Inspection of Reactor Vessels (RPV) Components
, , An' examination of the RPV components for Units 1 and 2 established that the RPV for Unit 1 was in four major assemblies, and the RPV ' for Unit 2 was complete and being cleaned in preparation for hydrostatic testing. No workmanship deficiencice were identified.
The B&W representative said-the hydrostatic test of the Unit 2 RPV was estimated to be-performed subsequent to September 2, 1974.
L - 3.
Base Material Test Reports (MTR's) A review of base material test report packages for seven components ~ for the Unit 2 RPV established that the information and test data was in accordance with the requirements of the applicable ASME/ ASTM specifications and the special General Electric Company (GE) require- ' ments. The subject components and the respective specification are , as follows: , ' - a.
Vessel flange, A-508-64, Class 2.
, b.
Closure head flange, A-508-64, Class 2.
c.
Four recirculation nozzles, A-508-64, Class 2.
, d.
Closure head dome plate, SA-333-67, Grade B, Class 1.

Weld Metal Analysis Report
A review was made of the B&W weld metal test specimen report, common to the closure head girth veld for Unit No. 2.
The weld , wire and flux were fully identified. The weld metal physical and , chemical test data and Charpy-V impact. test values at + 10*F were
' determined to be acceptable by B&W.
' 5.
Deviations Only three finalized contract variations (CV's) were generated since November 1973 for the work on Unit 1.
The B&W representative stated no finalized CV's for Unit 2 were available.
Review of Unit 1 CV's ' , i established they were complete and fully implemented and approved in ' accordance with the B&W system.
In all three cases, the disposition of the'CV's'was to use "as is".

Welding Equipment Calibration a.
Procedures ~A review of B&W Technical Procedure No. 12-2-GEM-5, Revision L 0, " Maintenance of Welding Equipment", established that it . governed the preventive maintenance (PM) programs for welding equipment. The equipment was defined as power sources, , manipulators, positioners, drum turners, and turning' rolls.
~ The procedure noted that it did not apply to out-of-service ' equipment.
. The responsibility of the maintenance and construction (M&C) , group included checking th'e accurancy of portable ampere and j voltage meters on a monthly basis, attaching a calibration ' - [ sticker, and sending the meters to the QC gage room for semi-l' annual recalibration against master meters traceable to the National Bureau of Standards.
Calibration of new equipment,
prior to its use, was also an M&C responsibility.
- ,
One section 'of the procedure appeared inconsistent in that it
stated that ampere and voltage meters for manual metal arc ! (MMA). welding machines were.not to be calibrated to the- { subject procedure.
Instead, they were to be checked in
accordance~with Technical' Procedure No. 12-2-GEM-4, Revision 5,.." Gage Control Program". Review of this procedure by the inspector established that it did not appear applicable to, calibration of meters for MMA machines but, instead, applied 'to pressure gages and other mechanical measuring devices, i .) - Further review established that provisions for checking' welding . parameters, as voltage, during use of MMA welding machines, i.
. .were provided for in Quality Program Procedure No. 12-2-QP-113, .
Revision 0, and QC Technical Instruction No. 7604-511-08.

Matters discussed and comments, on the part of management personnel, were as follows: ~ \\ . - 1.
The inspector commented that review of B&W Technical Procedure j No. 12-2-GEM-5, Revision 0, " Maintenance of Welding Equipment", contained a paragraph which stated, in essence, that ampere and voltage meters for manual arc weld machines would be calibrated in accordance with B&W Procedure No. 12-2-GEM-4.
However, the inspector's review of Procedure No. 12-2-GEM-4 failed to identify calibration provisions for subject equipment.
The reference appeared to be in error.
/N l (,).. The B&W representative acknowledged this matter appeared to be in error and said that it would be corrected.
The licensec representative said he will transmit this matter to his manage-ment and, at a later date, he will verify that the procedure - - , ' is corrected.
(Report Details, Paragraph 1.a) ' 2.
The inspector said that, with regard to the balance of procedures and records reviewed, and discussions and observations common to Midland Units No. 1 and No. 2 work, he had no questions at ' i this time.
