Work to reinforce No.4 reactor building to begin, NHK, May 23, 2011:
Work is beginning on Monday at the Fukushima Daiichi nuclear plant to reinforce the structure supporting the No.4 reactor’s spent fuel pool.
Tokyo Electric Power Company, the plant’s operator, says the work is necessary to install a cooling system for the stored spent fuel. [...]
TEPCO’s plan calls for building a new concrete structure under the pool to prevent its bottom from falling out. [...]
TEPCO says it hopes to erect the columns next month and complete the reinforcement by the end of July. [...]
