Noise Analysis Measurements and Numerical Evaluations of the Moderator Temperature Coefficient in PWRs

Laggiard, E.; Grundmann, U.; Rohde, U.; Weiß, F.-P.; Runkel, J.; Stegemann, D.

The moderator temperature coefficient (MTC) of a 1400 MW pressurized water reactor (PWR) has been measured from neutron and temperature fluctuations in different reactor positions. In order to explain the deviations observed between the estimations, numerical evaluations of the MTC were performed using the 3D two energy groups DYN3D code for a prototype PWR. The differences between the experimental MTC estimations can be partially explained considering that the numerical MTC evaluations show a definite devitation of the neutronics from point kinetics.
