1.

Storage of NSSS Equipment (R0 Inspection Reports No.

050-329/74-11 and No. 050-330/74-11)

-

The licensee has not yet inspected and documented NSSS equipment internals "as received" conditions.

This item was considered unresolved.

2.

Water in Unit No. 1 Containment (RO Inspection Reports No.

050-329/74-11 and No. 050-330/74-11)

Unit No. I containment steel liner plate floor section welding had been completed. Nitrogen purge has been applied on all leak chase internals. The inspector reviewed CP Project QA Service Daily Log Sheet indicating:

(1) observation on welding, (2) removal of water prior to welding, (3) welders's qualification check, and (4) proper procedures used. The matter was considered resolved.

Management Interview A.

The following persons attended the management interview at the conclusion of the inspection:

G. L. Richardson, Lead Quality Assurance Engineer J. P. Connolly, Project Field Quality Control Engineer J. F. Newgen, Field Supervisor-B.

Matters discussed and comments, on the part of management personnel, were as follows:

1.

The inspector stated that the corrections and resolution of the rebar spacing nonconformance appear to be adequate, with the exceptions of some questions raised relative to the design parameters used in the calculation of the structual integrity of the containment wall.

The licensee indicated that additional information would be developed and that this would be expected to be completed by early March 1975.

, A, j 2.~

Th'e inspector. stated that he had no further questions relative to the fire' damage of Unit 2 containment.

However, he. urged

"

' that the engineering disposition of NCR No. 239 (for.the liner

,

l coating 1 repairs) show some considera-lons of possible adverse

_

,

impact for an 18-month delay in completion of repair.

The licensee' indicated that it would be taken into consideration.

-3.

.The inspector indicated his understanding that the licensee is planning to inform Region III by letter of the personnel changes affected by.the curtailment of construction activities.

The licensee indicated that a letter is presently being prepared and that, in addition, the Licensing Board will be informed, also by letter, in the near future.

'4.

~The inspector indicated that present long-term NSSS equipment-storage procedures and surveillance program appear to be in effect and adequate.

(Report Details,Section I, Paragraph 3)

,

5.

The inspector questioned the meaning of extended long-term storage of NSSS equipment onsite.

The-licensee responded that

" extended long term" means more than a one-year period.

The licensee has committed April 1, 1975, as a target date to complete their studies and furnish a workable procedure ~for the task.

f'~'N)

6.

The inspector stated that Unit No. I containment water problem

during base plate welding has been resolved and that he had no further questions.

7.

The-inspector acknowledged the licensee's comments on the last

inspection report ~ (No. 050-329/74-11 and No. 050-330/74-11) and will' record these comments in the next inspection report (Attachment A, this report).

8.

The. inspector stated that, during the review of concrete placement records for ~ pours No. CC(622. 25)a' and ik). A(589.75)a', he established that there appears to be no systematic method of

. obtaining samples for slump, air, and strength tests relative

~

.to complying to the sampling frequency as stated in the PSAR and the specification.

The licensee agreed to investigate and, if possible,. establish a' systematic method of obtaining samples.

9. -

The inspector stated, during the review of NCR's submitted by the licensee, the following areas appear to be possible generic problems:

a..

A number of NCR's were initiated because of equipment and/or

materials arriving at the job site without proper documentation.

Results of Inspection

'

1.

Unit 2 Containment Liner Rebar Spacing Nonconformance

'The inspector reviewed the rebar spacing calculations and indicated that there was insufficient information on documentation and justification of formulas chosen, design and analysis conditions assummed, and the allowables used.

Verification checklists should also be a part of the report. presentation. The licensee has committed March 15, 1975, as a target date to resubmit calculations for'IE:III inspection review.

The inspector reviewed:

(1) Bechtel QA to CP letter, dated January 24, 1975, transmitting Field Instruction Civil (FIC) No. 7, approved on January-23,L1975, to-be used on rebar spacing inspections.

This instruction detailed the reasonable, usual occurring deviations from

. spacing of rebars which ;can to allowed, and the others that must be documented and approved,'and (2) Bechtel QC to CP letter, dated-January 24, 1975, stating'that a review indicated that proper rebar spacing had been maintained in accordance with FIC No. 7.

The

~

inspector was informed 1by the licensee that a training session had-been _hvid on January 27, 1975, : regarding this method.

The rebar

. spacing-check-procedures appeared to be satisfactory.

Fire in Unit 2 Containment Documentation was reviewed by the inspector that established the acceptability of the containment liner and concrete of Unit 2 containment that was-subjected to a fire on November 21, 1974.

The

'results of testing and the engineering cvaluation appeared adequate and acceptable. Documentation reviewed included:

a.

Bechtel NCR's No. 266 and No. 238.

b.

An engineering evaluation and disposition prepared by Bechtel design engineers dated January 9, 1975.

'3.

Outside Storage of NSSS Equipment

,

The inspector-reviewed Bechtel's Unit 2 NSSS equipment long-term storage requirements and considered that adequate, protective measurements had been taken.

These procedures had been approved

^

by B&W, the NSSS supplier.

.The. inspector' inspected the Bechtel storage and maintenance and/or inspection records and considered that a proper surveillance program on Unit.2 NSSS equipment had been in effect.

The settlement

' readings on the Unit 2 reactor, steam generators, and pressurizer

"

were required'by B&W and recorded by.Bechtel Engineering Department.

The inspector also reviewed handling procedures on NSSS equipment, qualifications and testings of the lif ting.nachine and haroware,-and also the personnel training and checklists for handling the NSSS equipment. Documentation appeared to be adequate.

Review of Bechtel Specification No. 7220-C-230, Revision 5 Dated November 22, 1974, Entitled " Technical Specification for Subcontract for-Operating Onsite Batch Plant and Furnishing Concrete for the Consamers Power Company Midland Plant" The inspector reviewed.the referenced specification, and the following was established:

PSAR, page 5-6, paragraph 5.1.1.3.1, states, in part, that:

",.

.. a low slump of two or three inches are used.

.".

.

..

Tabic 9.1, of the above specification, has a slump rejection limit of 4 1/2" to 5" pending on the classification of concrete.

CP stated that this-discrepancy is due to the fact that the specification has an inadvertency margin, and the PSAR will be revised accordingly.

.

This matter will be reviewed during the subsequent inspection.
