ListServer

• 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.

ANSI/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.

12
ANSI/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.

13
ANSI/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.

14
ANSI/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).

15
Survey 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.

16
Survey of Monitoring Systems

• Survey Topic Areas

• 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

Survey of Monitoring Systems(Participants)
19
Survey of Monitoring Systems

• Use of survey results

• 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.

20
Survey 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?

21
Survey 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.

22
Survey 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.

23
Survey of Monitoring Systems
What methodology should be used for future
surveys?

• Hardcopy.
• E-mail.
• Website.
