1. Page 3.3-1.

Definitions are added for Trip Setpoint and Allowable Value.

2. Pages 3.3-2a, 26, 2c, 3a and 3b replace old pages 3.3-2 and 3.3-3.

A Trip Setpoint and Allowable Value are now specified for each parameter and two curves are used with Table 3.3-1.

Basis for LSSS 3.3

1. Pages 3.3-4 through 3.3-9 replace old pages 3.3-4 through 3.3-8.

The new basis discusses the methodology for determining Trip Setpoint and Allowable Value and then describes the basis for each limiting safety system parameter.

Definitions added for Trip Setpoint and Allowable Value.

Two para-graphs of old page moved to next page.

2. Page 4.4-2.

The paragraph on Table 4.4-3 expanded and page reformatted.

3. Tables 4.4-1 through 4.4-4.

The tables were reformatted to provide for a Trip Setpoint and Allowable Value to replace the Trip Setting.

Each table was split into Part I containing Trip Setpoint and Allowable Values for each parameter and a Part 2 containing Minimum Operable Channels, Minimum Degree of Redundancy and Permissible Bypass Conditions. Part 2 follows Part 1 for each table.

Notes for Tables 4.4-1 through 4.4-4.

Note (a) deleted as Table 4.4-1 line items 3a. and 3b. refer operator to Table 3.3-1.

Note (d) deleted as the Trip Setpoint and Allowable Value in new tables provide specific criteria for the Plant Electrical System - Loss parameter. Note (h) in existing license split into two separate notes (hl) and (h2) to more correctly reflect applicable permissible bypass conditions for the different types of moisture monitors.

Basis for LCO 4.4-1

1. Pages 4.4-10 through 4.4-13 of existing license replaced by new pages 4.4-10, 10a, 10b, 10c, 11, lla, lib, 12, 12a, 12b and 4.4-13.
