The OECD Halden Reactor Project is an undertaking

of national organisations in 19 countries

sponsoring a programme that provides key

information for safety assessments and licensing

as well as for the reliable operation of nuclear

power stations. The programme is using the Halden

reactor, the Kjeller hot laboratory, the Halden

Man-Machine Laboratory, the FutureLab

and the Halden Virtual Reality Centre for experimental


The activities in the Fuels & Materials area provide

fundamental knowledge on the properties

and behaviour of nuclear fuels and materials

under long-term use in reactors as well as

during transients. In 2012, fourteen in-core

tests were executed, most of them in loops

simulating the thermo-hydraulic conditions of

LWRs. In addition, seven tests were in preparation,

and four underwent PIE. The tests encompassed

various types of fuels and materials

with zero to high burnup or neutron fluence.

The LOCA test series continued with a pre-

irradiated BWR fuel rod. In-core materials were

tested to obtain data on stress corrosion cracking

and stress relaxation of reactor materials for

plant lifetime assessments.

The research in the Man-Technology-Organisation

area comprises empirical studies of

the interaction between the reactor operators

and process control systems. It also comprises

innovative work on Human System Interface

design and Control Room design. 3D visualisation

technologies by means of Virtual and

Augmented Reality are being developed. During

2012, the final report was issued of the

International empirical validation of various

HRA methods. Various future operational

concepts were prototyped to study highly automated

advanced plants. Improved methods

and techniques for plant state monitoring and

plant performance optimization were tested.

Software systems dependability addressed

issues related to modernisation of digital I&C

systems, requirements engineering, risk assessment,

and error propagation.
