1.

The inspector stated that the disposition of the contract vari-ations issued for this vessel appears to be satisfactory; however, the following two areas must have corrective action to prevent recurrence.

('~'N The protective packaging to prevent contamination or damage a.

s_,)

of the vessel during overseas shipment.

(Section II, paragraph 6)

b.

If Ishikawajima - Hirama Heavy Industries Ltd. (IHI) will be fabricating any future nuclear vessels, the Charpy Impact Test Machine must be capable of qualification in accordance with the ASTM requirements, or the material shall be qual-ified by a testing agency whose test equipment meets these requirements.

(Section II, paragraph 7)

2.

Quality of Radiographs N- /

The ASME, Code,Section III, 1965 Edition, states in part: ".

..

The weld ripples or weld surface irregularities on both the inside and outside, shall be removed... to surth a degree that the re-sulting radiographic contrast due to any irregularities cannot mask or be confused with the image of any unacceptable discontinuity."

Contrary to the above, the radiographs for the Mk 8. Nozzle to Mk 57 shell weld had what appeared to be the remainder 4of a temporary attachment weld and a weld valley that possibly could mask unacceptable discontinuities.

5.

Placement of Penetrameters i

The ASME Ccde,Section III, 1965 Edition, states in part: ".

..

The penetrameter shall be placed on the side nearest the radiation source.

Where it is physically impossible to do this, the penetrameter may be placed on r.he film side of the joint...: A test radiograph shall be made under substantially identical conditions as will be present on production radiography."

6.

Protective Packaging to Prevent Contamination or Damage A contract variation was issued against the Browns Ferry 3 Vessel, as a result of contamination and damage to the vessel during the overseas shipment.

The contract variation states in part:

. A visual inspection

"

..

of the Final Vessel Assembly, revealed the variations described below:

a.

Twenty-one (21) nozzles were exposed to salt :,2ter during shipment.

In item "d" all the nozzles are identified with their serial numbers and the discrepancies which pertain to

!

each.

Salt water was able to contact these areas because Tectyl was put on only the remaining area of the nozzles after the cap and tape had been applied.

This enabled the salt water to seep under the tape and down through the I.D. of the nozzle.

b)

(

b.

Three (3) of the above nozzles had damaged weld preps.

c.

All (92) stud holes acquired some rust.

This condition was also caused by the contact with salt water, d.

After complete buffing, all carbon steel surfaces were Magnetic Particle inspected, and all stainless steel safe es.ds were Dye Penetrant inspected.

No rejectable indications were found.

f.

The three (3) nozzles that had damaged weld preps were repaired.

The repaired areas were machined to form the weld prep land.

The weld prep was then Dye Penetrant inspected.

There were no rejectable indications.

g.

Due to the rust in the (92) stud holes, all bushings were re-

~

moved.

The stud holes were then cleaned by wire brushing un-til all rust was removed.

The bushings and taperpins were then placed in the stud holes.

After final cleaning prior to shipment, the effluent rinse water of the vessel and head had a conductivity of 1.65 micromhos."

The inspector stated that in the future protective packaging design must be reviewed and the installation of the packaging inspected to assure the required protection.

Qualification of IHI. Charpv Imoact Test Machine It appears that the Pendulum striking edge is not in conformance with ASTM-E23, therefore, the machine cannot be qualified in ac-cordance with this specification.

This deficiency was identifed by B&W, a Contract Variation was issued.

Comparative tests conducted on the IHI machine and a machine qual-ified to ASTM, E23 indicated the IHI machine was 7% below the nominal value of the standards specimen, instead of 5% as permitted by 223.

Since the test values exceeded the minimum requirement by more than 7%, the qualification test conducted by IHI was accepted by General Electric Company.

SECTION III

-

Prepared By:

B. T. Resnick, RO:RCB:HQ Additional Subiects Inspected, Not Identified in Section I, Where No Deficiencies or Unresolved Items Were Found 1.

General As part of the routine vendor inspection, an inspection was made of selected documents covering material certifications, mater-

,

ial receipt inspections, operation processes, welding qualifica-tions, procedures, and controls for the Midland 1 and 2 pressurizers,

B&W contract numbers 620-0012-59-10 and 620-0013-59-10, respectively.

