ΕΠΙΔΡΑΣΗ ΑΝΟΜΟΙΟΜΟΡΦΗΣ ΑΝΑΔΡΑΣΗΣ ΣΤΟ ΟΠΤΙΚΟ ΠΕΔΙΟ ΑΝΙΧΝΕΥΤΗ

A Λ-D MODEL OF SPACE DEPENDENT FEEDBACK IN BWR'S IS PRESENTED. EQUATIONS ARE SOLVED NUMERICALLY WITH THE METHOD OF FINITE DIFFERENCE APPROXIMATION TO DERIVATIVES. IT WAS FOUND THAT FEEDBACK WILL, IN GENERAL, REDUCE THE DETECTOR FIELD OF VIEW AT LOW FREQUENCIES, IN AGREEMENT WITH PREVIOUS INVESTIGATIONS, BUT THE COUPLING OF DIFFERENT FEEDBACK MECHANISMS MAY REVERSE THIS EFFECT. THE MODEL IS THEN MODIFIED TO A FORM AMENABLE TOP ANALYTICAL SOLUTION AND IT IS CONCLUDED THATSPACE DEPENDENT FEEDBACK MAY INCREASE, DECREASE OR EVEN DISPLACE THE DETECTOR FIELD OF VIEW. LAST BOILING AND PRESSURE FEEDBACK EFFECTS ON NEUTRON NOISE ARE INVESTIGATED. IT IS CONCLUDED THAT THE STRUCTURE OF NEUTRON NOISE COHERENCES ATLOW FREQUENCIES CAN BE EXPLAINED BY EITHER PRESSURE OR/AND BOILING FEEDBACK.
