A process for compacting radioactive waste by precompressing the waste in each of capsules while filling the waste into the capsule to thereby compress the waste to the desired bulk/true density ratio under a small total pressing load and diminish damage to the inner surface of the die used, each of the capsules having a cross sectional form corresponding to a divided segment of the cross section of an HIP treatment container, then placing the capsules into the HIP treatment container, subsequently filling the HIP treatment container with a metal powder as a filler, thereafter degassing and sealing the HIP treatment container and subjecting the container to an HIP treatment in its entirety. The process precludes scattering of the radioactive substance from the waste and release of waste fragments to assure improved safety.
