Reactor Vessel Installation - Work Observation - Unit 2 The licensee's provisions for protection of the installed vessel was inspected. The upper flanged opening into the vessel was observed to be covered and protected with a metal covered platform suspended and sealed in the opening. Fitting of the refueling canal floor plates around the access openings to the vessel nozzle support structures was underway. The interior of the vessel was not accessible at this time.
No items of noncompliance were identified.

Safety Related Pipe Support and Restraint Systems - Units 1 and 2 The following procedures with their recent revisions were reviewed for approvals and scope:
SNP Inspection Instruction (II) No. 66 Revision 7, dated a.
December 11, 1978 titled, " Inspection of Supports."
b.
SNP II No. A-3 Revision 2, dated November 16, 1978 titled,
" Inspection and Cycling of Shock Suppressors."
- c.
SNP Construction Procedure No. P-30 Revision 2, dated December 11, 1978 titled, " Fabrication and Installation of Seismic Supports."
The hydraulic snubbers for Unit 1 are continuing to be rebuilt, recali-brated and reinstalled. The licensee's representative stated that about 40 more units were left to complete the Unit 1 installation; the Unit 2 snubbers would start to be processed after that. The licensee's representatives were encouraged by this inspector to pass along their experiences related to snubber installation to their counterparts at the Watts Bar, Bellefonte and Hartsville sites.
No items of noncompliance were identified.
