Nuclear Waste in Sweden - The KBS-3 Method is Not a Solution 
There is a general consensus that there are many uncertainties.
In Sweden, since the mid-1970s, the nuclear industry has put forward the KBS method of handling spent fuel. According to SKB, the total estimated planned quantity of spent fuel is 11,404 tonnes.F Now in 2019, more than 40 years after the KBS project began, there is a general consensus among all stakeholders, with few exceptions, that there are many uncertainties. There is however a wide range of views among this diverse group about the severity of the uncertainties and how to deal with them. This is particularly evident when comparing the results of the reviews by the Land and Environment Court (MMD) and the Swedish Radiation Safety Authority (SSM). Some main results of their reviews are given below.
Result of the Review by SSM: Yes, Providing Certain Conditions are Met
SSM wrote in their 23 January 2018 statement to the government that they approve SKB’s application provided certain conditions are met. Following is a quote from the statement (emphasis added).
SKB may commence construction of the facility
only after SSM has examined and approved a
Pre-construction Safety Analysis Report (PSAR). 
With regard to the copper corrosion issue SSM wrote in the same statement that the issue might be resolved in the future (emphasis added).
According to SSM there is potential to achieve
an acceptable corrosion barrier with a 50 mm thick
copper casing (p. 66).
Result of the Review by the Court: No, Unless Certain Conditions are Met
MMD wrote in their press release regarding their 23 January 2018 statement to the government:
The court cannot, based on the current safety
assessment, find that the final repository is
safe in the long-term. 
The overall result of the Land and Environment Court (MMD) review was that the industry application should not be permitted unless specific uncertainties are resolved. The court wrote the following on page one of its 23 January 2018 statement and summary statement.
The activity is permissible if:1. The Swedish Nuclear Fuel and Waste Management Co.
provides documentation that the final repository will
meet the requirements of the Environmental Code in the
long term, despite remaining uncertainties regarding how
the protective capability of the canister is affected by: a. corrosion due to reactions in oxygen-free water b. pit corrosion due to reaction with sulphide,
including the contribution of the sauna effect to
pit corrosion c. stress corrosion due to reaction with sulphide,
including the contribution of the sauna effect to
stress corrosion d. hydrogen embrittlement e. radioactive radiation impact on pit corrosion,
stress corrosion and hydrogen embrittlement.2. The long-term responsibility for the final repository
according to the Environmental Code has been clarified. 
Regarding various uncertainties, following are more quotes from the court’s statement.
Risk of copper corrosion (emphasis added):
The investigation shows that there are uncertainties,
or risks, regarding how much certain forms of corrosion
and other processes can impair the ability of the canister
to contain the nuclear waste in the long term. Overall,
these uncertainties about the canister are significant and
have not been fully taken into account in the conclusions
of SKB's safety analysis (p. 4).
Radiation safety (emphasis added):
SKB and SSM have expressed the view that conditions
relating to radiation safety should not be prescribed
in a permit under the Environmental Code. The Court finds
that the evidence presented to date does not provide a
sufficient basis on which to assess the issue (p. 11).
Risk in general (emphasis added):
...a new calculated result of the entire safety
assessment is required...(p. 10).
Uncertainties in general concerning the repository, radiation safety, and the geologic conditions (emphasis added):
The Court however emphasizes that the study of the
bedrock formation at Forsmark, for example, leaves
ambiguities that may justify a probationary period
for evaluation for the determination of conditions
regarding respect distances or other precautionary
measures (p. 14).
