CP-86-36 (INTERIM REPORT)
Dear Mr. Johnson:
On June 9,1986, we verbally notified you of a reportable item involving the scope of plant modifications resulting from the project's pipe support reverification program (see TXX-4844). This is a follow-up interim report on a reportable item under provisions of 10CFR50.55(e). Our latest interim report logged TXX-6117 was submitted on November 25, 1986.
The continuing engineering evaluation has not identified any additional instances which are considered reportable pursuant to 10CFR50.55(e). The attached list shows the support modifications issued to date. The evaluation is continuing and we anticipate submitting our next report by February 20, 1987.
Very truly yours, MklYb

- 1 Prudent 862 Recent Industry Practice 1303 Adjustment 655 Cumulative Effects 853 2
Prudent 1265 Recent Industry Practice 286 Adjustment 184 Cumulative Effects 474 Changes in these figures from the last report represent not only identification of further modificatio:s but a reclassification and/or recategorization of certain supports.
Reductions in these figures from the previous report are due in part to the removal of some small bore pipe support modifications which were inadvertantly included in_ the previous report.
