English term

covering

English Science Nuclear Eng/Sci
Unlike in Units 1, 3 and 4, the Unit 2 reactor building was still covering the Unit 2 spent fuel pool, and consequently the spray method for replenishing pool water could not be used for Unit 2.

Units refer to nuclear units.
Spent fuel pools are pools to store spent fuels.

had roof on

Unit 2 reactor building had not had its roof blown away by hydrogen explosion, so the roof did prevent spraying water into the pool from above

This assumes that you are still working oin the Fukushima Daichi accident, see this report describing the helicopters used to drop water onto the spent fuel pools of buildings 3 and 4, with "building housing reactor No. 2 was "slightly damaged"":
