| Title: | Reactivity worth of control rods in the beryllium oxide moderated pebble bed reactor. |
| Authors: | Spinks, N |
| Issue Date: | Feb-1967 |
| Publisher: | Australian Nuclear Science and Technology Organisation |
| Abstract: | Preliminary and final studies are reported for the worth of tubular control rods in a beryllium oxide moderated pebble bed reactor system. In the preliminary study the consideration of ball flow forces the investigation of a number of control rod arrangements. In addition, a range of rod sizes is considered. In the final study a particular rod size and pattern is chosen for more detailed investigation. For the intermediate reactor cores under consideration the control rods must absorb appreciably in the KeV region. A feature of the final study is the accurate way the epithermal absorption can be taken into account while using a three group model in the reflected reactor. The preliminary study is not so accurate but is useful for comparative purposes. |
