28 September 2007 Mr. Alexander Marion, Executive Director Nuclear Operations & Engineering Nuclear Energy Institute 1776 I Street, NW, Suite 400 Washington, DC 20006-3708
Dear Mr. Marion:
The purpose of this letter is to provide you with the U.S. Nuclear Regulatory Commissions (NRCs) Digital Instrumentation and Control (I&C) Interim Staff Guidance (ISG) addressing the application of digital technology to operating and new nuclear power reactors and fuel cycle facilities.
Consistent with the Project Plan dated July 12, 2007 (ML071900253), the digital I&C Task Working Groups (TWGs) have been continuously working with their industry counterparts to develop ISGs to refine, enhance, and clarify existing guidance. The approved ISGs will help guide NRCs reviewers in their reviews of digital I&C technology, and will be in effect until they are further refined and incorporated, as appropriate, into revisions of applicable regulatory documents.
Enclosed for your information are copies of the finalized digital I&C ISGs to date:
DI&C-ISG-02, Diversity and Defense-in-Depth (ML072540118)
DI&C-ISG-04, Highly-Integrated Control Room - Digital Communication Systems (ML072540138)
DI&C-ISG-05, Highly-Integrated Control Room - Human Factors (ML072540140)
The above ISGs do not convey a change in the NRCs regulations or how they are to be interpreted. Since the ISGs provide documentation of the existing acceptance review criteria associated with existing regulations, the NRC staff did not perform a backfit evaluation as no backfits are imposed by the enclosed ISGs.
If you have any questions, please contact me at 301-415-1274.
Sincerely, John A. Grobe, Associate Director for Engineering and Safety Systems Office of Nuclear Reactor Regulation
