United Utilities Renewable Energy (UURE) owns and operates upwards of 60 renewable technology assets across the North West of England, including solar photovoltaic, hydro and wind turbines. Many of the solar photovoltaic (PV) systems are mounted on the ground, meaning management of nearby organic growth is an important part of the overall Operations & Maintenance strategy and is key to ensuring the safe and efficient on-going output of the system.
Determining the density of graphite bricks
The reactor cores of Advanced Gas-cooled Reactors (AGRs) in the UK are made up of graphite bricks. Channels run through these bricks, containing nuclear fuel, control rods and other equipment. Control rods are used to control and to shut down the nuclear reactor. Over time, the properties of the graphite bricks are modified, and these changes can contribute to determining how long a reactor can operate. One way in which the bricks change is in their density. The challenger is seeking solutions which will enable them to measure this density change over time.
