Re:
Nine Mile Point Unit 2 Docket No; 50-410-Enclosed for your use are results of preliminary leak testing of the main steam isolation valves for Nine Mile Point Unit 2.
This information is provided to close Safety Evaluation Report open issue 86.
Testing was performed by pressurizing between the ball valve seats, and includes bonnet and stem leakage.
The values should be compared to the acceptance criteria (14 scfh) established in our {{letter dated|date=November 30, 1985|text=letter dated November 30, 1985}}.
