LICENSEE'S TESTIMONY OF GARY R. CAPODANNO IN RESPONSE TO ALAB-708 ISSUE NO. 1 (HOT LEG HIGH POINT VENT SIZING) l 8302220359 830216 PDR ADOCK 0500028 T

SUMMARY

This testimony is in response to the Appeal Board's request for_information concerning the sizing and flow rates of the hot leg high point vents to be installed at TMI-1. In

-accordance with the guidance of NUREG-0737, the vents have been sized such that system failure would not constitute a loss of coolant accident. The system is capable of relieving 7.6 pounds per second of subcooled water at 2500 psig and 600 F.

1 INTRODUCTION 2

This testimony, by Gary R. Capodanno, GPU Nuclear Fluid 3

Systems Director, is addressed to Issue No. 1 of the' Appeal 4

Board's Memorandum and Order of December 29, 1982 (ALAB-708),

5 which requests the following information:

6

1. The exact size and flow rate of the 7

vents to be installed in the hot legs (fron the licensee).

8 g BY WITNESS CAPODANNO:

10 The vent flow path from each hot leg consists of nominal 11 half-inch diameter piping, two solenoid-operated valves, one 12 manually- Perated valve and a flow-detecting orifice. The P ii P ng has an internal diameter of 0.464 inches and an outside 13 g diameter of 0.840 inches. The solenoid valves have a minimum 15 internal diameter of 0.464 inches and the manual valve has a p

mnmm n erna ame er f . n es. e Pening l 16 g is 0.371 inches in diameter.

i g The vent path is sized such that it will pass 7.6 pounds g per second of subcooled water at design conditions of 2500 psig a d 600 F; the sizing follows the guidance in NUREG-0737 and 0

ensures that failure of the vent line would not result in a loss-of-ccolant accident as defined in Appendix A to 10 C.F.R. Part 50. The attached figure, "TMI-1 Hot Leg Vent Capability",

shows the capability of the vents to remove saturated steam at different reactor coolant system pressures.
