3. DESCRIPTION

The  release of fission products from irradiated UO2 into  the fuel-clad  gap  of  a sound rod has been studied  extensively, both  theoretically  and  experimentally.   By  contrast  very little  is  known about the behaviour within a defective  rod, where the pressure of water or steam in the gap may modify the processes of release from the fuel, through the defect, to the coolant.

A series of loop experiments have been performed on short fuel rods  by  CEA  in  France  with  the  aim  of  measuring and interpreting  the  release rate of fission  gases  and  iodine under  a  range  of experimental conditions of  linear  power, defect type, gap dimensions etc. The  results  from  these experiments,  which  cover steady state  and  transient  power operation  on new and pre-irradiated fuel, provide  invaluable data  for  modelling  the  escape  of  fission  products  from defective  fuel rods. In a commercial reactor, such  modelling is  important for assessing the occurrence and characteristics of defective fuel from analysis of coolant activity. Knowledge of  the presence of defective fuel can eliminate the need  for premature shut down of the reactor and a also minimizes outage time,  thus  improving  the  safety  and  economics  of  power generation.

The experiments were all performed in the Siloe reactor in one of two water loops called Bouffon and Jet Pompe.

The  Bouffon loop consists of two vertical tubes connected  at both  ends to form a continuous circuit for pressurised water. The  experimental fuel rod is situated in the  bottom  of  one tube below a heater which provides an up current of water  and hence  by  thermosyphoning, a flow of cooling water  over  the experimental fuel rod.

The Jet Pompe loop comprises two co-axial vertical tubes.  The experimental  fuel  rod  is situated in  the  inner  tube  and coolant  flow over it is provided by a steam injector pump  at the  bottom of the same tube.  The steam at 400 C and 35  bars is  obtained from a steam generator installed elsewhere in the rig.

The CEA Defect Fuel experiments are CYFON 1, CYFON 2, EDITH 1, EDITH 2, EDITH 5, CRUSIFON 1BIS, CRUSIFON 1 and CRUSIFON 5.
