ANSI/ANS-3.11 Determining Meteorological Information at Nuclear Facilities :  ANSI/ANS-3.11 Determining Meteorological Information at Nuclear Facilities Stanley L. Marsh, CCM, Southern California Edison     8th NUMUG Meeting St. Charles, IL May 9, 2002 ANSI/ANS-3.11 :  ANSI/ANS-3.11 Purpose Report on ANSI/ANS-3.11, a new Standard for Determining Meteorological Information at Nuclear Facilities. Explore nuclear industry position on approaching NRC for their endorsement of ANSI/ANS-3.11. Initiate steps to reaffirm, revise, or modify ANSI/ANS-3.11. ANSI/ANS-3.11 Attributes:  ANSI/ANS-3.11 Attributes Reflects the current operational and regulatory climate by incorporating state-of-the-art data acquisition, processing, and recording technology. Applicable to all nuclear facilities nationwide, civilian nuclear power industry and Federal government. Replaces ANSI/ANS-2.5; clarifies existing issues and provides additional guidance without imposing new requirements. Represents a technically sound, state-of-the-art standard without consideration of regulatory forcing functions. Why Was ANSI/ANS-2.5 Replaced? :  Why Was ANSI/ANS-2.5 Replaced? No longer active per ANS Standards rules Technically outdated Emphasizes siting, not operation of nuclear facilities Does not reflect current in situ meteorological instrumentation standards Does not consider remote sensing technology Does not reflect state-of-the-art data acquisition, processing, and archiving technology Inconsistent with USEPA and ASTM guidance Addresses only civilian nuclear power plants and not all non-reactor nuclear facilities Does not address meteorological program life cycle considerations Does not fully address complex terrain siting and operational issues Inconsistent with NEXRAD, ASOS, EPA, and ASTM guidance ANSI/ANS-3.11 Design Criteria :  ANSI/ANS-3.11 Design Criteria Replace ANSI/ANS-2.5, not just revise it. Applicable to both civilian nuclear power industry and Federal Gov’t nuclear facilities. Applicable to meteorological monitoring supporting siting, licensing, operation, emergency response, decontamination, and decommissioning of nuclear facilities. Reside in ANS-3.0, Operations. Rely on existing, technically sound, meteorological guidance. Develop new guidance only where necessary. Stand alone, technically sound document.

PROPOSED REV. 1, AND 2nd PROPOSED REV. 1 TO R.G. 1.23 WERE NEVER ADOPTED. AT PRESENT, THERE IS NO EFFORT, ONGOING OR PLANNED WITHIN NRC, FOR AN UPDATE OR REVISION. NRC IS WAITING FOR AN INDUSTRY TRADE GROUP (e.g. NUMUG) TO TAKE THE INITIATIVE TO GET ANSI/ANS-3.11 RECOGNIZED.
