documented In the AECs Santa Fe Operations Office (SF0) Weapon Quality Policy, QC-1. Issued in April 1954, QC-l predated MILQ-9858A. 1 the widely used DOD specification for military quality assurance programs that was issued in 1959.
The Initial edition ofQC-1 included the followingquality control and inspection principals and requirements:
(a) specification and drawing control
(b) quality control procedures
(c) control of inspection gauging and test equipment
(d) production tooling accuracy
(e) in-process inspection and records
(U control of special processes
(g) SF0/DOE source inspection
(h) raw material and deviation control
QC- 1 prescribed general principles and practices for AEC-SFO acceptance inspection of nuclear weapons systems and auxiliary equipment from prime contractors. It required weapons program prime contractors to establish and implement quality control systems to ensure, among other things, that nuclear weapons materials met minimum quality standards. SF0 expected these principles and requirements to be applied also to ordnance plants operated by DOD on the behalf of SF0 and to arsenals that performed work for the SF0 under agreements with DOD.
In 1982, the DOE Assistant Secretary for Military Applications defined,2 and In 1989 redeflned in greater detail, the quality assurance policy for the DOE nuclear weapons complex. This policy required the execution and mainte• nance of procedures that
— provided control, through plans and actions, over activities affecting quality to an extent consistent with defined programmatic or organizational objectives
— had objective, measurable means to ensure their ellectiveness, which were required to be used by management for regular assessments
— emphasized continuous improvement in all activities, Including both support and operational organizations
— applied appropriate elements of recognized standards
QC-1 was revised numerous times from its initial issue in 1954 through 2004. In 2013. QC-1, Revision 10, was replaced by National Nuclear Security Administration (NNSA) Policy Letter NAP-24. QC-1 and NAP-24A addressed changes and additional DOE weapon quality policy and quality assurance requirements. Thus, for example, QC-1, Revision 6, issued in 1992, added quality system requirements for training of manufacturing, inspection, and test personnel, and for quality improvement, error prevention versus detection, and nonconformance costs.
The highly classified nature of most DOE Defense Program (DP) weapons production activities governed by QC-1 led to some external criticism that DP lacked a viable quality assurance effort that complied with DOE quality assurance directives. DP quality management policy in the 1980s exempted the DOE nuclear weapons program from complying with DOE quality assurance orders on the basis of equivalency.ASME NQA.TR pdf download.
