The Modular Accident Analysis Program (MAAP) has been developed and maintained by Fauske & Associates since the beginning of the code in 1981. In addition to developing and testing this integral plant model, FAI has provided support on the use of MAAP for a wide range of plant evaluations. Examples of this support include:

• Design basis evaluations.
• Level 1 and Level 2 success criteria for Probabilistic Risk Assessments (PRAs).
• Evaluations of time intervals available for operator response.
• Radiological source term assessments.
• LERF quantification.
• Integration of MAAP or selected MAAP models into full scope control room simulators.
• Plant evaluations for all operating modes.
• Accident management guidance evaluations.
