Nuclear Power Plant Support Services Provided by NTS, Inc.
RADIATION MONITORING
SYSTEM ENGINEERING SUPPORT
NTS
can provide on-going or one time primary on-site calibration
services. Typically, effluent radiation monitors should have a
primary calibration performed every five years at minimum. This in-situ calibration would document the sensitivity of the existing
monitor system, and could establish “fresh” transfer sources for
the periodic transfer calibration required for general maintenance
activities:
NTS
staff has provided in-situ primary calibrations of Kaman accident
rage monitoring system at Hatch Nuclear Plant; Eberline Sping gas
effluent monitoring systems at Clinton Nuclear Power Station and
High Range ventilation stack monitor at Browns Ferry Nuclear Plan
complying with Regulatory
Guide 1.97 (NEREG 0737) requirements. Along with the in-situ
calibration services NTS also provided routine calibration
procedures, procedures for alarm set points etc.
NTS
has personnel resources with background of industry experience
supplying state-of-the-art monitor design, fabrication, analysis,
and installation of radiation monitoring systems of various types;
radiochemical testing; health physics documentation; system
maintenance and repair. NTS also provides an on-site one to two-day
seminar; “WORKING WITH RADIATION MONITORS,” for the engineering
and maintenance staff, which can be presented as a supplement to
training or as a lecture on problems and solutions based on varied
experiences.
The discussion includes basic theory of operation of
detectors, their application and general design requirements, and
system calibration requirements from ANSI standards to EPRI
suggestions. The discussion is addressed both from a user (Plant
System Engineer) standpoint and as the equipment vendor/designer.
NTS
is capable of providing plant staff assistance in resolving
radiation monitor problems either onsite or off-site with the direct
input from the operating staff. NTS can provide a focused
direction to the maintenance staff for repair or upgrade for a
single monitor or for the entire radiation monitoring system.
