APPARATUS FOR MEASURING THE POWER LEVEL OF HEAVY OR LIGHT WATER MODERATED NUCLEAR REACTORS

Patent ·
OSTI ID:4148078

The apparatus described utilizes Cherenkov radiation generated by beta particles in the moderator for measuring and/or monitoring the power developed in a reactor. This apparatus comprises a transparent light pipe, which is arranged so that the light generated by the Cherenkov effect is transmitted from the moderator within the reactor vessel to a photoelectric device outside the reactor shielding. The light pipe is bent at least twice, so that no nuclear radiation can escape along it. (Gmelin Inst.)
