2.

Site Tour

The NRC inspector toured the reactor building, control room and auxiliary

building for Units 1 and 2 to observe construction in progress and to

inspect housekeeping.

No violations or deviations were identified.

3.

Observation of Safety-Related Electrical Equipment

The NRC inspector selected several examples of electrical equipment and

components for examination.

The examination consisted of verifying that

the field installation agreed with applicable design drawings and that

separation and protection requirements were being met.

The following

equipment and components were inspected:

o

125 VDC Battery Charger (CIDJBC047G)

o

125 VDC Battery Charger (BIDJBCD47E)

o

125 VDC Battery Charger (DIDJBC047D)

The NRC inspector visually inspected the electrical equipment and

components listed above. During this visual inspection, the NRC inspector

found one deficiency. The 120 VAC Distribution Panel identified as

3E241EDP001 had been signed off as completed according to installation

records. All required documentation indicated that this panel was

completely installed. However, a review of "as built" drawing

14926-4363-00001, Revision 5 (S.0.5647-C1) indicated that the referenced

panel had not been properly inspected to verify that field welds were

installed in accordance with instructions.

This is an apparent violation of Criterion X of 10 CFR Part 50, Appendix B

(498/8604-01).

4.

Review of Safety-Related Electrical Equipment Records

The NRC inspector reviewed Bechtel and EBASCO quality assurance (QA)

inspection reports to determine whether adequate documentation existed to

control electrical equipment activities in the following areas:

(a) receipt inspection and storage, (b) handling and in-process

installation, and (c) qualification and training of craft personnel,

a.

Receipt Inspection and Storage

The NRC inspector examined Bechtel QA documentation pertaining to the

receipt inspection and storage of electrical equipment. The records

examined appeared adequate to ensure that incoming electrical

equipment conforms to purchase specifications, and is properly stored

to protect against construction damage and adverse environmental

conditions. The documents and records examined are listed below:

documentation.

(2) Physical conditions (such as damage, deterioration, etc.) were

identified and documented.

(3) Nonconforming component items placed in storage were identified

as required.

Failure to Properly Inspect

Criterion X of Appendix B to 10 CFR Part 50 requires that activities

,

affecting quality be subjected to an inspection program to verify

conformance with the documented instructions, procedures and drawings for

accomplishing the activity.

This requirement is amplified by the approved

,

Quality Assurance Plan Description (QAPD) for the South Texas Project.

-

i0.

QCP 10.15, Revision 3, paragraph 5.2.3.B states that the Quality Control

, , .

Inspector (QCI) shall verify all field welds required have been inspected

and accepted by recording the completed acceptable welding inspection

report number on the installation inspection package.

is

Contrary to the above, the weld configuration on Panel 3E241EDP001

differed from the weld configuration shown on "as built" drawing

is-

14926-4362, indicating that the panel installation had not been properly

inspected to verify that the field welds were in accordance with

n

instructions.

This is a Severity Level IV violation (Supplement IE) (498/8604-01).
