Description

The SGLM 510 monitor is part of the proTK / 260 series product line. It has been designed to detect leakages between the primary and the secondary circuits in a nuclear power plant. It operates on the principle that radioactive isotopes like N-16 that are only present in the primary circuit during normal operation cross the boundary into the secondary circuit due to a leak in a steam generator tube. The radioactive isotopes are transported through the main steam line and detected by measuring the increased level of gamma dose rate on the main steam line outside the containment.

The SGLM 510 monitor offers a wide measuring range and a processing unit designed for Cat. A safety functions.

SGLM 504 Steam Generator Leakage Monitor

Used for detecting the gamma radiation from activation or ﬁssion products in the secondary loop of pressurized water reactors (PWR), which is an indication of a leakage in the physical barrier between the primary and the secondary loop (e.g. N-16 or radioactive noble gases in the main steam line).

SG 65/66 NaI Scintillators

The SG 65 and SG 66 scintillators have been developed for safety related monitoring of activity according to KTA 1502. In the scintillator crystal, ionizing radiation generates light pulses, which are converted and ampliﬁed into charge pulses by the photo multiplier.

The height of the pulse is proportional to the energy of the gamma radiation. An adjustable pulse ampliﬁer offers calibration of the sensitivity and matching of the output pulses to the impedance of the detector cable.
