281-8 The EPRI ALWR Requirements Document, Chapter 3 Paragraph 4.27, 4

requires a plant design which provides system features which t

i facilitate compliance with EPRI NP-5056-SR. PWR Secondary Water i

Chemistry Guidelines. Section 10.3.5 does not reference the EPRI i

Secondary Water Chemistry Guidelines. A generic secondary water chemistry program that conforms with SRP Section 5.4.2.1. Branch Technical Position MTEB 5.3 should be provided.

{'

281-9 '

Section 10.3.5 provides operating chemistry limits for secondary l

steam generator water, feedwater and condensate. Normal and Abrorwal l

limits are provided for secondary water. However, the three action levels and corrective actions to be considered (as recosmended by the EPRI PWR Secondary Water Chemistry Guidelines) are not provided.

281-11 Section 10.3.6.2 does not include materials selection recesmendations in EPRI ALWR Requirements Document (Chapter 1, Section 5.3.5) regarding prohibition of copper alloys and design considerations 4

identified in EPPI NP-2294. "Guide to the Design of Secondary Systems and Their Components to Minimize Oxygen-Induced Corrosion" for the steam and feedwater system.

281-12 Section 10.4.6.2, item 4. the purpose of the resin traps should be included (i.e., to remove resin fines).

Item 5 should include the i

requirement that the minimum flow rate of the condensate polisher should be specified by the manufacturer to prevent channeling.
