Recent research of the UPM Nuclear Safety Group with the GOTHIC code

The simulation of large enclosures, in particular Nuclear Power Plant containments has been a challenge since the early modeling attempts, motivating the use of Lumped Parameters models. However, the increasing computational capability, the recent effort in code development together with the accuracy loss because of the hypotheses used in the mentioned approach have propitiated the use of three dimensional models.

In this regard, the UPM has developed a research line to deepen into the three-dimensional capabilities of the containment code GOTHIC. During the first years, the UPM focus was on developing a methodology to model the different scenarios in an efficient and reliable manner. Then, different applications of the GOTHIC code were performed.

These applications include the analysis of Design Basis Accidents or Severe Accidents for different containments and phenomena (PWR-W, BWR, KWU, AP1000/CAP-1400). Additionally, the GOTHIC code has been used in a benchmark simulating light gas diffusion in the PANDA facility, it has also been used to assess the filtered containment venting system of a BWR and a high energy steam injection in a suppression pool.

All mentioned applications will be depicted and summarized during the seminar, finalizing with current research lines and trends of GOTHIC and the UPM.
