A process plant shutdown system is a functional safety countermeasure crucial in any hazardous process plant such as oil and gas production plants and oil refineries. The concept also applies to non-process facilities such as nuclear plants. These systems are used to protect people, assets, and the environment when process conditions get out of ...
Fresh meat and other refrigerated food could spoil, resulting in shortages and increased prices. "I think everyone's a bit nervous about it," said Mia Ginter, director of North America ocean ...
A blowdown valve (BDV) is a type of shutdown valve designed to depressurize a pressure vessel by directing vapour to a flare, vent or blowdown stack in an emergency. BDVs fail-safe to the open position upon failure of the control system. [1] The type of valve, type of actuation and performance measurement are similar to an ESD valve.
During the shutdown, the federal government's e-Verify system—a system for employers to check the eligibility of their employees to work in the United States—was halted. [232] [233] During the shutdown, a wave of Domain Name System (DNS) attacks on government sites was detected by Homeland Security. The attacks were serious because these ...
The impact will be swift. With less than two weeks until a partial government shutdown, the House of Representatives is expected to vote on a bill today that combines a must-pass spending bill ...
Black start. Toronto during the Northeast blackout of 2003, which required black-starting of generating stations. A black start is the process of restoring an electric power station, a part of an electric grid or an industrial plant, to operation without relying on the external electric power transmission network to recover from a total or ...
Output signal switching device. An output signal switching device (OSSD) is an electronic device used as part of the safety system of a machine. It provides a coded signal which, when interrupted due to a safety event, signals the machine to shut down. It works by converting the standard direct current supply, usually 24 volts, into two pulsed ...
Reactor protection system (RPS) A reactor protection system is designed to immediately terminate the nuclear reaction. By breaking the nuclear chain reaction, the source of heat is eliminated. Other systems can then be used to remove decay heat from the core. All nuclear plants have some form of reactor protection system.
