Resumo
This paper presents the design of the Emergency Core Cooling System (ECCS)
for the IEA-R1 pool type research reactor. This system, with passive features, uses
sprays installed above the core. The experimental program performed to define
system parameters and to demonstrate to the licensing authorities, that the fuel
elements limiting temperature is not exceeded, is also presented. Flow distribution
experiments using a core mock-up in full scale were performed to define the spray
header geometry and spray nozzles specifications as well as the system total flow
rate. Another set of experiments using electrically heated plates simulating heat
fluxes corresponding to the decay heat curve after full power operation at 5 MW
was conducted to measure the temperature distribution at the most critical position.
The observed water flow pattern through the plates has a very peculiar behavior
resulting in a temperature distribution which was modeled by a 2D energy equation
numerical solution. In all tested conditions, the measured temperatures were shown
to be below the limiting value.
