1.0 INTRODUCTION

The purpose of this Inspection Plan is to set forth the criteria used to perform an indirect inspection on piping and piping supports for gross deficiencies of a variety of systems. This Inspection Plan will be implemented by Quality Control at the request of the Nuclear Facility Engineering Department.

A walkdown indirect inspection will be perforrced on the system to docu:nent any gross conditions. The results of the inspection is to be documented on an Attachment I and information provided to Nuclear Facility Engineering Supervisor for evaluation.

• - Additional information in remarks section 5.1.1 Inspect anchor bolts for looseness or pulled out. Where possible, identify any signs that the base plate to anchor interface has shifted, such as chipped or cracked paint around nut, bolt, or washer.

5.1.2 Inspect base plate for signs of movement such as cracked painting, chipped or broken concretc/ grout, etc.

5.1.3 Inspect the thermal insulation in the vicinity of the hanger for any indication of excessive pipe movement. Note any conditions such as crumbling, or displaced insulation blocks, deformed and loose jacketing, etc.

5.1.4 Inspect hanger or support structure for any degrading condition such as bent or deformed members, pipe clamp shif ted or mis-orientated.

3 5.1.5 Inspect hydraulic / mechanical snubber and spring hangers for:

5.1.5.1 Cross failures such as members, piston rod and weld s.

5.1.5.2 Verify pivot pins and retainers / load studs are installed.

5.1.5.3 For hydraulic snubbers verify fluid level is correct and no evidence of leakage. (Should be approx. k full with piston rod fully extended, and 7/8 full with piston rod fully retracted.

Fluid level should be at an intermidiate level with. piston rod at an intermediate position).

5.1.6 Enter initials and date on Attachment I.
