UNITED STATES NUCLEAR REGULATORY COMMISSION ADVISORY COMMITTEE ON REACTOR SAFEGUARDS WASHINGTON, D. C. 20555 May 16, 1983 Mr. William J. Dircks Executive Director for Operations U. s. Nuclear Regulatory Co~nission Washington, DC 20555 De a r Mr. Di r ck s :
Subject:
ACRS ACTION ON PROPOSED REGULATO~Y GUIDE ON INSTRUMENT SENSING LINES {TASK NO. IC 126-5)
During its 277th meeting, May 12-14, 1983, the Advisory Committee on Reactor Safeguards concurred in the regulatory position of the proposed Regulatory Guide on Instrument Sensing Lines {Task No. IC 126-5), dated November 8, 1982.
We note that the provisions of this Guide and the Standard referenced in it are not to be backfitted to those nuclear power plants now operat-ing or under construction.
We are concerned that there may be instrument lines in operating plants in which inappropriate combinations of transducers are connected to common instrument 1 ines.
We recommend that the operating plants be examined to verify that failure of such lines would not cause unaccept-able consequences.
Sincerely, Jesse C. Ebersole Acting Chairman 3100
