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?
Thank you, Joe Danek Corporate RP Florida Power & Light / NextEra Energy [email protected]
