Nuclear Fuel Cycle Simulation System

The Nuclear Fuel Cycle Simulation System (NFCSS), formerly known as VISTA, is a scenario-based computer model for the estimation of fuel cycle material, service requirements and actinide arisings.

The NFCSS is a computer simulation system which uses simplified approaches to calculate the fuel cycle requirements.

These simplified approaches enable the code to estimate the long-term fuel cycle requirements for both open and closed fuel cycle strategies.

The NFCSS web site provides a detailed description of the simulation system, an example scenario with results, and a simple calculation tool which can be used to calculate annual material flow in a selected nuclear fuel cycle option.

The web site also provides access to the full version of the code through a special authorization.
