ELISA-2

 

ELISA-2 is a software package developed for the radiological Evaluation of LIcensing and Severe Accidents at light-water nuclear power plants. It is based on the classical and alternative-source-term methodologies.

 

ALLEGRA

 

ALLEGRA is a software package that analyzes radioactive decay products and gamma spectra as a function of decay time, based on up to 7-member decay chains and the ORIGEN-2 data libraries.

 

DIDOS-5E

 

DIDOS-5E is a point-kernel shielding software package for the computation of direct-shine radiation doses from gamma rays emanating from a self-attenuating cylindrical source surrounded by a number of containers, and shielded by semi-infinite slabs. The software was designed for carefree applications and requires just a few lines of input. The available geometries can handle the majority of gamma shielding problems typically addressed by the nuclear power industry.

 

AEOLUS-3

 

AEOLUS-3 is a software package for the determination of atmospheric dispersion and deposition of nuclear power plant effluents during continuous, intermittent and accident conditions, in open-terrain sites, coastal sites and deep-river valleys.

For further details on the capabilities of each software click on the respective titles.  You will also find a list of key features and basic features providing general background information to help emphasize the benefits of the Alternative-Source-Term methodology and the need of ELISA-2.  Supporting figures are provided where indicated.  A documentation package list is also included for each code.

Please note that the listed software complement each other. For instance, the atmospheric dispersion and deposition factors for input into ELISA-2 can be prepared by AEOLUS-3, and the time-dependent gamma spectra produced by either ELISA-2 or ALLEGRA can be used directly by DIDOS-5E.
