SN-D-2™

Description

The SN-D-2 probe for measurement of neutron dose equivalent rate is designed to be used with any CSP survey meter or any computer-based system developed within CSP environment. Its 8 atm ³He gas detector associated with a 200 mm polyethylene sphere, brings a best-in-class neutron efficiency and, an excellent Gamma rejection.

SN-D-2 probe's lightweight makes it an ideal tool for direct measurement of neutron ambient dose equivalent in reactor building during outages or on spent fuel transportation container, prior to shipment to reprocessing plant. A specific tripod can accommodate various heights and distances to the measurement scene while the user remains at a safe area with remote control, supporting ALARA principle.

Its measurement range starting from 300 nSv/h allows controlling neutron public limits within less than a minute. Most CSP meters can also improve MDA with the use of scaler-timer function whenever necessary. The top of range ending at 100 mSv/h supports occupational dose-rate monitoring in radiation controlled area.

The SN-D-2 probe includes an embedded carrying handle making it easy to move to the area to be monitored. Dedicated meter holders adapt each of the available host instruments to complete the probe as a one-hand operational system. It can also be connected via CSP-COM™ modules to integrate third-party system and behave as a neutron sub-assembly.

SN-D-2 probe can be calibrated and upgraded (probe’s firmware) via CSPS software, a USB cable and a PC. It connects to survey meter via a 1.5 meter, 10 meter or 20 meter CSP cable.
