All The procedure provides a method for the performance and documentation of EQ walkdowns.
Revision 0 applies only to those EQ walkdowns performed as part of the Environmental Qualification Enhancement Progrcm.
The applicability of the procedure will be expanded upon completion of Environmental Qualification Ennance'sent Program or at an earlier date if so directed by EQ Project Managet'. The orogram is designed to provide corrective I
action iglementation as part cf an NRC commitment.

CONFIGURATION FOR 10CFR50.49 EQUIPMENT CHECKL!$T i
This form is a means to verify the plant as built configuration meets the EQ j
requirements specified in EQ test reports, instruction manuals, regulatory notices, and FPC analyses.
Exhibit 1 is designed to allow the addition of i
necessary sheets.
For instance, if one page for Section 2.0 does not provide sufficient space to record the instruction manual information, additiorial Sectf on i
2.0 sheets may b3 added to the velkdown package.
Exhibit sections applicable l
to a tpocific walkdown must be identified in the appropriate section on papa one of Exhibit 1.
Ncn applicable sections should be discerded or NCd.
f 1.0 IDENTIFICATION OF E3UIPMENT TO BLH[Q,y.ERlrtED_(.[tMbitJ.ALA).
The assigned Design Engineer must cor.plete Exhibit 1,. Part A, ar.d the assigned Verification E:igineer must verify the accuracy of the informatien L
recorded per the refnrences utilized. The assigr.ed Design Engineer scall l
obtain a W,11kdown Package Nuniber from the log maintained by the EQ l
Supervisor.
1.1 Block A.1 and A.2.
The assigned Design Engineer shall review the electrical circuit of the 'end device' in the 10CFR50.49 program. A loop diagram must be developed from the applicable electrical drawings, raceway i
schedules, termination sheets, and block diagrams. Each discrete component l
in the block diagram must be identified (such as junction boxes, terminations, pull boxes, splices, penetrations, cables, end devices, etc.)
l back to the entrance to the control complex. Block A.2 shall be utilized to document each discrete component identified, the manufacturer /model number of the discrete component and the applicable sections of Exhibit i
l 1 to be utilized.
Pull boxes (no terminations) and condulets are to be verified not to contain splices, using Exhibit 2.
NOTE: The purpose of the loop diagram is to identify any ancillary components and/or electrical splices.
Partial loop walkdowns may be performed to address specific concerns related to individual end devices or loop components.
In this case, the full loop diagram must indicate which portions of the loop shall be verified by walkdown.
This is accomplished by indicating the boundaries of the walkdown with dashed lines and icoicating the walkdown is a partial walkdown in Block A.2.
Only the discrete components to be walked down are recorded in Block A.2.
