J RECORD OF TRAINING 1-Project Identification No.2-ESSE/AS-001 EBASCO SERVICES INCORPORATED ST.LUCZE UNIT 82 PROCEDURE INSPECTION OF CONEGETE MASONRY WALLS 1.0 PURPOSE The purpose of this procedure is to describe the method of field investiga-tion and data compilation for use in the masonry wall design re-evaluation.

2.0 SCOPE

Phase I Inspection

-The buildings on the St.Lucie Unit 82 site that contain concrete masonry walls covered by this procedure-are the Reactor Auxiliary Building, Reactor Containment Building, and the Fuel Handling Building.The RAB has many-concrete masonry walls performing various functions throughout the building.The RCB contains one concrete masonry wall'near the pressurizer at Elevation 73.00'or radiation shielding.

The FHB has two concrete masonry walls at Elevation 19.50'or shielding around the valve chamber for the'uel pool purification filter.Phase I of the inspection will be to identify the number, location and type (i.e., reinforced or non-reinforced) of all concrete masonry walls in the above buildings.

This will be accomplished by using the Ebasco concrete masonry wall drawings along with a confirmatory plant walk through and a spot check on each wall for the verification of the existence of reinforcing (reinforcing bar and/or dur-o-wall)

..2 Phase ZZ Inspection

-This phase will be, to inspect the concrete masonry walls identified in Phase I;to identify and locate safety related items mounted on the walls or in close proximity to the walls and to record the location to verify wall thickness&composition (where possible)and weight of significant safety related and non-safety related items mounted on the walls..3 Phase ZII Verification

-After the inspections are completed the capacity of the concrete masonry walls to withstand design loads will be verified.

However, some systems have been completed and turned over to Florida Power a Light.Care must be exercised to avoid any accidental up-setting of instruments, equipment or systems.Also, many electrical items are energized.

The inspector is warned to avoid any contact with these items.0 PROCEDURE.1 PHASE I a)All concrete masonry wall drawings (Reference 3.4)will b'assembled:and from them a reproducible set of'eference drawings will be made.Each concrete masonry wall will be given a unique number and the type of wall (i.e., reinforced, un-reinforced and cantilevered) will be indicated.

The master reference drawings will be made from sepias of General Arrangement drawings (Reference 3.2)and will be given field sketch G size (FSG)numbers in accordance with Company Procedure E-74.The person completing the FSG drawings will initial them in the"DRAWN BY" section of the title block.b)An inspection data sheet will be produced for each wall shown on the master reference drawings.(See attachment

$1).The person px'oduc-ing the data sheet will fill in the following information:

Wall Number Wall Surface Reference Drawing (FSG)Plant Area (RAB, RCB, or FHB)Floor Elevation'-0.50', 19.50', 43.00', 62.00'Location (HVAC RoomE Locker Room, Drumming Station, etc)Function of Wall (shield wall, pressure retaining wall, etc)Thickness and Composition of wall Type of Reinforcement

-Horizontal Type of Reinforcement

-Vertical The person preparing the inspection data sheet will sign the sheet in the"PREPARED BY" section.

Project Identification No.2-ESSE/AS-001 PROCEDURE FOR INSPECTION OF CONCRETE MASONRY WALLS.0.l PHASE I (continued)

~~c)A detailed walkthrough of the Reactor Auxiliary Building will be performed by Engineering personnel, to identify concrete masonry walls and insure the completeness of the master reference drawings.Care will be taken to insure that all areas of the RAB will be inspected.

The engineers performing the walkthrough will initial the FSG drawings in the"CHECKED BY" section of the title block.d)The master reference drawings will be maintained by the Ebasco Site Support Engineering Group (ESSE).e)During the walkthrough, each concrete masonry wall will be scanned with a metal detector-James Electronics Model C-4952 R-Meter, or equivalent

-to verify the existence of reinforcing (reinforcing bar and or dur-o-wall).

The R-Meter measures the disturbances by external magnetic material of a magnetic field generated by the probe.The R-Meter will be used to detect the existence of reinforcing.

No attempt will'e made to determine reinforcing bar size or depth of embedment, therefore no calibration of the instrument is required.Each inspector will:read'he James R-meter.Operating Manual (Attachment

$6).Each wall will be scanned with the James R-Meter horizontally to verify the existence of at least one reinforced-vertical column as shown on the Reference 3.4 drawings and scanned with the James R-Meter vertically for at least six (6)courses of concrete masonry units to verify the existence of at least two (2)durm-wall reinforced horizontal joints.This information will be entered on the inspection'ata sheet and the person performing the inspection will initial the data sheet in the"PHASE I INSPECTION BY" section.f)All entries made on the inspection data sheets shall be made in black ink.Copies of the data sheets may be made for use as a field work copy.The person doing the inspection must then transfer any markings from the copy to the original..2'HASE II INSPECTION:

All walls identified and verified in the Phase I inspection will be further inspected as follows: 1 a)The wall will be located and a survey made to determine if there is any safety related equipment in the vicinity of the wall or if there is any safety related equipment mounted on the wall.0 b)If there is no safety related equipment identified,"No Safety Related Equipment" will be written on the inspection data sheet and the inspector(s) will go on to the next wall.c)If there is safety related equipment identified, the inspection will proceed as follows:

Project Identification No.2-ESSE/AS-003.

PROCEDURE FOR INSPECTION OF CONCRETE MASONRY WALLS 0.2 d)The thickness a composition of t he wall will be verified if possible.e)A sketch will be made of the wall locating all significant safety related a non-safety related equipment loads on the wall.f)Dimensions on the sketch shall be plus or minus six (6)inches.g)Loads will be distributed to the location of the thru bolts used in mounting the item.Zf the center of gravity of the item is within l'-0 of the face of the wall, this cantilever will be ignored and loads will be directly distribut'ed to the thru-bolts.

h)If available, existing field change requests (FCR's)that detail items mounted on the block wall shall be attached to the data sheet.i)Photographs may be used for reference or backup if the inspection team considers them helpful.All photographs will be identified with the wall number and surface and attached to the data sheet for that w'all~j)The person performing the inspection will initial the'data sheet in the"PHASE ZZ INSPECTION BY" section.k)All entries made on the inspection data sheets shall be made in black ink.Copies of the data sheets may be made for use as a field work copy.The person doing the inspection must then transfer any markup from the copy of the original..3 PHASE IIZ VERIFICATION:

a)Copies of all inspection data sheets will be forwarded to the N.Y.O.lead A-S Engineer for evaluation.

Wall Designs will then be evaluated and verified by the pew.York'f f ice.b)Following~the New York Office review wall acceptance or repair suggestions will be forwarded to the field for evaluation.

c)Following disposition, the ESSE lead A-S Engineer will sign the inspection data sheet in the"VERZFIED BY" section.6.0 SZMiATURE LIST.l All personnel involved in this inspection shall have their full name typed, their handwritten signature and initials recorded on the subject list (Attachment N2).e RESPONSIBILITY This procedure will be maintained by the ESSE office.The signature of the ESSE Project Engineer is required for implementation.
