ARIZONA PUBLIC SERVICE COMPANY (APS) PVNGS UNIT 1-I. Description of Deficiency Inspection af ter hot functional testing revealed that various loose parts (i.e., washers and a 3 inch type plug) were found in Unit 1 Steam Generators No. I and No. 2. It has been determined that the loose parts came from Combustion Engineering (C-E) temporary instrumentation hardware installed inside the Reactor Pressure Vessel (RPV) on the Core areas. This instrumentation was used to provide baseline data during the ' Pre-Critical Vibration Monitoring Program (PVNP). The 4 instrumentation was removed from the RPV af ter completion of the test. II. Analysis of Safety Implications Bechtel requested assistance from C-E in evaluating and dispositioning this condition and concurs with the attached CE disposition that the condition is not safety significant. The temporary instrumentation hardware size and material selection was

           ~

based on worst case hardware breakaway, so. that vital areas of the Steam Generators would not be harmed by this condition. Also, the testing flow parameters indicated that any loose parts would be

                          ' trapped and easily removed upon completion of the PVMP. Therefore, this condition is evaluated as not reportable under the requirements of 10CFR50.55(e).

III. Corrective Action

                    -               A. Loose parts will be removea from Unit 1 Steam Generators No. 1 & 2. NCR SM-2435 will refer to DER 83-54 and be dispositioned based on this corrective action.

B. The RPV and remainder of the PCS system will be inspected for loose parts after RPV head rencval. C. Action to preclude recurrence is not applicable since the PVMP will only he performed in Unit 1 (Reference V-CE-15987, dated 2/26/82). C

Dear Mr. Bin 6 ham:

9'<' 7 Z The cerditiens listed in the subject DER, received by Reference (A) .have r er_. T review 2d and the fellewing is eur evaluatien as to the reportability in acccrdance with 10CFR 50.55(e). It has been deter ~:ined that the leese parts care frem temperary instru .er.tatien irstalled fer data acquisitien during pre-service testing. B e calfuretien cf si .a will ret jeepardize eperatien er the Steam Generaters. We Icese parts will impact the primary head and tubesheet in a ccepletely rardem manner therefere, repeatedly striking the same peint is extremely unlikely and there will be no expesure of base tetal. h e tubes are recessed (,, in the tubesheet therefere the size of the leese parts preclude them damaging any of t.he heat transfer surface. The material of the leese parts is cer.patible with the clad en the primary head so that there will be no cerresive effects. . In CE's epinien, the deficiency is cet repertable under 10CFR 50.55(e). CE's evaluaticn was perfermed in acccrdance with eur Quality Assurance er Cesign Mar.ual as indicated by FAR No. 14273 -958 (Unit 1). These decuments are available fer review at the CE Windsor effice. Very truly yeurs, C. Fergusen Project Manager CF/JJS/mr cc: Messrs: E. E. Van Brurt, Jr. G. C. Andegnini J. Verees
