Drawing Continuation Responses 2.3.4.5 Drawing LR-39222 and LR-39223 RAI: Location B-5, show a continuation of incoming pipe sections (with no identification numbers [Condensate Transfer]) from drawing LR-39220 NSPM Response: The continuation of drawings LR-39222 and LR-39223, location B-5, Condensate Transfer to line 8-DE-56, is shown on LR-39220, location E-2, 2 1/2 Condensate Transfer and Recycle Pump discharge lines connecting to line 8-DE-56 on either side of valve C-41-2.

3/4 Issue: The continuations are located at E-2 however the scoping criterion of pipe sections (out of system dashed lines) dont match. the feed lines (from unit 2 condensate storage tank) on LR-39222 are 10 CFR 54.4 (a) (1) lines to which these (a) (2) lines are connected (B-5). Additional information needed is the location of anchors on drawing (LR-39220, B-5)downstream of valves C-34-2 and C-40-3.

2.3.4.6 Drawings LR-39218 and LR-39219 RAI: Drawing LR-39218, locations F-6, G-5, and G-6, pipe sections 10-MS-27, 12-MS-3, 12-MS-4, respectively, continuations to drawing LR-39233 NSPM Response: The continuation of LR-39218, locations F-6, G-5 and G-6, lines 10-MS-27, 12-MS-3 and 12-MS-4, are shown on LR-39233, location F-1, at valve TD-4-2 (line 10-MS-27) and location B-3, at valves TD-10-1 and TD-10-5 (lines 12-MS-3 and 12-MS-4).

3/4 Issue: The continuation lines were located; however please confirm the scoping criteria for the out of system dashed lines (10) before valve TD-4-2 in drawing LR-39233.

RAI: Drawing LR-39218, location D-7, pipe sections 6-MS-31 continuations to drawing LR-39233 and drawing LR-39219, location D-7, pipe sections 6-2MS-31 continuation to drawing LR-39234.

NSPM Response: The continuation of drawings LR-39218 and LR-39219, location D-7, Drain to Trap, is shown on LR-39233, location C-2, at valve TD-11-1, and LR-39234, location C-2, at valve 2TD-11-1, respectively.

3/4 Issue: continuations were found, but the scoping criteria of piping section (out of system dashed lines) before valves TD-11-1 and 2TD-11-1 differ between drawings.

RAI: Drawing LR-39218, locations E-6 and E-7, pipe sections 3-MS-30, and upstream pipe sections after the valves TD-6-11, TD-6-12 1 Drains to Trap continuations to drawing LR-39233 and drawing LR-39219, locations E-6 and E-7, pipe sections 3-2MS-

30, and upstream pipe sections after the valves 2TD-6-11, 2TD-6-12 continuations to drawing LR-39234.

NSPM Response: The continuation of drawings LR-39218 and LR-39219, locations E-6 and E-7, Drains to Trap, is shown on LR-39233, location C-3, at valves TD-11-16, TD 11 and TD-6-12 and LR-39234, location C-3, at valves 2TD-11-16, 2TD-6-11 and 2TD-6-12.

3/4 Issue: The continuations were located; however the scoping criteria of piping section (out of system dashed lines) before the valves TD-11-16 and 2TD-11-16 should be 10 CFR 54.4 (a) (1) instead of 10 CFR 54.4 (a) (2).

RAI: Drawing LR-39218, locations E-8 and H-8, pipe sections 1/2 -MS-59, 12-MS-35 respectively, continuations to LR-39233 and drawing LR-39219, locations E-8 and H-8, pipe sections 1/2 -2MS-32, 12-2MS-35 respectively, continuations to LR-39234.

NSPM Response: The continuation of drawings LR-39218 and LR-39219, location E-8, 1/2-MS-59 and 1/2-2MS-32, Drain to Trap, are shown on LR-39233 and LR-39234, location C-9, at valve TD-16-1 and 2TD-16-1 respectively.

3/4 Issue: The scoping criteria of the dashed line before valve TD-16-1 on the continuation drawing LR-39233 at location C-9 differs from that on LR-39218.

RAI: Drawings LR-39218 and LR-39219, location F-6, show a continuation of) pipe sections 1-1/2-MS-40, 1-1/2-MS-41 and 2-2MS-40, 2-2MS-41 from stop valves of drawings LR-39233 and LR-39234, respectively.

NSPM Response: The continuations of drawing LR-39218, location F-6, Drains From Stop Valves, are shown on LR-39233, location A-4, Turb Stop Valve Drains and on LR-XH-2-15, location A-5, Connection 24. The continuations of LR-39219, location F-6, Drains From Stop Valves, are actually connected on LR-39234, location A-4, similar to the Unit 1 drawing; the connections are not explicitly shown. The continuation is also shown on LR-XH-1002-43, locations B-5 and B-6, Connection 24.

3/4 Issue: The continuations were located; however, the scoping criteria of the continuations (as well as the stop valves) on LR-39233 differ. these lines are in scope for 10 CFR54.4(a)(1). Confirm the scoping classification of these lines on drawing LR-39233.
