WL-23084

Miniature fission chamber with integral coaxial cable designed for in-core neutron flux mapping with a Teleflex or similar flux mapping system. Minimum thermal neutron sensitivity of 1.0 x 10-17 A/nv and a maximum gamma sensitivity of 3.0 x 10-14 A/R/hr.

Designed to detect thermal neutrons in the flux range of 10 to 10⁶ neutrons/( cm 2 - second). The counter is extremely rugged and will operate in any orientation at temperatures up to 570°F (300° C).

Designed for in-core operation in either BWR's or PWR's. The chamber is constructed from stainless steel with high pur­ity alumina insulation and will operate in any position, at temperatures up to (400°C) 750°F.

Designed to detect thermal neutrons in the flux range of 6 to 6 x 10 5 neutrons/(cm 2- second). The counter is extremely rugged and will operate in any orientation at temperatures up to 570EF (300EC).
