USSR.A reactor with an outer control-rod zone can be designed in such a way that a long life span can be achieved. In a given reactor capacity of 20 Mw the change in time of the control-rod position in the critical stage is investigated, giving due consideration to burn-up, poisoning, and conversion. The calculation of the behavior in time was first made within the scope of a modified one-group theory and then in the scope of a three-group theory. It was established that the modified one-group theory is useless for long-term calculations. The advantage of this reactor is the high degree of conversion in the outer zone. (Author)
