INTRODUCTION This report describes the inspection program of reactor internals and is submitted in accordance with USNRC RG 1.20, Rev. 2.
The Indian Point No. 2 plant has been established as the prototype for a four-loop plant internals verification program, and was fully I
instrumented and test:sd during Hot Functional Testing.
I Seabrook Station is similar to Indian Point No. 2. The only signifi-
- cant differences are the modifications resulting from the use of I 17 x 17 fuel, replacement of the annular thermal shield with neutron shielding panels, and the change to the UHI-style inverted top hat i support structure configuration. These differences are addressed in detail in FSAR Subsection 3 9(N).2 3 Since the Seabrook reactor internals design configuration is well characterized, the vibration measurement program was omitted and the inspection program was imple-mented, as discussed in USNRC RG 1.20.

SUMMARY
The overall inspections performed on the. reactor internals were governed by Westinghouse Assembly Specification 2463A68. This specifi-cation documents the verification of critical areas on the internals package from initial installation prior to Cold Hydre Testing through Hot Functional Testing up to the final Westinghouse Quality Release prior to core loading.
Incorporated as part of this series of internals inspections is Westinghouse drawing 6125E73, vibrational Check-Out Functional Test Inspection Data, which delineates 28 items which were verified both prior to Cold Hydro Testing and after Hot Functional Testing.,
Documentation of the completion of these inspections and any findings are included as part of prenperational test 1-PT(I)-43, Reactor Post-Hot Functional Inspection.
Examinations included visuni inspection of welds, surface conditions ,
and locking devices and feeler gauge verification of critical contact aaeas. Welds were examined using 5-10x ma.nification. Indications of cracks located on the vessel clevis pins were discovered prior to testing and removed after Hot Eunctional Testing. No other indica-tions vere evident. Interface sur f ac'es were inspected for any evidence of damage. None was found. Bearing surfaces were examined using 5-10x magnificatioa for evidence af (amage. No damage was found. Locking devices were verified to 'oe crimped and undamaged.
Inserts were exanined for the required maximum gap using the
, appropriate feeler gacger. Two upper core plate inserts were found to have excessive gap and t'ere subsequently restored to meet the design gap and contact area. No apparent defects were found at the other insert locations.
During the performance of the vessel and internals inspections, and any work resulting thereof, the refueling cavity access was controlled by appropriate houcekeering requirements. Tool control was maintained to assure that equipment could not be left in the system. The inter-nals were maintained wrapped in plastic and the vessel covered when-ever work on these components was not in progress. After Hot Functional Testing, personnel working on the internals wore clean overalls and protective foot covering.

D. Those other locations on the reactor internal components which are similar to those which were examined on the prototype designs.
- Upper support column nut to extension welds.

- Outlet nozzle interface surface condition.
- Neutron shield panci screw locking devices.
- Interface surfaces at the spacer pads along the top and bottom ends of the neutron panels.
- Baffle assembly screw locking arra~ngements at the twc top and the two bottom former elevations.
- Irradiation specimen guide screw looking devices and dowel pins.
- Vessel nozzle interface surface condition.
- Guide tube screw locking devices.
E. The inside of the vessel will be inspected before and after the Hot Functional Test, with all the internals removed, to verify that no loose parts of foreign material are in evidence.
Prior to Hot Functional Testing, the vessel, closure head, upper internals and lower internals were inspected to a cleanliness level that meets and exceeds Class B requirements as specified 'n .
ANSI N45.2.1-1973 After Hot Functional Testir.g, the vessel, head and internals were inspected for foreign maturial. The full flow filters were removed and inspected for any debris. No loose parts were found. The inspection prior to testing is documented by pro- ,
cedure RC-F-5. Inspections performed after testing are documented by preoperational test 1-PT(I)-43, Section 6 3 4
