  1. A Training Simulator
    For operators and engineers training in reactor theory, transient phenomena, and diagnostic skills. A comprehensive training lesson plan from basic principles to symptom-oriented emergency diagnosis can be developed in conjunction with the software.
  2. Generate emergency drill scenarios and conduct actual exercises. Data at a selected time interval can be prepared and handed out to drill teams for an undisclosed event. Data on core damage, radiological release, and offsite dose projection support comprehensive exercises.
  3. Parametric/Scoping Study
    For system modifications and licensing support, development of emergency procedures, responding to regulatory inquiries about system performance, equipment sizing, operator actions, etc., repetitive runs can be conducted with immediate turnaround for answering "what if" questions.
  4. Probabilistic Risk Assessment (PRA)
    To predict consequences of selected event branches leading to core melt and/or containment failure and their contributions to overall plant risk. Application in Individual Plant Examination (IPE) front-end prediction of core uncovery.


Technical Information

Hardware & Software Requirements

Minimum system requirements are a Pentium or any compatible processor and SVGA graphics. The operating system should be at least Windows 95 or NT 4.0 with MS Office Suite installed. Simulation speed is adjustable from real-time to faster than real-time, dependent on processor speed. For a 500 MHz processor, the maximum speed is about 16 times faster than real-time.

Services provided by MST

Installation and on-site training can be arranged, if necessary. Maintenance and technical support are provided free of charge for the first year upon delivery. Extended technical service is available upon request.

These downloads are not play-back-only demos but actually functional software that can conduct extensive simulations with interactive control.

The primary display mimics the nuclear steam supply system (NSSS) and the containment system of a PWR with two or more inverted U-bend steam generator loops. The generic model can be modified to be "plant specific" for any Westinghouse, C-E, Framatome, or KWU design. A plant specific version may either use the lumped loop model or each loop be modelled individually.

The display also represents the controllable system as small panels with the important equipment shown as icons (i.e., pumps, valves, heat exchangers). Control rod position and motion are displayed by the motion of simulated control rods. If there is a break in the NSSS, it will be shown dynamically at the break location with the flow rate digitally displayed.

On the right-hand side panels of the mimic, there are control panels for the reactor, steam generators and turbine, pressurizer, etc. Panels for the High Pressure Injection System, Accumulators, Residual Heat Removal System (RHR), Reactor Building Spray, Vent, and Fan Coolers are at the left side. At the bottom of the mimic, there are panels for Reactor Protection System (RPS), Safety Feature Actuation System (SFAS), and P-T diagram showing the primary coolant's saturation margin.
