Projects recently completed by Red Wolf Associates include:

• Secondary containment positive pressure period / drawdown analysis using GOTHIC
• Intermediate building heat-up analysis to support operator response to fires using GOTHIC
• Long-term post-LOCA secondary containment heat up analysis with GOTHIC
• Updating of temperature response analyses for Diesel Buildings, ECCS pump rooms, and other areas of PWR and BWR facilities with GOTHIC
• Benchmarked and evaluated cooling coil performance and water-side system response to assess the impact of various postulated equipment and sensor deficiencies/failures on system performance utilizing GOTHIC

Red Wolf personnel have intimate experience with the GOTHIC thermal hydraulic code including extensive application, benchmarking, code development and testing, underlying constitutive model development, user support, and delivery of training. Listed below are a few of the areas in which Red Wolf Associates consultants have previously utilized GOTHIC:

• Analyzing containment thermal hydraulic response following postulated accidents for PWR containments as well as Mark I, II, and III BWR containments, including benchmarking against older codes
• Performing room heat up analyses for various purposes such as equipment qualification, Appendix R fire analysis, and secondary containment drawdown
• Modeling detailed piping systems to determine NPSH, investigate gas intrusion in safety systems, and estimate fire protection system operability
• Developing detailed reactor coolant system models to calculate time to boil following loss of RHR cooling, develop time to boil curves, and estimate long term mass and energy releases for both PWRs and BWRs for containment analyses

Our staff is also familiar with other thermal hydraulic codes such as RETRAN, CONTEMPT, CONTRANS, COPATTA, and LOCTIC.

Additionally, the personnel of Red Wolf Associates have extensive experience determining atmospheric dispersion factors with codes such as ARCON96, PAVAN, and XOQDOQ, assessing control room habitability due to postulated releases of hazardous chemicals utilizing programs like HABIT, and performing radiological shielding analyses with computer programs MicroShield and QADMOD-GP.
