However, short-term heat emission, one deep geological repository limiting factor, is predominantly from medium-lived fission products, particularly 90 Sr ( 28.9 year half life ).

The search for a suitable site for a deep geological repository commenced shortly after the commissioning of the first nuclear units at the Dukovany nuclear power plant, i . e . in the 1980s.
33.
It is generally accepted that the final waste will be disposed of in a deep geological repository, and many countries have developed plans for such a site, including France, Japan, and the United States.
34.
It would also provide $ 20 million for collaborative research into devising reactors and fuel that cannot be used to make weapons, and $ 5 million for research into the design and development of a permanent geological repository to store used fuel.

The "'Asse II mine "'( "'Schacht Asse II "') is a former salt mine used as a deep geological repository for radioactive waste in the Wolfenb�ttel, Lower Saxony, Germany.
36.
SOGIN signed a similar agreement with the Radioactive Waste Repository Authority ( RAWRA ) in the Czech republic in 2016 covering the storage of nuclear waste, including collaboration on a deep geological repository for spent nuclear fuel and high-level waste.
37.
As an alternative to uranium fuelled nuclear reactors, thorium has been proven to add to proliferation, produces radioactive waste for deep geological repositories like technetium-99 ( half-life over 200, 000 years ), and has a longer fuel cycle.
38.
Makhijani has studied the French reprocessing and nuclear energy system and was the director of a team that analyzed ANDRA s plans for a geological repository for high level radioactive waste in France on behalf of a French government-sponsored stakeholder committee ( 2004 ).
39.
The key technical element of the approach is the ultimate centralized containment and isolation of the used fuel and other high level waste in a deep geological repository in a suitable rock formation, such as the crystalline rock of the Canadian Shield or Ordovician sedimentary rock.
40.
The "'Yucca Mountain Nuclear Waste Repository "', as designated by the Nuclear Waste Policy Act amendments of 1987, is to be a deep geological repository storage facility for spent nuclear fuel and other high level radioactive waste in the United States.
