The paper considers most elaborated concepts for SNF and HLW disposal in crystalline rocks. It explores in detail an alternative concept suggesting the use of a super-container (SC) with a bentonite buffer located inside a steel body and the SC itself located in vertical wells inside a cement backfill, which is also used to seal fractures crossing the wells.
