The current operating conditions at 105-DR, because of the recent Ball 3X drop, dictate temporary lower speed-of-control limits. While is si still not expected that this reactor will be limited by the speed-of- control criterion, it is felt that the limit curves have been temporarily sufficiently reduced as to warrant publication of former limits. Limit curves as a function of weighted graphite temperature for the continuous and block discharge schemes are included in this document. The two sources of the reduction in the speed-of-control limit comes from two sources: (1) While the limit is commonly expressed in MW of pile power level, it is actually a function of maximum tube power, (2) The poisoning effect of the balls lodged in the stack has been estimated at about 15 mk.
