The Riskspectrum History

RiskSpectrum is a trademark for risk- and reliability software. The owner of this trademark, Relcon Scandpower AB, have today developed 6 software packages in the RiskSpectrum software family.

Relcon Scandpower is dedicated to long term software development, especially in the field of nuclear PSA. The major strategic goal is to provide RiskSpectrum licensees with the next generation software tools ensuring a sustainable solution for their continued and uninterrupted PSA activities. It is also important, for the software's continued existence, that it stays competitive and remains the preferred choice of risk assessment engineers worldwide.

In 2007 a new 32-bit version of RiskSpectrum PSA will be released. So far more than 30000 person-hours have been spent developing this update. The new version is developed using the latest development environment from Microsoft, .NET. This makes it possible to readily develop new modules and applications to interface with the data stored in RiskSpectrum fault tree and event tree models.

The development of this new version is of great importance for the continued development of RiskSpectrum PSA and with this application on the market Relcon Scandpower will remain the most attractive software supplier in its line of business.
Relcon Scandpower has never in the past invested as much in software development as it is doing today. This has been made possible with the increasing number of licensees and the number of licensees with support agreements.

- We are determined to keep delivering software, support and services that exceed our licensee's expectations.

The new version of RiskSpectrum PSA will be released in 2007 and all licensees with support agreement will receive it free of charge.

It all started in 1985 with the release of RELCONīs first software, RELTREE. It was written for the MS-DOS operating system and included a Fault Tree editor and a module for calculating Minimal Cut Sets (MCS).

After two years of development, RiskSpectrum for DOS was released in 1991. This was a great step forward from RELTREE and included more advanced modelling possibilities that at the time were unique.

RiskSpectrum got the reputation of being the most advanced and fastest MCS solving software and was therefore the preferred choice in the nuclear industry for PSA/PRA. Soon it also attracted customers from other lines of business such as the aerospace, defence, transport and communication industry.

Even though PSA/PRA had been very important in the nuclear industry for a number of years, the production and usage of PSA/PRA in the nuclear industry now started to grow all around the world. More and more man-hours were invested in creating larger Fault Tree and Event Tree models. As these models grew, the demand for faster algorithms solving MCS-analysis increased.

In 1992 the complete PSA tool - RiskSpectrum PSA was released. This software was to become the choice of the largest companies in the nuclear, aerospace and defence industries. There are mainly two things that made it so popular. It integrated Event and Fault Tree analysis and the module for producing MCSs was the fastest Fault Tree solving algorithm in the world.

In 1994 the development of a Windows version of RiskSpectrum started and in September 1998, RiskSpectrum PSA Professional version 1.00 was released. This was the third generation Fault Tree software produced by RELCON.

In 2002, RELCON released the first version of a new addition to the RiskSpectrum family, RiskSpectrum RiskWatcher. RiskSpectrum RiskWatcher is a risk monitor that is intended to be used in conjunction with RiskSpectrum PSA Professional foremost at nuclear power plants.

Relcon Scandpower is a company that plans ahead and has a long term strategy for its software development. Due to the products high level of technology, complexity and quality, Relcon Scandpower hire only top level scientists, engineers and software developers.
