3. DESCRIPTION
In 1996-97 a number of tests with the high burn up VVER-440 fuel under transient conditions were carried out in the MIR reactor (SSC RIAR). Fuel rods that had operated under normal operating conditions at the Kola NPP Unit 3 during 4- and 5 fuel cycles up to the maximum burnup of about 50 and 60 MWd/kgU were tested. The tests were carried out under single ramp conditions (RAMP experiment) and step by step power increase (FGR-1 and FGR-2 experiments). The objective of the experiments was to determine the power ramp influence on fuel rods state, to evaluate FGR induced-threshold linear power values, to study dependence between the linear power, temperature, structure and properties of the fuel.
Nine refabricated fuel rods were tested in the above mentioned tests. All of these refabricated fuel rods (RFRs) were cut from fuel rods of the FAs 198 and 222. The positions of the RFRs, the average linear heat rate of the FAs 198 and 222 fuel rods during base irradiation, the operating conditions of the FA-198 and FA-222 fuel rods, details of the design values of the FA's 198 and 222 fuel rods and the main operating conditions of the Kola 3 during 5-9 fuel cycles are provided.
RAMP test:
The test rig with RFRs was installed for testing in the research reactor MIR in February 1996. During the RAMP experiment 3 non-equipped RFRs were tested under power ramp conditions. The RAMP test was divided into 3 stages: stage 1 - irradiation at initial power level (duration - ~346 hours); stage 2 - power ramp from initial to maximal level (duration - ~23 min); stage 3 - hold stage after ramp (duration - ~107 hours).
FGR-1 test:
The FGR-1 experiment started in March 1996 and finished in April 1996. The test rig included three RFRs. Two were instrumented with pressure sensors while the third was not instrumented.
FGR-2 test:
The FGR-2 experiment was the second of the tests series directed to investigation of the thermal physical behaviour of VVER fuel at the different power levels. It was carried out during April-June of 1997. The test rig included three RFRs, two of which were instrumented with thermocouples, and the third was not instrumented.
