ENTECH Engineering is a consulting company providing technical support and computer software to the nuclear power industry in the areas of radiological engineering, and atmospheric dispersion of radioactive effluents. ENTECH's software codes are thoroughly documented and validated, and among the very best in the industry.

One of ENTECH's primary objectives is to make its software available to the electric utilities for enhancement of their in-house capabilities. A brief description of each follows: 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 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 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 DIDOS 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 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.
