On waste storage, MSRs product much much less waste. A solid fuel, light water reactor achieves maybe 3% fuel efficiency, whereas it's somewhere north of 90% for the thorium MSR. In addition, the byproducts it does produce are mostly useless for nuclear weapons. Dr Carlo Rubbia (former director of CERN and 2016 Nobel Laureate) has stated one of the reasons funding for MSRs was cut by the US in the 70s was precisely because it's difficult to use them to produce nuclear weapons. There are even proposals for MSRs that are fuelled specifically by nuclear waste transuranics (e.g. http://www.transatomicpower.com/wp-content/uploads/2015/04/N...).
Honestly, I'm not so sure the ROI for renewables is anywhere close to 'winning', unless you ignore stuff like renewable intermittancy (meaning you need to build a crapload more highly expensive transmission infrastructure, or attach highly cost-effective batteries to the grid i.e. lead-acid batteries atm).
As for German nuclear, I suppose that won't be a problem once they've completely shut down all their nuclear reactors. Pity that the government official estimated cost of this is 55 billion Euros over the next decade. Although the (frankly more credible) 'unofficial' estimate puts the cost at 250 billion euros over the next decade. Not to mention the fact it's resulted in their co2 emissions increasing in both 2015 and 2016 (https://www.cleanenergywire.org/factsheets/germanys-greenhou...). Their own environment ministry now predicts they will probably not make their 2020 co2 reductions targets.
So other than the enormous cost and increase in co2 emissions, good policy.
