New detection unit designed and released

Within the scope of the contract for supply of radiation monitoring system for the PIK high-flux reactor atB.P. Konstantinov Petersburg Nuclear Physics Institute, SPC Doza in cooperation with State Research Center “Institute for High Energy Physics” (IHEP) of the NRC Kurchatov Institute designed a new detection unit BDPN-101D for measuring the thermal neutron flux density. Design and specifications of the unit were developed taking into account safety requirements and design documentation of PIK reactor. The unit consists of a thermal neutron detection module and interface module.

Main specifications:

Detector type3He counter
Measuring range of intermediate neutron flux0,02 ÷ 2·103neutrcm-2s-1
Limits of basic relative measurement error±30 %
DC supply voltage12 V
Current consumption400 mA
Dimensions220×166×87 mm
Weight1 kg
Operating conditions:
⦁ambient temperatureminus 10 ÷ +60 °C
⦁relative humidityup to 98 % at 35 C

Detection unit BDPN-101D is listed in the State Register of measuring instruments under No. 65959-16 and was approved by the I.I. Afrikantov OKBM for use at universal nuclear-powered icebreaker of Project 22220.
