In Section 2.3 it was shown that — in principle — 3 different loops exist in the NOKO facility. For the tests with the emergency condenser as the test section this configuration allowed the

evaluation of the energy transferred by the emergency condenser by three different and independent balances:

I) The steam flow to the condensers was measured with an orifice.

II) The steam flow to the condensers was calculated from the power input by the boiler and

pumps, the heat losses and the energy removal by cooling.

III) If the water pool was at saturation temperature, the steam was measured using an orifice.

The comparison of these three balances increased the confidence in accuracy of the results.
