General Information

1.1 Introduction

The equipment described in this manual is designed for use at the Simulator Facility of Rochester Gas
and Electric’s Ginna Nuclear Power Station. The simulator equipment provided mimics the redundant
Control Room Air Intake Monitors identified as channels R45 and R46. These channels provide a
continuous display of gamma radiation dose rate in the intake duct. The displayed units are mR/h.

The equipment comprising the simulator channels is listed below:

• Model 956A-201-S1, Universal Digital Ratemeter Simulator

• Model 948B-1-5 Rack Chassis, dual bay

• Model S14283A101, Action Pak, 4010 series

The 956A-201-S1 and 948B-1-5 are designed by Fluke Biomedical, Radiation Management Services. The
S14283A101 is designed by Action Instruments.

1.2 Equipment Overview

This section is a brief overview of each piece of equipment utilized for each of the two simulator channels.
A description of the equipment is contained in the following paragraphs. For further information on
individual pieces of equipment, refer to the Standard Manual located in Appendix D.

1.3 Universal Digital Ratemeter Simulator 956A-201-S1

The model 956A-201-S1 is voltage or current driven device used to simulator the display and alarm
function of the 956A-201 Ratemeter. The display range is five decades over a range of 1.0E-2 to 1.0E5
mR/h. The R45 and R46 monitors operate over a range of 1.0E-2 to 1.0E3 mR/h. Standard features
include a floating decimal point display in mR/h, R/h or kR/h, a multicolor bargraph indicating channel
status and dose rate, front panel pushbuttons for alarm setpoint display, alarm acknowledgement, check
source and AC power. Unpower (dry) 5A relay contacts are provide for Fail, Warn and High radiation
alarms. A powered contact is provided by the Check Source relay. All relays except Check Source are
operated in the normally energized or “fail safe” mode.

The 956A-201-S1 is configured to operate with a 0-10 VDC input processed through the installed model
942-200-75 Analog Input Option circuit board. The 0 –10 VDC input voltage provides 255 steps over the
selected range.

1.4 Rack Chassis 948B-1-5

The 948B-1-5 Rack Chassis is a two channel, 19” width chassis provided with front and rear attachment
points for standard EIA mounting. The physical dimensions of the 948B-1-5 are provided in Appendix A.

1.5 Action Pak S14283A101

The S14283A101 is a factory configured signal converter/isolator powered by 120 VAC. The device
installs in a standard surface mount octal relay socket (provided) and converts a bipolar –10 to +10 VDC
input signal to a 0-10 VDC output. The S14283A101 is the interface between the Simulator’s computer
driven output and the 956A-201-S1 UDR Simulator input.
