Scope of' Inspection i
The scope of the inspection was limited to the review and
{-
examination of the quality assurance program procedures and instructions established by Texas Utilities Services, Inc.
]
(TUSI) for that phase of the Limited Work Authorization (LWA) request involving the safe shutdown impour iment dam (SSI).
2.
Schedule The TUSI' representative provided the RO_ inspectors with the tentativa SSI dam design completion schedule.
The schedule reflects design input document development complete by July 16, 1974, with the final design submitted to TUSI for final review by September 2, 1974.

'3, Safe-Shutdown Impoundment Dam (SSI) Design
. Freese,and Nichols.(F6N) through the TUSI Project Manager is responsible for.the SSI design..His organization takes the soils design
' information provided -by Mason-Johnson Associates (MJA) and develops the design.
-l The QA Manager of F6N is responsible for the QA activities as they
. pertain to; design and field QA/QC direction.
'The F6N QA Engineer is responsible for directing all field QA/QC activities which includes directing the MJA Field Testing Engineer in~all QC activities.
.a.
QA Program The initial draft (March 20,1974) of F6N's QA Program was observed to have been developed by Nuclear Services Corporation.
The final-draft of the program was evolved July 12, 1974, after.
'approximately three interactions; however, the inspector was
-advised that F&N is still reviewing comments by TUSI on the QC procedures.
A draft policy statement indicated that the complete document will be endorsed by a corporate official.
Review of Section 6.0., " Construction Control" revealed several incensistencies in light of more specific delineation of
_ responsibilities and interfacing activities of F6N, MJA and B&R.
Specifically, Section 6.0 cust be revised to correct organizational-responsibilities in regard to Item 4.5.4. of paragraph L
. " Preparation of Project Specifications',
Procedures ~omd Instructions", and as delineated.n a letter, R. W. Caudie to L. A. Ashley,'7/15/74,'"Organi 'tional Relationships".
Also QC Procedure, Appendix B, "SSI Dam Project External Interface Control" must be revised to reflect the above letter.
Additional QC procedures must be developed by F6N for implemen-tation of additional activities included.
b.
Program Commitment F&N is committed to Appendix B, 10 CFR 50 for design and I
construction'of-the dam.
The program also declares implemen-tation in accordance with guidance presented in N45.2 and
'N45.2.11 (Draft No.-3, Rev. 1).

c.
. Organization
,The QA program describes organizational functions in the areas of administration, projects and QA.
The QA Manager is a member of the management council and is responsible b'
for formulating and administering the QA program as it relates to the SSI dam.
The QA coordinator is responsible for verification of implementation of the SSI dam QA program.
The QA Manager appears to have the necessary authority for implementation of the QA program uith a direct line of comnunication to a proper level of management.
d.
Review of Program by Management F&N will perform QC of the2.r cwn activitics and a second level surveillance function of inspection and testing.
Th>I will audit F&N design activities in accordance with Section 3.0 of the
{
CPSES QA Plan, "Proje :t Construction Surveillance".
TUSI is presently expanding on Section 3.0 to include specific surveillance activities for construction of the SSI dam.
1 These will be reviewed and verified for implementation during dam construction.
U e
~
Design Control c.
A design input document which identifies codes and standards; Regulatory requirements; design criteria and properties of the foundation, abuteents, and borrow material; has been developed.
Once the excavation has been completed to unweathered rock, design of the dam can be completed.
The design control portion of the program provides for and establishes responsibility for development of design bases; preparation and issuance of drawings and other design documents; and for correction of deficiencies.
No deficiencies were identified by the RO inspector during review of design control procedures.
f.
Audits Review of audit procedure, Appendix I, " Conduct of Audits",
revealed that it generally addresses disposition of deficiencies noted during auditing but it does not reference Appendix G,
" Corrective Action" as the mechanism for control of deficiency resolution.
Also, paragraph 6.19 which addresses review, approval and distributica of the final audit report is not definitive enough from the point of view it does not designate action required for designated responsible personnel.
The procedure does not specify an audit schedule.

a.-
The_MJA Chief Engineer is responsible for the soils design of the SSI dam. His organization establishes the soils design parameters required for F&N to complete the design.
b.
The.MJA Manual:(Draft dated 7/8/74)-has not been finalized
'and the~ letter'of promulgatien contained therein had not
-been signed in the space provided for the MJA President, Mr. Raymond C.' Mason; however, the MJA program appeared
.to be adequate for the scope of work to be performed by BOA.
- c. ~ By separate document, FDA has provided TUSI with the soils design parameters and the qualitative acceptance criteria to be. maintained during the SSI dam construction.
d.
During the review of the above documents, the inspector
-observed.that, although the above docu=ents were Loth thorough and comprehensive, the QC procedures for the on-site quantitative testing requirements have not been provided.
In discussing this matter with the TUSI
==
representatives,.the-inspectors were informed that F6N will initiate the development of the applicable outstanding procedures in a timely manner commensurate with the site progress (see Management Interview).
This matter will be reviewed dur'ing a subsequent RO inspection.

b.
The B&R Project-QA Manager is responsible for collecting all QA documentation required-for the dam.
In addition, the.B&R QA/QC' organization is monitoring all-B&R construction activities.
c.
The inspector reviewed the applicable B&R QC procedure, CP-QCP-12, " Excavation, Soils Backfill, and Embankments",
-dated July 1, 1974.
It was observed by the inspector that although the document does allude to dam construction, specific referenceor requirements relating to the established MJA construction' criteria was not apparent.
In discussing
~
this matter with the TUSI representatives, the R0 inspector, was-informed,that F&N will initiate the development of
~
arn'icable QC and work procedures for the B&R scope of work.
