g gon February 9, 1982, a steam generator tube leak of approximately 0.11 GPM was ;

indicated by the Condensate Steam Air Ejector Of fgas Radiation Monitor. This

, , , constitutes an abnormal degradation of the reactor coolant pressure boundary and, g l1s reportable pursuant to Technical Specification 6.6.2.1.a(3). Personnel and g systems adequately controlled this event and the releases were well within reg-

g gThe apparent cause of the < team generator tube leak was a crack on Tube 74-2. I g lThis unit was shut down and cooled down. The leakinn tube was stabilized from i g.the top and was explosively plugged from the bottom. Eddy current testing in ,

'the lane region showed no tubes unacceptably degraded.