2.

Status of the Two Pressurizers The inspector was advised that the two pressurizers are partially completed to about the same degree of completion.

The shell cour-ses including the heater belts are welded into a single assembly.

The top heads are partially completed with the manway ring, spray nozzle, pressurizer relief nozzle, vent nozzle and lif ting lugs welded into the head.

i

\\'-

The inspector noted that no manufacturing work was being performed on the. pressarizer and that the shell courses and top heads were in storage. The shell courses are stored outside the manufacturing building.

The inspector was advised that the shells are protected from the elements by a coating of Tectyl on the metallic surfaces and are further shrouded with several layers of protective plastic and the seams taped.

The heads are stored inside the manufacturing building without any protective coatings.

-

B&W inspections of the stored assemblies are required to be conducted in accordance with procedure 12-2QT-106 Revision 0.

However, in-spection of the records indicated that a deviation notice had been issued specifying inspection every 90 days. The inspector was advised that the assemblies are being inspected every 30 days but only the 90-day inspection was documented.

B&W advised the inspector that a letter will be sent to shop inspectors specifically requireing docu-mentation of the 30-day inspection findings.

Records Reviewed a.

Material Certifications An examination of the following certified material test reports established that they were in accordance with applicable ASME/ ASTM specifications, code cases, and B&W Specification for Pressurizer, Contract No. 620-0012,13.for Consumers Power Company, approved by B. B. Cardwell, Jr., dated January 21, 1971:

(1) Upper Heater Belt Forging, Specification ASTM A-508 Class 1, modified by code case 1332-4, and ASME Code Section III, Article 3 modified.* Bethlehem Steel Report No. 438, dated March 24, 1970.

(2) Lower Heater Belt Forging, Specification ASTM A-508 Class 1, modified by code case 1332-4, and ASME Code Section III, Article 3 modified.* bathlehem Steel Report No. 473, dated April 2, 1970.

)

(3) Manway Forging. ASTM A-508 Class 1, as modified by code ('~'/

case 1332-4, as modified by customers purchase order.*

x Bonney Forge and Foundry SO No. 0592-0 dated December 30,

The material certifications were signed and dated by responsible personnel of the supplier and B&W.

The transition temperature curves, attached to Bethlehem Steel Report No. 438 were identified as Lower Heater Belt Forging, although the material markings for the material furnished under report No. 438 identified the mater-ial as Upper Heater Belt Forging.

B&W contacted the supplier and

-

determined that this was a typographical error, B&W will obtain a revised report with proper identification.

b.

Cladding Thickness A review of the following records pertaining to cladding thick-ness of the upper head indicated that the upper head thickness was in conformance with B&W Standard Equipment Sepcification for Pressurizer Vessel, Specification No. CS-3-32/0570, dated May 15, 1970:

welding procedures, WP-33 Alt 1 Revision 2, dated February 25, 1970, the Record of Procedure and Qualification Test - QC 2E4-122 dated February 5, 1970, and Weld Control Record - S/N A 019141.

From this examination it was established that the upper head forging, originally purchased for use in B&W contract 620-009, and carrying that identification number, is being used in the contract number 620-012 pressurizer.

d.

Transfer of Identification Marks gs An inspection of shop process sheets and sketches indicated (

that identification marks were satisfactorily places on each

\\-

' segment of the upper and lower forgings were welded and seg-mented.

e.

Deviation Notices Deviation notices, signed and dated by responsible personnel, indicated acceptance of (1) a reduced welding gap between the manway and head; and (2) a reduced welding gap between the lifting lug and head.

_

The records examined also indicated that the weld preheat temperature was maintained in the range of 1500 - 2000F.

The specified weld pre-heat temperature range was 150 F.

A maximum interpass temperature of 5000F was specified while the &ctual (documented) interpass temperature

'

during manufacture was maintained between 150 - 250 F.

These tem-peratures are in accordance with the welding procedure qualification range and in conformance with ASME Section IX, paragraph Q-11, V-5.
