1. REACTOR 0?: RATIO::S, Tr.e reactor was operated at full power durinE the entire acnth of September in continuation of the chemical shin progran and the defected fuel rode experiment. The main c::ltnt r; sten boror concentration war reduced from 640 p;n to 521 ppn during th r rtn t: :ompensate fer fuel depletion.

2 EXPERI!E"TA: PROGPJM Depletion data and fl x wire data were ebtained during the month. The defected fuel rad cladding test was centinued throughout the month. The purification s;' sten deminera'icer was operat ed for 12 heurs at approximately 11 gpm tc. help in evaluating 9e fission product release fron the defected fuel rods. A ruccessful test run was madt with two miniature in-:cre detectore connect ai t: the flux wire drives.

A ficu meter was innalled in the process liquid inlet line to the INDF evaporator.

A liquid level sight glass was installed on the RJDF evaporator.

A three-way soleneid valve was installed in the discharge line of the RWDF evaporator hotuell pump. The valve functions to dump the water in the hotwell to the radioactive water drah. r/ sten in the event of radioactive carry-over from the evaporator.

6. CHmISTRY The main coolant system was maintained at operating conditions throughout this report period. The main coolant boron concentration was adjusted in accordance with the chemical shim program, On September 4th the boron was reduced from 641 p;n to 600 p;n, en September 15th to sta ppm, and on September 24 to 521 ppm. The purification deminerali: er was placed in service on September 24th for 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.

After 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> of operation the main coolan 15 minute activity (gross beta-ga=ma) 'was reduced from 0.669 ue/cc to 0.346 ue/ce. The main coolant total alkali (M/L x 10-4) increased from 1.183 to 1.856 during this period. A summary of the main coolant chemistry analyses made during the month are contained in the following table:

Orc 3s Seta-Gama, ue/cc .346 .853 Steam generater chlorides were maintained below 0.?.70 ppm with a constant blowdown rate of 1000 lbs/ hour. Tne average activity of the steam generator blowdown continued to be less than 1 x 10-6 ue/cc.

7. RADIATIO:; A!D UASTE DISPOSAL Radiation surveying consisted of routine plant site surveys, EdDF, vaste storage area, shipment of radioactive material samples, and waste drums prior to and after mixing. The following raxinum readings were taken:
