Summary
SNAP/RADTRAD has two parts. The RADTRAD Analytical Code (AC) itself, is a licensing analysis code used to show compliance with nuclear plant siting criteria, and is which is distributed by RAMP. SNAP consists of a suite of integrated applications designed to simplify the process of performing engineering analysis, the SNAP application package (including RADTRAD Plugin) is distributed by Information Systems Laboratory, Inc.
RADionuclide, Transport, Removal, and Dose Estimation (RADTRAD)
The RADionuclide, Transport, Removal, and Dose Estimation (RADTRAD) code is a licensing analysis code used to show compliance with nuclear plant siting criteria for the site boundary radiation doses at the Exclusion Area Boundary (EAB) and the Low Population Zone (LPZ) and to assess the occupational radiation doses in the control room (CR) and /or Emergency Offsite Facility for various loss-of-coolant accidents (LOCA) and non-LOCA design basis accidents (DBAs). RADTRAD uses a combination of tables and numerical models of source term reduction phenomena to determine the time-dependent dose at the CR, EAB and LPZ for given DBA scenarios.
Symbolic Nuclear Analysis Package (SNAP)
The Symbolic Nuclear Analysis Package (SNAP) consists of a suite of integrated applications designed to simplify the process of performing engineering analysis. SNAP is built on the Common Application Framework for Engineering Analysis (CAFEAN) which provides a highly flexible framework for creating and editing input for engineering analysis codes as well as extensive functionality for submitting, monitoring, and interacting with the codes. SNAP is developed by Information Systems Laboratories (ISL), Inc. and is sponsored by the NRC. It provides the RADionuclide, Transport, Removal, and Dose Estimation (RADTRAD) user with a graphical user interface with pre– and post–processor capabilities allowing users to develop RADTRAD input decks.
