Security and Risk Mitigation – Practical and Cost-Effective Solutions by the U.S. Nuclear Industry

April 3, 2016

by Gary Hayner, Manager – Safety and Reliability Introduction The highly regulated United States nuclear industry must balance safety, performance, and cost.  Safety to the public, competition with other energy producing industries, and the large capital and O&M costs of nuclear are exaggerated compared to other industries.  Among these clashing constraints is the intersection of plant

Before The Alarm Sounds

March 17, 2016

Published in Canadian Property Management: GTA & Beyond magazine   By Steven Strege, PE Fire, egress models allow building design to move beyond applicable code requirements With the advancement of computers, mathematical models have emerged to aid engineers and architects in the design of safe buildings. A prime example of this is in the area of fire

Computational Modeling and Validation of Aerosol Deposition in Ventilation Ducts

March 17, 2016

Published in Fire Technology January 2016 edition By Kristopher Overholt, Jason Floyd, Ofodike Ezekoy Abstract. In fire models, the accurate prediction of aerosol and soot concentrations in the gas phase and their deposition thicknesses in the condensed phase is important for a wide range of applications, including human egress calculations, heat transfer in compartment fires,

Robotics in Firefighting and Disaster Response

January 22, 2016

Brian Lattimer PhD, Vice President of R&D at JENSEN HUGHES, is leading a project focused on developing technology for robotic firefighting, which is being incorporated onto a humanoid robot at Virginia Tech. The effort was featured in a recent article in Unmanned Systems magazine describing firefighting robots. JENSEN HUGHES with Virginia Tech is developing new

Development and Analysis of Electrical Receptacle Fires

September 12, 2013

Laboratory testing evaluated the impact of a wide range of variables on the formation of overheating connections in residential duplex receptacles. Two types of receptacle configurations have been evaluated: 1) those focused on terminal connections and 2) those focused on plug connections. Testing included 528 receptacle trials, 408 trials with various terminal connections and 120

Sprinkler Protection for Cloud Ceilings

July 1, 2013

Cloud ceilings are ceiling panels that sit beneath the structural ceiling of a room or space and are seen increasingly in commercial and industrial buildings.  “Cloud” panels range in area from discrete ceiling panels with large spaces in between, to close-to-full-room-area contiguous coverage with small gaps at the perimeter wall location. NFPA 13, Standard for
