Studsvik Scandpower Customer Profiles

The nuclear power industry knows Studsvik is the company for fuel management expertise and cutting-edge software. For almost 25 years, Studsvik has provided world-class software and services to address emerging issues and industry initiatives.

Fuel Vendors

Several fuel vendors utilize Studsvik products for core design assessment and operational support. Although the majority of the fuel vendors still maintain their own analogous software to the Studsvik products, several have found it is simply not cost effective to continue their own development for next generation of these products.

One of the strengths of Studsvik has been to maintain a robust staff of experienced developers and analysts in both steady state and transient analysis associate with incore fuel management. This experience base is lacking in the industry and some fuel vendors have found it beneficial to move to the Studsvik products and concentrate on their own core business which is developing and delivering advanced fuel hardware products.

Operating Utilities

A host of utilities throughout the world are using Studsvik software & services for a range of applications including independent assessment of fuel design changes proposed by their fuel vendor, independent core tracking for operational support, fuel loading pattern development, and optimization of reload shuffling to reduce outage time.

At the reactor site, Studsvik products provide shutdown support for reactivity management, refueling shuffle optimization, expediting an efficient startup, reactivity management and power maneuver forecasting, and shutdown planning. More than ever, older reactor sites must contend with spent fuel issues like degraded poison sheets, pool criticality analysis, and dry storage cask management, and many are finding answers in Studsvik's nuclear fuel analysis software.

At over 50 reactor sites across the world, utilities rely on Studsvik core models to power their operator training simulators. Since the Studsvik core model is cycle-specific, there is no approximating or tuning required to make the training simulator model mirror the actual cycle. Studsvik simulator solutions also allow for the generation of "just in time" training models to respond to events at the plant such as scrams and unplanned mid-cycle outages.

Research Organizations

Several national laboratories and research organizations in countries throughout the world are using Studsvik products. They are involved in critical experiments and analysis of advanced fuel designs which provide valuable experience and benchmarking (in addition to the thousands of cycles of actual operating reactors we have analyzed).

Many of these research organizations are involved in coupling Studsvik products to extended reactor analysis applications, such as fuel thermo-mechanical analysis, stainless steel reflector gamma heating analysis for advanced reactor designs, vessel fluence, and even post-irradiation analysis of spent fuel for comparison to measured isotopic gamma scans.

Significant work has been done by some of these organizations to couple Studsvik core model products to whole-system codes for transient and safety analysis.

Reactor Vendors

Several reactor vendors are using Studsvik products for analysis of new reactor builds. These include organizations involved in modular reactor design and deployment as well as traditional reactor vendors looking at large-scale, commercial nuclear reactor builds.

The same software products used throughout the industry for older-generation designs have proven applicable to these new, next-generation nuclear reactor designs as well. Since many of these organizations are already analyzing today's operating reactors, they can leverage their investment by using same software (and experience of their staff to use the software) to evaluate potential new reactor builds.

  • Mitsubishi Heavy Industries - Nuclear Fuels,
  • NuScale Power,

Safety Authorities

Safety authorities and nuclear regulatory agencies worldwide use Studsvik products for vendor and utility oversight. Using Studsvik products they are able to capitalize on the same benefits that other types of organizations receive - access to Studsvik's cutting edge, accurate analysis software and services. Studsvik software allows safety authorities to confirm vendor calculations, proposed core designs, and analyses submitted for review on a consistent, easily comparable basis. Safety Authorities using Studsvik solutions

  • Armenian Nuclear Regulatory Authority,
  • Atomic Energy Council,
  • Canadian Nuclear Safety Commision,
  • Japan Nuclear Energy Safety Organization,
  • Nuclear Safety Council,
  • State Scientific and Technical Center,
  • Swedish Radiation Safety Authority,
  • Swiss Federal Nuclear Safety Inspectorate,
  • TÜV NORD Nuclear,

Service Companies

Engineering service companies provide support to operating utilities that may not have the manpower or expertise to perform their own nuclear core analysis. Some of these service companies provide utilities with vendor-independent oversight or confirmatory calculations to verify the fuel vendor proposed core design using Studsvik software. Others have helped utilities maximize the benefit of having the a fuel vendor-independent solution by licensing with the safety authority the application of the Studsvik codes to perform their own core design. Still others assist utilities generate a core design maximized for their plant, rather than being forced to accept a generalized design developed for similar reactors.

Service Companies using Studsvik solutions

  • NIS Ingenieurgesellschaft,
  • Nuclear Engineering, Limited,
  • West Japan Engineering Consultants, Inc.,

Criticality Safety Companies

Companies involved in criticality safety and spent fuel analysis are using Studsvik products for specialized applications not directly involved in core design or operational support. Studsvik core analysis techniques have proved invaluable for analyzing wet and dry spent fuel configurations, as well as cask loading optimization, spent fuel isotopics, and heat load.
