Dear Mr. Grier:

This letter serves to provide the Commission with an interim report of a deficiency regarding the use of pipe shims around anchors between concrete floors and equipment base plates.

The deficiency was originally reported by telephone to NRC Region I Inspector Mr. L. Narrow by Mr. R. A. Schwan of PPGL on November 7, 1980. During that conversation, Mr. Narrow was advised that the condition was under evaluation for reportability under the provisions of 10CFR50.55(e).

The deficiency has been documented by Bechtel under MCAR 1-64 issued on November 4, 1980; and PPaL has subsequently concluded that the condition is reportable under 10CFR50.55(e). The attachment to this letter contains the description of the problems, the approach to resolution along with the basi.s.for reportability.

Since the details of this report- provide information relevant to the reporting requirements of 10CFR21, this correspondence is considered to also discharge any formal responsibili.ty PPGL may have for reporting in compliance thereto.

We expect to provide a fi.nal report on the deficiency in February, 1981.

Very truly yours, tLC (V 5

'O PLA-586 0'TTACHMENT DESCRIPTION OF THE POTENTIAL PROBLEMS Bechtel Engineering became aware that pipe.shims have been used around anchors between concrete floors-and, base. plates. These were used fear setting and leveling of the base plates of various types of supports. The majority of.

the existing. base plates, have been already grouted, however, the annular space between. pipe shim and the anchor is not filled'S'ee Figure 'l.'). The grout, thickne'ss (and. also. the height of the pipe shim) generally r'anges between one and two inches. As. the anchors are unsupported'ithin the height of pipe.shims,, their, shear capacities may b'e significantly. reduced.

I Further communication by Bechtel. Engineering with Bechtel Field. Engineering indicated that this aondition ~ists-..typically on the following types of floor mounted supports:

a. Large and small pipe supports.
b. Instrument. supports
c. Electrical supports Zn addition. to the above condition, on a few floor mounted pipe supports, was observed'hat a nut was placed'within the pipe shim and tack welded.

it (See Figure '2') This'condition may -have an adverse impact in developing and verifying required installation torque/prestress in the anchors.

'PPROACH"TO RESOLUTION OF THE. PROBLEMS

(

On discovery of. the problenrs, Bechtel Field Engineering was instructed by Bechtel Engineering to discontinue use of pipe shims around anchors.

An inspection program is planned to identify and determine the scope of this problem;, Based upon the information obtained, adequacy of anchors will be accordingly evaluated.

For the resolution of the problem> the following options are being considered.

a. Developing an arialytical method for engineering evaluation.

, b. Removing pipe shims, where base plates are not grouted.

c. Filling the annular space with an approved material.

taking the inspection program necessary to resolve the use of pipe shims around anchors. The inspection is scheduled to commence in December 1980. Additionally, the field has established the feasibility of filling the void shown in Figure 1 with grouting material.

Bechtel Engineering is in the process of evaluating this condition by analytical method.

r An inspection and remedial program is presently being planned which will deal with the tack welding of leveling nuts inside pipe shims (Figure 2).

REPORTABZ LXTY PPsL Engineering has determined these- problems to be reportable to NRC under lOCPR50.55(e) for the following reasons.

a. The conditions, had they gone unnoticed, might have adverse impact on the safe operation/shutdown of the plant as these anchors support safety related systems and/or piping.
b. Based upon the-available information, these conditions may require extensive evaluation. and/or repair to meet structural requirements.
