Sellafield substantiates first SMART annunciator in compliance with requirements of the UK NII

With the increasing reliance on “SMART” instruments in safety systems, the problem of substantiating the software in these instruments has been a concern of the NII for a number of years.

The EMPHASIS tool was developed to assist the nuclear site operators to achieve a common level of substantiation whilst eliminating duplication of effort. The SIL1 certified Omni16C alarm annunciator has been substantiated by EMPHASIS for use in the UK nuclear industry.
