2About NUMUG
- Nuclear Utility Meteorological Data Users Group
(NUMUG) - Mission and Objective is to provide a forum to
address problems and exchange ideas for those
collecting and utilizing meteorological data at
nuclear facilities. - Membership is open to any individual interested
in pursuing the mission and objectives of the
group.
3NUMUG Organization
- NUMUG has a written charter.
- NUMUG is managed by the Steering Committee.
- The Steering Committee consists of five members,
with at least three members representing U.S.
electric utilities.

6ListServer
- Sponsored by Lawrence-Livermore Lab (ListServer
established by Frank Gouveia). - Provides a forum to address problems and exchange
ideas for those collecting and utilizing
meteorological data at nuclear facilities. - A variety of topics are covered, including
meteorological instrumentation, data-collection
techniques, quality assurance, emergency
preparedness, regulations and standards, and
meeting announcements.

11ANSI/ANS-3.11
- Initiated by NUMUG with support from the
Department of Energy (DOE) Meteorological
Coordinating Council (DMCC). - Began as a review of ANSI/ANS-2.5 -1984,
Standard for Determining Meteorological
Information at Nuclear Power Sites. - The working group consisted of approximately 30
individuals from across the whole range of
organizations involved in meteorological data
collection at nuclear facilities.
12ANSI/ANS-3.11
- Changes in ANS-3.11
- Add operational data applications (not just
siting). - Apply to both private and public (DOE DOD)
entities. - Consider the entire nuclear plant life cycle.
- Address multiple monitoring locations for
modeling applications. - Include state-of-the-art meteorological
monitoring equipment. - Issued as ANSI/ANS-3.11-2000, Determining
Meteorological Information at Nuclear Facilities.
13ANSI/ANS-3.11
- During the 2003 review, the Working Group
determined that the standard needed updating. - New reference standards
- Advances in instrumentation
- Advances in data management
- Advances in program management
- Issued as ANSI/ANS-3.11-2005, Determining
Meteorological Information at Nuclear Facilities.
14ANSI/ANS-3.11
- During 2008, the Working Group will reevaluate
ANSI/ANS-3.11-2005 and determine action to be
taken prior to the standards sunset in 2010. - Reaffirm
- Sunset
- Update
- New working group members are welcome.
- The working group needs new chairmen.
- (Thanks to Stan Marsh and Carl Mazzola).
15Survey of Monitoring Systems
- One of NUMUG's first activities was to compile a
data base of meteorological monitoring programs
to help focus NUMUG's efforts. The original
survey was conducted during 1992 and the results
were presented in 1993. - The second edition of the survey was conducted
during 1997-1998 with results presented in 1999.
16Survey of Monitoring Systems
- Identification
- Unit Information
- Site Characteristics
- Meteorological Tower Information
- Variables Monitored
- Meteorological Instrumentation
- Recording and Auxiliary Equipment
- Off-Site Data Sources
- Maintenance and Calibration
- Data Processing and Archiving
- Administration

18Survey of Monitoring Systems(Participants)
19Survey of Monitoring Systems
- Design a new system or upgrade an existing
system. - Determine the best equipment for a particular
site. - Compare experiences with other operators
concerning particular equipment. - Compare monitoring programs for similar sites.
20Survey of Monitoring Systems
- Is survey information used as intended?
- Who uses the survey information?
- Is the survey information useful?
- What other applications can take advantage of the
survey information? - What deficiencies are there in the survey
information?
21Survey of Monitoring Systems
Is there a need to update the survey?
- Some information is out-of-date.
- Facilities have changed operational status.
- Equipment changes have been made.
- New facilities are planned.
22Survey of Monitoring Systems
What should be the nature of future surveys?
- Non-comprehensive (large surveys may discourage
participation). - Multiple small surveys.
- Targeted to specific types of facilities or
specific users.
23Survey of Monitoring Systems
What methodology should be used for future
surveys?
- Hardcopy.
- E-mail.
- Website.
