Abstract: Provided in the present disclosure are an encapsulation adhesive film and a photovoltaic module. The encapsulation adhesive film includes an infrared high-transmittance adhesive film layer, and an infrared high-reflection adhesive film layer, which is stacked on the infrared high-transmittance adhesive film layer. The light transmittance of the infrared high-transmittance adhesive film layer for light within a wavelength range of 700-1100 nm is greater than 55%; the light transmittance of the infrared high-transmittance adhesive film layer for light within a wavelength range of 400-700 nm is less than 2%; and the reflectivity of the infrared high-reflection adhesive film layer for the light within the wavelength range of 700-1100 nm is greater than 75%. By using the encapsulation adhesive film as an encapsulation adhesive film on a back side of a cell piece, black exterior appearance of the photovoltaic module can be realized so as to reduce light pollution.

Abstract: Method for installing reactor coolant loop (RCL) piping of a reactor coolant system (RCS) system in a pressurized water reactor (PWR) nuclear power plant by positioning the reactor vessel, steam generator, or both, into position after attaching one or more coolant pumps, surveying coolant loop piping and a plurality of nozzles on the reactor vessel, the steam generator and coolant pump casing, or a combination thereof, with a precise measurement and 3D modeling technology for positioning data, then performing weld prep machining for the coolant loop piping on the reactor vessel side, and machining for the coolant loop piping on the steam generator side and coolant pump side based on the positioning data, and installing temporary supports for coolant loop piping and finishing the fit-up and welding between the coolant loop piping and the reactor vessel, steam generator, and each coolant pump.
