NUMUG Survey (Second Edition) 2 of 68

The Nuclear Utility Meteorological Data UsersGroup (NUMUG) was founded to provide a forum

to address problems and exchange ideas amongthose collecting and utilizing meteorological data

at nuclear power plants and facilities.

One of NUMUG's first activities was to compile adata base of meteorological monitoring programs

to help focus NUMUG's efforts. The originalsurvey was conducted during 1992 and the

results were presented in 1993.


The second edition of the NUMUG survey wasdeveloped by streamlining the original survey

and adding some new items.

The second edition of the survey was conductedduring 1997-1998 with results presented in 1999.

The second edition of the survey should beconsidered a supplement to the original survey.


Reasons for Updated Survey

• Facilities had made numerous changes. • Address maintenance and calibration, data

processing and archiving, and general administrative issues.

• Include Department of Energy (DOE) sites.


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

Analog Recorders

• Strip-chart recorders output a continuous pen trace of directly-received electronic signal

• Hybrid recorders receive digital signal, perform internal processing, and print output as a series of closely spaced marks.

• Both types of recorders can include more that one data trace on a single chart.

Digital Recorders• Usually receive numerous input data values for a

specified time period (generally 10 or 15 minutes and hourly).

• Perform calculations.• Output a single value that is representative of the

time period.• Output data are normally stored in electronic

format, may be printed locally, and transmitted to other sites.

Data Recovery Problems

CAUTION

Information concerning problems should be interpreted with care because of the relatively small total number of problems

actually listed.

A relatively minor problem at one or a few facilities included in the survey may look much more significant than is really

the case for the nuclear industry as a whole.
