Some More News
• SmartCAM AB+ passed seismic testing
• The Testing was carried out at the Earthquake Engineering
Laboratory at Bristol University.
• Used a tri-axial vibratory shaker table testing, in accordance
with IEEE Std 344-2004, IEEEE Recommended Practice for
Seismic Qualification of Class 1E Equipment for Nuclear
Power Generating Stations. Testing was carried out in three
mutually perpendicular test axes in accordance with IEEE Std
344-2004, Para 8.1.5.2

Alarm and Data Management System –
9205EMS
• 9205 – Generic Network Software Package
• Supports multiple communications
protocols
• Real Time Display of Measured Values
• Generates and Logs Alarms
• Accumulates Stack Discharge (Daily,
Weekly, Monthly, Annual)
• Database of results (History)
• Automated Reports in Word format
Stack Flow Measurement
• Pitot tube averages flow across duct
– Stainless steel
– Proper placement important
• DP-2001 Differential Pressure
– Calibrated for correct pressure range
• 4 to 20 mA Signal to CMS-Pet
– Standard Ethernet cable used
Stack Sampling Systems
•
•
•
•
•
•
Shrouded probes (1” and 1.5”)
Meet ANSI N13.1-1999
Licensed by Texas A&M
NQA-1 Quality Assurance
Seismic analysis performed
Design capability for new
applications
• Gas sampling probes
• Various mounting flanges used
System Use With Air Cannons
• Flow rates cannot be accurately measured after the air
cannon because of turbulence
• Measuring the concentration prior to the air cannon offers
better statistics for lower concentrations
• Software can add in the additional air allowing it to report
proper release concentration results
• Monitoring before the air cannon allows proper
measurement and reporting of activity releases
