Arsenal Extended Power License Generator

During an extended power uprate test on March 5, 2002 (designed to extend the power efficiency of existing BWR reactors), Quad Cities Unit 2 began to experience vibrations in a steam line. On March 29 the plant was manually shut down due to high vibrations causing leaks in the main turbine control system. Unit 2 was restarted on April 2, but vibration broke a main steam pipe drain line. The line was repaired and the restart resumed, but by June 7 the main steam lines were showing unexplained aberrations. The plant was again taken offline for repairs on July 11, and the problem was traced to a hole in the steam dryer. The steam dryer was repaired and Unit 2 was restarted on July 21, 2002. The incident did not result in any increased probability of an accident. The NRC inspected all repairs and the extended power uprate was completed successfully.[6]

MW: Megawatt. The international unit of power that is equal to 1x106 watts. A megawatt electric (MWe) refers to the electrical output from a generator. A megawatt thermal (MWth) refers to the heat output from a nuclear reactor. The difference is a measure of the efficiency of the power generation process. Typically, the heat output of a nuclear reactor is three times its electrical output, thus a reactor with a thermal output of 2 700 MW may produce about 900 MW of electricity.

In December 2018 Rosatom told the company that first power would be in 2028 due to delays in documentation with STUK, and construction start was likely in 2021. In October 2019 Japan Steel Works' Muroran plant started forging the generator rotor for the plant, under contract to RAOS Project, a Rosatom subsidiary. It will then be sent to the GE Steam Power facility in Belfort, France, to be machined. The 240-tonne rotor will be 8 metres long and 2 metres wide.

Microwave wireless power transmission technology has broad application prospects in improving the endurance and range of unmanned equipment. It is also of great significance in the field of the Internet of things, which can effectively solve the problem of energy supply for devices in the Internet of things. In addition, using vehicle-mounted microwave wireless power transmission to power multi-objective unmanned aerial vehicle swarms and to build an air-ground integrated power transmission network. In this study, the corresponding technical index system and test evaluation methods, which are conducive to promoting the development and progress of this technology, were established. The topology of a microwave wireless power transmission system was analyzed, and technical evaluation indices were developed for microwave wireless power transmission systems, signal generators, power amplifiers, transceiver antennas, and rectifier circuits. Test evaluation methods were established consisting of test equipment, methods, and processes to provide powerful technical means for the development of microwave wireless power transmission systems.

The basic topology of the microwave wireless power transmission system is shown schematically in Fig. 2, which depicts the DC energy source, microwave power generator (microwave signal generator and power amplifier), transmitting antenna, free space, rectifying antenna (receiving antenna and rectifying circuit), and DC load [11, 12].

The DC energy source provides energy for the microwave power transmission system. The signal generator is used to generate low-power microwave signals, and the power amplifier amplifies the generated small signals to output high-power microwave signals. The transmitting antenna converts the fed high-power microwave energy into electromagnetic waves that radiate into free space. The receiving antenna converts the electromagnetic wave of the corresponding frequency band in the area into a microwave signal in the circuit and sends it to the rectifier circuit. The receiving antenna and rectifier circuit are often combined into a rectifier antenna. The microwave rectifier circuit uses the nonlinear effect of the rectifier diode to convert the received radiofrequency energy into direct current energy (RF-DC) to power the load.

The main equipment used for the performance test of the signal generator comprised a DC energy source, spectrum analyzer, and DC power meter. The spectrum analyzer is the basic tool for observing the signal. It can locate and measure the frequency of the signal and display it graphically. The test diagram is shown in Fig. 3.

Step 4 Use the marker function of the spectrum analyzer to find the maximum power point, which is the output power of the signal generator, and record the frequency \(f_s\) corresponding to the point, which is the working frequency of the signal generator.

where \(\eta _s\) is the efficiency of the signal generator, \(P_\mathrmsin\) is the DC input power of the signal generator (W), and \(P_\mathrmsout\) is the output power of the signal generator (dBm).

Microwave wireless power transmission system is mainly composed of signal generator, power amplifier, transceiver antenna, rectifier circuit and other key components. This paper adopts the idea of splitting and reorganization, analyzes the functions of each component in the microwave wireless power transmission system, puts forward the indicators that may affect the transmission efficiency of the system, and then puts the components as the tested object into the microwave wireless power transmission system for testing, so as to form a perfect microwave wireless power transmission technology index system and test and evaluation method. It can not only evaluate the performance of a single component, but also evaluate the impact of components on the system performance and the actual application performance of the system, so as to provide a reference basis for the development of microwave wireless power transmission technology.

Signal generator, power amplifier, transceiver antenna, and other technologies should be studied to improve the conversion efficiency of the core components further and strengthen the miniaturization, lightness, assignability, electromagnetic compatibility, and other types of performance of microwave wireless energy transmission systems.

Available in regular cab, extended cab (SuperCab), and crew cab (SuperCrew) configurations, the 2022 Ford F-150 is America's best-selling full-size light-duty pickup truck. Following a 2021 redesign and the arrival of the new 2022 F-150 Lightning, it is also arguably the most technologically sophisticated truck available today, with the most diverse model range and powertrain menu. So if you can't find a 2022 Ford F-150 that meets your needs, you're not looking hard enough.

The big news, however, is the arrival of the 2022 F-150 Lightning electric truck. The dual-motor EV comes with a standard- or extended-range battery pack and offers between 230 miles and 320 miles of estimated driving range. Ford says it targets an output of 563 horsepower and 775 pound-feet of torque, a 2,000-pound payload capacity, and 10,000 lbs. of towing capacity. Acceleration to 60 mph will take about 4.5 seconds.

The Raptor came with the 2.0-kW Pro-Power Onboard system. It exports that amount of electrical power from the engine via 120-volt outlets mounted on the inner left wall of the bed. The Lightning offers a more robust 9.6-kWh onboard generator, and the EV exports power via 120-volt outlets in its Mega Power Frunk and 120- and 240-volt outlets in its cargo bed.
