NUCLEAR WASTE
One major problem for nuclear power is the waste it (25) ______. A typical nuclear reactor needs to get rid of 20 tons of spent fuel per year. The radioactivity in this waste takes 1000 years to diminish to negligible levels other dangerous contents include longer-lived fission products and uranium and plutonium, the 239 isotope of (26) _____ takes more than 150,000 years to decay to negligible amounts. It is important to keep this material away from people. To that end, the spent fuel initially goes into a pool at the reactor, (27) _____ it is kept beneath 5 metres of cooling water that blocks its radiation. After some years, the fuel can be removed and put into dry cask storage which, as the phrase (28) _____, means it is put in big drums at the plant. Two such casks can hold one year's spent fuel safely for 100 years. After that, the casks should ideally be put into a mined geological repository - entombed in deep underground tunnels in a geologically stable (29) _____.

Kiến thức: Từ vựng
Giải thích:
A. shows (v): chỉ ra, cho thấy B. states (v): phát biểu, tuyên bố
C. presents (v): trình bày, đưa ra D. suggests (v): gợi ý, đề nghị
=> as the phrase states: như chính cụm từ đó nói (ý nói: cái từ đã nói lên ý nghĩa)
(phrase = put into dry cask storage)
After some years, the fuel can be removed and put into dry cask storage which, as the phrase (28) states, means it is put in big drums at the plant.
Tạm dịch: Sau một vài năm, nhiên liệu có thể được lấy ra và đưa vào kho chứa trong thùng khô, như đã nói, điều đó có nghĩa là nhiên liệu được bỏ vào các thùng phuy lớn tại nhà máy.
