  1. The Role of Meteorology in the Nuclear Power Industry Presented at the 15th Annual RETS-REMP Workshop June 27-29, 2005 Wilmington, NC Theodore A. Messier, Meteorologist Framatome ANP 978-568-2378 Theodore.Messier@Framatome-ANP.com

  2. What role does meteorology play in our industry? • Site acceptability studies • Doses to the public from routine effluent releases • Emergency response • Control Room habitability (radiological and • chemical) • Design engineering (statistics)

  3. What regulatory guidance is available? • NRC Safety Guide 23/Regulatory Guide 1.23 • Regulatory Guide 1.21 • Regulatory Guide 1.78 • Regulatory Guide 1.111 • Regulatory Guide 1.145 • Regulatory Guide 1.183 • Regulatory Guide 1.194 • ANSI/ANS-3.11-2000 • EPA QA Handbook

  4. What regulatory guidance is available? • NRC Safety Guide 23/Regulatory Guide 1.23 • Regulatory Guide 1.21 • Regulatory Guide 1.78 • Regulatory Guide 1.111 • Regulatory Guide 1.145 • Regulatory Guide 1.183 • Regulatory Guide 1.194 • ANSI/ANS-3.11-2000 • EPA QA Handbook

  5. What regulatory guidance is available? • NRC Safety Guide 23/Regulatory Guide 1.23 • Regulatory Guide 1.21 • Regulatory Guide 1.78 • Regulatory Guide 1.111 • Regulatory Guide 1.145 • Regulatory Guide 1.183 • Regulatory Guide 1.194 • ANSI/ANS-3.11-2000 • EPA QA Handbook

  6. What issues have been seen recently? • No ownership of the program • Conflicting procedural requirements • Loss of experienced personnel • Data manipulation errors • Outdated/unsupported software

  7. Solutions • Insure that someone owns the meteorological monitoring system • If in doubt about your program, have an outside expert perform an audit • Capture the experience of personnel that are leaving the organization • Vigorously check meteorological data manipulations, unit conversions, and format changes • Insure that your people have the right tools

  8. Introducing MetData • FANP’s response to the issues we’ve seen recently • PC/Windows based software • Intended to help both meteorologists and non-meteorologists in maintaining high quality meteorological data • Data storage, checking, editing, JFD tables, atmospheric dispersion factors, data reformatting all in one application

  9. MetData • Data checking module produces a report with an explanation of why the data were considered suspect and suggestions of how to check data validity • Data may be flagged by the user as “BAD” with the click of the mouse • Data editing report shows changes on a line-by-line basis

  10. MetData • Helps you meet regulatory requirements by producing annual meteorological data summaries in the form of joint frequency distribution tables of wind speed and direction as a function of atmospheric stability • Produces atmospheric dispersion factors for routine effluent releases • These factors can be used to rank locations in the annual Land Use Census • Reformats your meteorological data for use with the NRC computer code ARCON96
