To improve the design and fabrication quality of reactor components and systems, in order to increase operation reliability and hence safety and economy of nuclear power plants, and to develop models and computer codes which describe the phenomena occurring during the course of an accident.


Simulation tests were carried out in the LOBI (LWR Off-normal Behaviour Investigation) out-of-pile depressurization facility and a test programme was prepared to simulate large and small breaks in the light-water reactor (LWR) primary circuit, using the Super-Sara in-pile facility.

On 19 May 1981 the Council approved the continuation of the Super-Sara project (Official Journal No L 72 of 18.3.1980), JRCs most important experiment on reactor safety. The purpose of this project was to study the behaviour of the fuel in a light-water-type nuclear reactor under abnormal operating conditions, and in particular in the event of a loss of coolant such as that which occurred during the accident at Three Miles Island in the United States.

The JRC contribution to safety research on liquid-metal fast-breeder reactors (LMFBRs) concentrated on abnormal events which have a very low probability factor but which might have serious effects on the integrity of the plant. Important milestones were the publication of the European Accident Code (EAC) and the start of an extensive in-pile research programme to solve post- accident heat removal (PAHR) problems. A materials-testing programme was launched in support of LWR and LMFBR safety research.

Special efforts were also made in the reliability and risk assessment project, prior to the introduction of a centralized databank system for LWRs.

The collection of data relating to reactors in the Community and the improvement of information technology structures contributed to the development of the European reliability Data System (ERDS), which is now regarded as an indispensable tool for probabilistic risk assessment.


Eleven projects:

- Project LOBI:
Study of loss of coolant accidents in light-water reactors;

- Project Super-SARA:
An in-pile experiment on the behaviour of light-water reactor fuel in the event of loss of coolant;

- Project LWR primary circuit integrity:
Early detection of faults in light-water reactor vessels;

- Fast-breeder fuel sub-assembly thermohydraulics;

- Mechanical tests of fast-breeder structural materials;

- Development of fast-breeder hypothetical accident codes;

- Project PAHR (Post-Accident Heat Removal):
Study of the evacuation of residual heat in a fast-breeder molten core;

- Project PAHR in-pile;

- Study of fuel-coolant interaction under accident conditions;

- Study of the behaviour of structures and containments subjected to accidental stresses;

- Analysis of reliability, risk assessment and data bank.
