Discussion on transients

MR D. VAN ESSEN, B. V. Neratoom, The Netherlands

In Paper 13 the stability code is validated

against experimental results using SNR 300

modules. As these modules have not yet operated

I assume the Authors are referring to prototype

steam generators.

Did the Authors obtain the test results from

the evaporator or the superheater? Also how did

they calculate the steady state conditions

within the bundle region? This requires a two

dimensional calculation.

MR VAIDYANATHAN, Paper 13

The stability data used for the validation of

the code was obtained from the prototype SNR

modules which were the subject of experiment at
