The paragraph above this table:

As of 30 November 2014, 131 900 m3 of debris and 79 700 m3 of trees were being stored on-site. The amounts of trees and debris being stored on-site in temporary storage facilities are provided in Table 5.4–5, together with the fraction of the quantity of waste in storage relative to the current estimated capacity for each of the storage facilities. It is conservatively estimated that a total of 560 000 m3 of contaminated material will be generated by the end of the fuel debris removal, which is planned for 2027. A new centralized storage facility is being planned with a capacity of approximately 160 000 m3. The difference between the expected amount of waste and the planned capacity of the storage facility highlights the expectation that waste segregation, volume reduction, and recycling will reduce the volume of waste requiring long term management (storage) as radioactive waste.

Explanation:
At the bottom of page 107 of the document:

5.4.3.4. Waste management during the emergency phase

The materials generated during the early remediation of land, buildings, agricultural land, forests, dams, and so on, were temporarily stored at designated places. Contaminated materials were packed in weatherproof sandbags or waterproof bags and placed on plastic sheets on the ground. The collection was then covered with plastic sheets, and sandbags were placed on the plastic sheet to provide radiation shielding. Contaminated disaster waste, in particular, was segregated by dose rate.
Enhanced shielding measures were also taken to reduce dose rates [176]. A wide range of focused remediation projects were rapidly initiated by municipalities and local communities during the emergency phase for specific areas (schools, playgrounds, public land, trees/forests, roof surfaces and gutters, drainage systems, roads, etc.).

The reference above mentions moisture retaining covers used for curing.

I'm trying to find an explanation of the sheet curing process. It entails covering the rubble with a sheet, with or without a curing agent.

Curing
allowing partially composted materials to sit in a pile for a specified period of time as part of the maturing process in composting.

But in this case, the rubble is covered by a sheet.

Yes, I am quite sure. I have only given my answer a confidence level of 3 because I haven't been able to find any references in which the sheet curing process is explained. All the documents I've found are over 500 pages long and I don't have time to read through all of them.

Hopefully someone will be able to confirm I'm right or suggest an alternative solution, although I'm sure the rubble is covered with sheets. What I don't know is the material the sheets are made of, or whether a curing agent is added to the rubble.

Asker: I have already translated that page but I do not know if this is the same!

Asker: Thanks for your time. So, is this your final conclusion: the rubble is covered by a sheet?

agree  Port City: They covered radioactive rubble with waterproof sheets such as tarpaulins (without a curing agent).
