Our Services

RSC Specializes in assessing your situation and not in providing a generic solution.


RSC staff supported the licensing of Watts Bar using statistical analysis to place perceived issues into focus.


RSC supported Kernkraftwerk Mühleberg in developing a full-scope shutdown assessment

PRAMS, DBM, SIP and other RSC-developed tools can provide clients with immediate benefits and better access to their information.


 

RSC-developed training can bridge the gap and provide qualification training for client staff.

RSC provides a full range of PSA and reliability services for nuclear and non-nuclear clients. The RSC team members have a high degree of technical and project management experience. Their varied backgrounds in deterministic and PSA applications provide a broad knowledge of different analysis approaches that can be applied as needed to accomplish a project. This broad basis allows easily assimilation of information or work products generated by other organizations. The team's experience has been demonstrated by a history of successfully completed projects within budget and schedule and by a continuity of client requests for follow-on support.

In addition to RSC’s staff and independent contractors, RSC maintains partnering relationships with other PSA and engineering support companies that provide various products and services. This relationship allows RSC to expand its own capabilities when necessary to address specific client needs. The selection and oversight of specific experts from these companies by RSC ensures the quality of the final product.

RSC can provide support in any area of probabilistic analysis has considerable experience in the performance of all aspects of PSA.  Therefore, RSC can support clients in the development, update, or maintenance of any of the following areas: (click a topic for more detail)

RSC can generate graphical or tabular aids necessary to support SAMG development.  RSC can also provide support to the utility to assist in their production.  For example, RSC has developed and automated several important graphical aids required for the Westinghouse severe accident guidelines. These graphical aids produce the graphs needed and allow for easy documentation and updates.

RSC has comprehensive experience in severe accident evaluation including probabilistic risk assessment, accident progression, and phenomena evaluation.  This extensive knowledge base provides RSC with the tools necessary to develop a plant-specific implementation of the generic guidance.  RSC can develop a set of recommendations for your plant that identifies where the generic guidance should be augmented to address plant-specific severe accident characteristics.
