1. Fuel Rupture Location System

The six-cyclone pro to type of the rupture l o c a t i n g system pro- posed for n a t u r a l f u e l r e a c t o r s has been rece ived and is being i n s t a l l e d a t Savannah River Laboratory f o r hydraul ic t e s t i n g .

Design of the automatic device f o r r a d i a t i o n scanning of banks of cyclones has been completed i n the Mechanical Assis tance Sec t ion a t the Savannah River P lan t , and the AC photomulti- p l i e r c i r c u i t r y proposed f o r the de tec t ion system is under t es t i n "L" r e a c t o r .

An inc rease i n pressure of the b lanket gas system t o 5 psig is being considered w i t h the ob jec t ive of i nc reas ing the hydraulic ( temperature) l i m i t s on the r e a c t o r s . However, i n order t o avoid l i f t i n g 'the plenum during opera t ion w i t h l i g h t - weight enr iched loads, the plenum must be f a s t ened t o the floor or t o the r e a c t o r s t r u c t u r e , Holding the plenum down by means of the f o r e s t s t r u c t u r e appears impract icable because of the large f o r c e s involved. Study by the Engineering Department has shown tha t f a s t e n i n g the plenum a t i t s periphery would s-till permit enough c e n t r a l d e f l e c t i o n t o cause b inding on the semi- permanent s l eeves . The proposed method of f a s t en ing , t he re fo re , i s t o i n s t a l l t i e b o l t s i n 30 t o 50 of the a v a i l a b l e instrument holes , to t i e the plenum t o the top shield. The gas pressure r equ i r ed t o l i f t the plenum and shield toge the r would.be about 13 ps ig with a n a t u r a l load of about 8 ps ig w i t h an enriched load , A c o s t estimate has been requested for i n s t a l l a t i o n of the t i e b o l t s .
