Information at Nuclear Facilities

 8th NUMUG Meeting

St. Charles, ILMay 9, 2002

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-3.11Attributes

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?

No longer active per ANS Standards rules Technically outdated Emphasizes siting, not operation of nuclear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-3.11Design 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.

ANSI/ANS-3.11REGULATORY IMPLICATIONS

NRC RESPONSE (7/94)

“…we are not aware of any safety issues which would suggest that a revision of this Regulatory Guide (1.23) is in order.”

“…NRC approval is not needed for ANS to revise the subject standard.”

“We cannot make a commitment at this time to endorse the revised ANSI/ANS-2.5 (ANSI/ANS-3.11) without a compelling safety argument.”

“…the NRC will determine how to support your activity.”

ANSI/ANS-3.11REGULATORY IMPLICATIONS

NRC’S CURRENT POSITION ON METEOROLOGY (05/02)

SAFETY GUIDE 23 (AKA, R.G. 1.23) IS STILL IN EFFECT.

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.
