Depressurization to Mitigate Direct Containment Heating
Nuclear Technology, 1989This paper reports the capability to depressurize a three-loop pressurized water reactor during a station blackout sequence assessed using the SCDAP/RELAP5 computer code. During the initial calculations, failure of the pressurizer surge line from creep rupture was predicted prior to relocation of molten core material to the lower plenum.

Introducing a Depressurization Step in Online LCxSFC Modulation
Analytical ChemistryNew online LCxSFC valve technologies have recently been developed, based on the transfer of the first-dimension eluent either in the CO2 stream or in the cosolvent stream of the SFC dimension. While using the appropriate valve configuration greatly improved peak shapes, the reduction of the analysis time remained a challenge.

Volume 9: Advanced Methods of Manufacturing for Nuclear Reactors and Components; Severe Accidents and Mitigation Strategies for Beyond Design Basis Events
Abstract In this paper, based on the system analysis program, the AP1000 nuclear power plant is taken as the research object, and the AP1000 system analysis model is built. Taking the DVI pipeline break accident as the starting event, the depressurization strategy of the ADS is studied.

Effects of Depressurization Upon Largemouth Bass
North American Journal of Fisheries Management, 1983Abstract The effects of induced, rapid depressurization upon largemouth bass (Micropterus salmoides), simulating conditions common to deep-water angling, were examined. Depths of 0.0, 9.1, 18.3, and 27.4 m were simulated in a large hyperbaric chamber. Statistical analyses indicated that significant mortality occurred when fish were depressurized from ...

EXTINGUISHMENT OF SOLID PROPELLANTS BY RAPID DEPRESSURIZATION
1969Abstract : A new theory for extinction by depressurization of AP composite propellants is employed to predict the rate of pressure decrease required to achieve flame-out and to rationalize the effects of various composition parameters on the ease of extinguishment.

PROBABILITY OF EMERGENCY RELEASE DURING DEPRESSURIZATION
"The idea of the proposed work is that the volume of an emergency discharge should be calculated based on the characteristics of the discharge event itself." There are some tools for this that are not used by developers of analysis methods. This refers to an automatic method of monitoring emissions using sensors up to an explosive gas concentration ...Qazanfar Suleymanov +3 more

A simplified model of the BWR depressurization transient
Nuclear Engineering and Design, 2001A simplified model is proposed to evaluate the BWR plant depressurization transient subsequent to the activation of a single safety relief valve. The model is validated with a series of RELAP5 Mod 3 calculations yielding reasonable comparisons. The depressurization behavior of the 26 US BWR plants is analyzed with the model and the relevant parameters ...
