Sodium Loop for the Investigation of the Fuel/Sodium Interaction with Electrically Heated UO sub 2.

摘要

An out of-pile test facility has been erected for investigation of the fuel-sodium interaction taking place after power excursion. This facility allows melting down of up to 7fuel pins arranged in bundles through direct electric heating in flowing sodium. The maximum active UO sub 2length in the fuel pin is 160mm. The cooling and hydraulic conditions in the test section have been chosen similar to that in the SNR fuel element,although they are variable. In the course of testing 27measuring values at the maximum are recorded in an analog mode on magnetic tape. They are digitized and evaluated using the SEDAP program system. (ERA citation 02:029852)
