NEA-1536 IFPE/TRIBULATION R1.

1. NAME OF EXPERIMENT:  IFPE/TRIBULATION.

3. DESCRIPTION

The TRIBULATION (Tests Relative to High BUrnup Limitations Arising Normally in LWR's) International Programme started in July 1980 and was organized jointly by BelgoNucleaire and the Nuclear Energy Centre at Mol (CEN/SCK) with the cosponsorship of 14 participating organizations.
The objectives of the programme were twofold. It was primarily a demonstration programme aimed at assessing the fuel rod behaviour at high burn-up, when an earlier transient had occurred in the power plant. The second objective was to investigate the behaviour of different fuel rod designs and manufacturers when subjected to a steady state irradiation history to high burn-up.
The first objective was met by irradiating fuel rods under steady state conditions in the BR3 reactor and under transient conditions in BR2. The effect of the transient was determined by comparing data from 4 identical rods tested as follows:
i)   BR3 irradiation followed by PIE
ii)  BR3 irradiation followed by BR2 transient then PIE
iii) BR3 irradiation followed by BR2 transient and reirradiated in BR3 before PIE
iv) BR3 irradiation and continued BR3 irradiation to maximum burn-up before PIE.
The Database contains data from 19 cases using rods fabricated by BelgoNucleaire (BN) (11) and Brown Boveri Reactor GmbH (BBR) (8).
