4.3.10 Basis (1) Added " subsystems" to list of items required to be protected by snubbers.

(2) Added clarification of permissible reactor operation at power with defective safety related equipment.

Table 4.3.10-1 Reformatted snubber listings. Deleted BFS-824 and added many new hydraulic snubbers per the Seismic Piping System Redocumentation Program.

Table 4.3.10-2 Added new table of mechanical snubbers.

5.3.8.b) Revised section to state acceptance criteria for visual inspections and requirements for functionally testing snubbers which appear inoperable.

5.3.8.c) Revised section to define testing frequency, representative sampling metheds for each type of snubber for functional testing, and addition of Figure 5.3.8-1 for use with sample plan 2. Definition of an engineering evaluation.

5.3.8.d) Revised section to state the acceptance criteria for functional testing of hydraulic snubbers.

5.3.8.e) Added new section to state the acceptance criteria for functional testing of mechanical snubbers.
