Red Wolf Associates provides analyses in support of reducing outage time as well as other cost savings measures. An example of this type of analysis is development of a GOTHIC model that predicts the time to boil or core uncovery in the primary system of a PWR following loss of RHR cooling. The GOTHIC model may demonstrate that natural circulation provides adequate cooling of the core over a given time period. One benefit in having such an analysis may allow the plant to take a train of RHR cooling offline earlier in the refueling outage process, thereby possibly providing schedule flexibility and cost savings. Another similar example is creation of a GOTHIC model to determine time to boil curves for the primary system.

GOTHIC models of BWR vessels may also be developed in conjunction with containment models to support revisions to procedures that may allow for reduction in refueling outage durations. An example includes early draw down of the upper containment pool during Mode 3 in Mark III containments.

Red Wolf Associates personnel also have experience applying GOTHIC in other unique manners such as modeling air flows and heat transfer in industrial processes demonstrating improvements in processes resulting in cost savings.
