It's 28317 cubic metres or 500 residential swimming pools, 4 by 7 by 2 metres. By contrast 250000 cubic metres of concrete went into OL3[1]. This is also low level waste such as Fukushima rubble. For reference the UK has LLW in storage amounting to 14700 cubic metres or 17800 tonnes by mass, with an activity of 11 terabecquerels. These are the estimates for decomissioning of all the Olkiluoto reactors[2]: "The amount of decommissioning waste is around 32 000 m3, generated from Olkiluoto 1 and 2 mainly during 2068-2076. The amount of Olkiluoto 3 decommissioning waste is estimated to be around 11000 m3 before packing and generated during 2079-2085. Additionally there will be approximately 2000 m3 of waste from the spent fuel interim storage decommissioning to be generated around 2100." 1. https://www.tvo.fi/uploads/File/2009/OL3_Basic_Facts_2009.pdf 2. https://ec.europa.eu/energy/sites/ener/files/fi_2nd_nr.pdf
