Title: Technical Specification Surveillance Interval Extension of Digital Equipment in Nuclear Power Plants: Review and Research

Abstract

The nuclear industry has been slow to incorporate digital technology into nuclear plant designs for several reasons, including: • The high cost of design change modifications to implement them, versus simply replacing them with like for like technology when the components fail. • Digital technology qualification issues, particularly in safety related applications that are susceptible to software common cause failure. This is a concern both for current operating plants as well as new builds. • General familiarity and comfort with the existing analog technology on the part of the nuclear plant engineering staff, in spite of the superior performance and reduced maintenance costs of the digital replacements. At the same time, the nuclear industry is under significant cost pressure in the electric marketplace due to the abundance of natural gas generation and renewables. The industry would benefit by investment in new technologies that could lower future operating costs while addressing obsolescence and reliability issues of the current analog technologies. However, the industry has been unable to formulate the business cases to take advantage of these labor savings and production reliability improvements.
