Performing Thermal Hydraulic Safety Analysis for Nuclear Power Plants 2nd Edition

  • Àrea: Energia
  • Modalitat: Presencial
  • Data inici: 10/06/2019
  • Localització: Barcelona


This 2019 course is the 2nd edition of the training "Performing Thermal Hydraulic Safety Analysis for Nuclear Power Plants". It is taught by lecturers at the Technical University of Catalonia (Barcelona).
The target of the course is to enhance the comprehension of Safety Analysis for the young professionals that recently started to work in PWR type nuclear power plants, for analysts from the regulatory body and for individuals who may be interested in the field of Safety Analysis.

Objective of the course:

The course objective is to enhance the understanding of complex systems behavior taking place in accidental scenarios in nuclear power plants. Also to understand the link between the plant behavior results and the work performed by analysts or engineering support companies at the power plant. The course will focus on relating the previous knowledge on PWR plant systems with the following topics: (1) Transient and Accident Analyses (Chapter 15) required at plant's Final Safety Analysis Report and (2) Beyond Design Basis Accidents, that might be part of required studies from the regulatory bodies.


The seminar is open to vendors, utilities, regulatory bodies, national laboratories, consulting companies and universities.


The course is divided in two parts:

I. USNRC's Safety Analysis Report (SAR) Chapter 15 Design Basis Accident (DBA).

II. Safety Analysis to be performed for Beyond Design Basis Accident (BDBA).

In the first part, an introduction on regulations, plant design and relevant plant documentation is performed. The block is focused on the relationship between DBA and the plant design, the acceptance criteria and the Technical Specifications. The first part is divided in blocks 1 and 2.

In the second part, several approaches to BDBA Safety Analysis are introduced. Specific cases will be studied related to SBLOCA and SBO scenarios. In addition, special focus will be given to the plant response and the design of FLEX systems within BDBA scenarios. Block 3 is associated to the second part.

Dr. Jordi Freixa has about 16 years of experience in the use of TH system codes. During this time, he has developed or worked with more than 10 full plant models. His main areas of research are the validation and application of best estimate thermal hydraulic codes for LWRs.
Daniel Suàrez has an experience of 8 years training NPP operators including full scope control room simulators at Tecnatom S.A. During this time, he has studied operators responses to DBA and BDBA in actual power plant condition. At this time he also works as assistant professor and is also finishing his PhD in nuclear fusion related technology.
Max Casamor has an experience of 7 years in training NPP operators including full scope control room simulators at Tecnatom S.A. He is now a granted full time PhD student finishing his thesis on coupling CTF subchannel code and RELAP5 system code.
