If you are interested in participating in the following standards, complete and submit the Standards Volunteer Form.

ANS-2.3, Estimating Tornado, Hurricane, and Extreme Straight Line Wind Characteristics at Nuclear Facility Sites

Scope: The purpose of this standard is to specify guidelines to determine the wind velocity, atmospheric pressure change, missile type, size and velocity that result from tornadoes, hurricanes and other extreme winds to be used in nuclear facility design. The standard does not treat forces that result from these natural events.

ANS-2.15, Criteria for Modeling and Calculating Atmospheric Dispersion of Routine Radiological Releases from Nuclear Facilities

Scope: This standard establishes criteria for use of meteorological data collected at nuclear facilities to evaluate the atmospheric effects on routine radioactive releases, inclusive of dilution, dispersion, plume rise, plume meander, aerodynamic effects of buildings, dry, deposition, and wet deposition (e.g., precipitation scavenging).

ANS-2.16, Criteria for Modeling Design-Basis Accidental Releases from Nuclear Facilities

Scope: This standard established criteria for use of meteorological data collected at nuclear facilities to evaluate the atmospheric effects on accidental radioactive and chemical releases, inclusive on dilution, dispersion, plume rise, plume meander, aerodynamic effects of buildings, dry deposition, and wet deposition (e.g., precipitation scavenging). These criteria may also be useful in Department of Homeland Security (DHS) consequence assessments.

ANS-2.21, Criteria for Assessing Atmospheric Effects on the Ultimate Heat Sink

Scope: This standard establishes criteria for use of meteorological data collected at nuclear facilities to evaluate the atmospheric effects from meteorological parameters (e.g., dry-bulb temperature/wet-bulb temperature differential, precipitation, wind speed, short wave radiation, incoming solar (short wave) radiation, surface water temperature, and atmospheric pressure) on ultimate heat sinks.

ANS-2.31, Standard for Estimating Extreme Precipitation at Nuclear Facility Sites

Scope: This standard addresses extreme natural site hazards associated with precipitation (rain, snow, ice and their combination) which are applicable to structures, systems and components in nuclear safety-related facilities with probabilities of exceedence or return periods consistent with extreme design basis category wind, flood and earthquake phenomena (i.e. ANS 2.1, ANS 2.3, ANS 2.8, ANS 2.14, ANS 2.26, ANS 2.27 and ANS 2.29).

ANS-3.8.10, Criteria for Modeling Real-time Accidental Release Consequences at Nuclear Facilities

Scope: This standard establishes criteria for use of meteorological data collected at nuclear facilities or nearby stations to evaluate in real time the atmospheric effects on all anticipated accidental radioactive and hazardous chemical releases during emergencies, inclusive of atmospheric transport and dispersion
