TOKYO, Oct 10 (Reuters) - Kansai Electric Power  9503.T 
will shut the 826 megawatt (MW) No.3 reactor at its Mihama
nuclear power station in western Japan after discovering two
small holes in a pipeline, the company said on Thursday, without
specifying the timing of the action.
    The holes were found in a pipe used to release water from
the cooling system to the sea and the shutdown is aimed at
investigating the cause of the problem, the company said in a
statement.
    "No decision has been made on the timing of the shutdown as
specific processes are being discussed," a company spokesperson
said.
    Separately, Shikoku Electric Power  9507.T  shut the 890-MW
No. 3 reactor in western Japan on Oct. 7 due to a malfunction in
the equipment used to monitor fuel combustion, a company
spokesperson said, adding no date has been set for the
resumption of operations.
    The utility has restated the reactor on Sept. 29 following
planned maintenance which started on July 19.
    As of Thursday, Japan has 11 operating reactors with a total
capacity of 10,718 MW.
    Many companies are still going through a re-licensing
process to comply with stricter safety standards imposed after
the 2011 Fukushima disaster. The companies had 54 operational
reactors before it.
