MST has successfully developed PCTRAN for KSNP1000 and APR1400. By arrangement with our distributor in Korea - FNC Technology, the APR1400 severe accident and RadPuff model is licensed to Korea Institute of Nuclear Safety as a research project. The OPR model is licensed to Jeju University and YeoungNam University for education. Free Download
The first APR1400 will be operational in Shin-Kori 3 and 4 soon in Korea. An APR1400 is also slated for construction in the UAE.
Note following the lessons learnt from the Fukushima event, passive hydrogen recombiners and ignitors have been incorporated and in-vessel retentrion strategy is investigated.

The Fort Calhoun Station of Omaha Public Power District and Comanche Peak Plant of Luminant Power have upgraded their PCTRAN applications with spent fuel pool and area dose projection features. The severe accident scenarios now cover hydrogen burn, directing LOCA sump water into reactor cavity to cool vessel failure debris, outside containment LOCA ("V" event), etc.

Nuclear Desalination Plant
Micro-simulation Technology developed a simulator for a 200MW low temperature heating reactor NHR designed by Tsinghua University of China for desalination. The nuclear plant is coupled with a MED-TVC (multiple effect distillation – thermal vapor compression) unit to generate distilled water. Point kinetics is used to solve core power evolution from cold to critical and power conditions. The steam generated by the nuclear plant is directed to four parallel units of MED-TVC. Using fourteen vacuum chambers (effects) to evaporate the steam with a compressor, this MED-TVC process reaches a gain output ratio (GOR or distilled water production / nuclear steam rate) of over 15. The fresh water production is 120,000 tons per day. We have also completed a simulator for another type of desalination device - VTE or vertical tube evaporation - that reaches a higher production of 160,000 tons of pure water per day.
The simulator facilitates training and design for plants such as these that are optimized for regions with low fresh water supplies. It also serves as a useful tool in studies of economic feasibility and cost. Free Downloads
Can a NPP become a WMD?
Can a nuclear power plant become a weapon of mass destruction by accident or sabotage? Well, the highly radioactive core and spent fuel inventory is hazardous if released to the environment on a large scale. The possibility cannot be ruled out so that the US Army Combating WMD Agency (USACWMD) has acquired two of our basic simulator modules - one PWR and one BWR to train its staff. A training course will cover all possible accidents and their impact to public safety.
Exactly for the same idea the Hong Kong government and the Defense Laboratories DSO of Singapore are prepared for possible radiological events originated either inside or beyond their territories. Training sessions were conducted in late July of 2012. We have also licensed to State Radiation Protection Agencies of New Jersey and Pennsylvania. So look out DHS and states' colleagues, you'll find the right stuff right here.

New online data acquisition and consequence projection system assures no mega-disasters ever again
With the aftermath of the 1979 Three Mile Island event, every plant in the world followed the US’s lead of installing a so-called Safety Parameter Display System (SPDS), which transmits key plant operations data to offsite support centers for emergency support and response. So in principle a large pool of superior technical resources is available around the clock to mitigate an event’s severity. Yet this did not prevent the tsunami-caused damage to the Fukushima units from evolving into a major disaster. The reason is that despite awareness of the plant’s condition, the support staff did not have a robust means for projecting its consequences nor come up with plausible solutions.
Over the sixty years development of the world nuclear power industry, there have been no shortage of sophisticated computer analysis tools and replica training simulators capable of transient simulation. However, during the first weeks or so of the Fukushima accident, none were capable of predicting or reproducing the four Daiichi units’ outcome that could lead to meaningful mitigation measures. With the exception of Micro-Simulation Technology’s PCTRAN BWR3 and 4 models, within days we were able to provide explanations for the events that transpired and post the results online. Our analysis turned out to be the only thing credible. It is highly consistent with what was announced by the IAEA and Japanese authorities (see later details below).
Owing to the PCTRAN model’s relative simplicity yet high degree of fidelity in modeling each and every specific NPP, the technology is mature enough to construct an “Online NPP Incident Projection System”.
By using a selected subset of real-time plant data, anything exceeding a pre-determined 2nd level such as “Alert” in the US four Emergency Activation Level (EAL) system will be automatically downloaded onto a dedicated PC and warning is sent to mobilize the supporting analyst team. The team will perform faster-than-real-time projection of the event using various mitigating routes. The best solution will be recommended to the control room crew. Should there be core-melt or dose release, the source term and dose distribution will be immediately reported to higher authorities.
Using existing Internet-based SPDS, MST is working with a few NPPs to build the first online pilot systems. Since each key component is already handy, within months it will be ready for testing.
