## Description
JET Decommissioning and Repurposing
J5 Reactive Power Compensation Compound:
The J5 Reactive Power Compensation (RPC) compound, is a legacy facility located in the northern area of the Culham Science Campus. Operating from early 1990s to 2012 the purpose of the J5 RPC system (external compound and internal network) was to avoid causing disturbances to the 400kV National Grid supply as a result of large power pulses on site.
The RPC compound has been left in a quiescent state since it was disconnected from the Joint European Torus power supplies and mothballed.
The J5 RPC compound contains high voltage, low voltage, and extra low voltage electrical equipment including resistors, capacitors (624 high voltage oil filled capacitors to be exact), inductors, and surge arresters along with cable and busbar systems.
Please refer to attached documents for further details.
