The nuclear industry and the U.S. Nuclear Regulatory Commission (USNRC) have been working for several years on the development of an adequate process to guide the replacement of aging analog monitoring and control instrumentation in nuclear power plants with modern digital instrumentation without introducing off-setting safety problems. This book identifies criteria for the USNRC's review and acceptance of digital applications in nuclear power plants. It focuses on eight areas: software quality assurance, common-mode software failure potential, systems aspects of digital instrumentation and control technology, human factors and human-machine interfaces, safety and reliability assessment methods, dedication of commercial off-the-shelf hardware and software, the case-by-case licensing process, and the adequacy of technical infrastructure.Their software quality assurance programs were generally modeled after IEEE 7- 4.3.2a1993 and IEC 880 and had been audited and approved by USNRC staff. ... of nuclear utilities engaged in digital Iaamp;C upgrades: Baltimore Gas and Electric Company, Public Service Electric and Gas ... Manual inspections of test results were necessary because of timing problems between the PPS and the test driver.
