The crack is located in the heat affected zone of the weld where the four (4) inch line is joined to the 24 inch ' A' LPCI line.
The leak is isolable from the Reactor Coolant system.
The plant was in a shutdown condition with the ' A' Residual Heat Removal (RHR) shutdown cooling system in operation.
Licensee personnel observed water in the general area and removed the piping insulation on March 20, 1979.
At that time water was observed spraying from the crack.
The 'A' RHR system was secured and tagged out and the 'B' RHR system placed in operation.
No radiological problems have been encountered.
The crack has been observed as approximately a four (4) inch long hairline crack.
The licensee is performing an engineering evaluation to determine the best method of repair.
Media interest is possible because of the past pipe crack concerns.
