Pravdinskoye Oil Field
Pravdinskoye Oil Field (Правдинское месторождение) is a large oil field in the Khanty-Mansi Autonomous Area of Western Siberia, Russia, discovered in 1964 and producing since 1968.
Pre-lithiation
Pre-lithiation is a battery manufacturing technique that adds extra active lithium to a lithium-ion cell, compensating for lithium irreversibly lost during the first charge and early cycling.
Precursor cathode active material
Precursor cathode active material (pCAM) is a mixed nickel-cobalt-manganese hydroxide intermediate from which lithium-ion battery cathode powder is made by lithiation and calcination; it is produced almost entirely by co-precipitation.
Predictive current control
Predictive current control (PCC) is a power electronics control method that predicts the load current for each candidate switching state and applies the one minimizing the predicted error.
Preem
Preem is a Swedish fuel company that refines and sells gasoline, diesel, and renewable fuels at its Lysekil and Gothenburg refineries. Founded in 1996, it is Sweden's largest fuel producer.
PRefChem
PRefChem (Pengerang Refining and Petrochemical) is the name for two joint ventures of PETRONAS and Saudi Aramco operating a 300,000-barrel-per-day refinery and petrochemical complex in Pengerang, Johor, Malaysia, started up in 2019.
Prelude FLNG
Prelude FLNG, also known as Shell Prelude, is a Shell-operated floating liquefied natural gas facility off Western Australia, the largest floating offshore facility ever built.
Premier Transmission
Premier Transmission Limited is a Northern Ireland gas transmission company that owns the Scotland to Northern Ireland Pipeline, a 135-kilometer link from Twynholm, Scotland, to Ballylumford.
Premixed combustion
Premixed combustion is combustion in which the fuel and oxidizer are mixed before burning, so a flame propagates through a homogeneous mixture, as in a Bunsen burner.
Presidente Juárez power station
The Presidente Juárez power station, also known as the Rosarito complex, is a gas-fired power station at Playas de Rosarito, Baja California, owned by CFE.
Presidente Médici Candiota power station
The Presidente Médici Candiota power station, also called Candiota II, is a coal-fired power station in Candiota, Rio Grande do Sul, Brazil, built between 1974 and 2011.
Pressure suppression pool
A pressure suppression pool is a pool of water inside a boiling water reactor's containment that condenses steam released during an accident, limiting containment pressure.
Pressure transient analysis
Pressure transient analysis (PTA) is a well testing method that interprets pressure changes measured in a well over time to estimate permeability, skin factor, and reservoir pressure.
Pressurized fluidized bed combustion
Pressurized fluidized bed combustion (PFBC) is a coal-fired power technology in which coal burns under pressure in a combined steam and gas turbine cycle, commercialized in the 1990s.
Pressurized thermal shock
Pressurized thermal shock (PTS) is a pressurized water reactor event combining severe overcooling of the reactor pressure vessel with high pressure, threatening vessels embrittled by neutron irradiation.
Pressurized water reactor
A pressurized water reactor (PWR) is a nuclear reactor in which water held at high pressure serves as coolant and moderator, the most common reactor type worldwide at about 65% of operating power reactors.
Pressurizer
A pressurizer is a tank, roughly half filled with water and half with steam, that controls pressure in a pressurized water reactor using electric heaters and a cool-water spray.
Price of oil
The price of oil is the market price of crude oil, quoted in U.S. dollars per barrel and tracked through benchmarks such as Brent, WTI, and Dubai/Oman.
Price-Anderson Act
The Price-Anderson Act, a United States federal law enacted in 1957, governs liability for nuclear accidents, requiring private insurance backed by an industry-funded secondary layer of about $16.1 billion.
Priest Rapids Dam
Priest Rapids Dam is a run-of-the-river hydroelectric dam on the Columbia River in central Washington, owned by Grant County PUD No. 2 and completed in 1961.
Primary frequency response
Primary frequency response is the rapid, automatic action of grid generators to arrest and stabilize frequency deviations within seconds, until secondary control restores normal frequency.
