Palo Verde provides the following response: Palo Verde uses the Eberline PNR-4 and calibrates to 4.5, 24, and 202 mrem/hr with a AmBe neutron calibrator and pulses to an equivalent of 2.5, 25, 250, and 2,500 mrem/hr
Electronic pulse calibration is considered an acceptable practice We are committed to ANSI N323-1978 From: [email protected] [mailto:[email protected]] On Behalf Of Danek, Joe Sent: Thursday, July 12, 2012 12:58 PM To: [email protected]; Danek, Joe Subject: Powernet: Calibration of neutron survey meters For ASP1/NRD's (?) neutron survey meters, calibration currently sent to a vendor for annual calibration. The vendor's neutron source allows for calibration up to 200 mrem/hr. For the higher range, up to 1000 mrem/hr, electronic pulse calibration is performed. Please provide responses for; 1). What do you do for calibrations, and particularly at the higher range? 2). Is electronic pulse calibration an acceptable practice ? 3). In addition to ANSI N323-1978 & ANSI N323A-1997, can you list any other reference documents, and in particular for use of electronic pulse calibrations?
