IE INFORMATION NOTICE NO. 85-15:

NONCONFORMING STRUCTURAL STEEL FOR

SAFETY-RELATED USE

Addressees

All nuclear power reactor facilities holding an operating license (OL) or

construction permit (CP).

Purpose

This information notice is provided to alert recipients of a potentially

significant problem pertaining to the structural material provided by steel

suppliers for safety-related use, especially plate that the steel suppliers cut

into small pieces. It is expected that recipients will review the information

for applicability to their facilities and consider actions, if appropriate, to

preclude a similar problem occurring at their facilities. However, suggestions

contained in this information notice do not constitute NRC requirements;

therefore, no specific action or written response is required.

Description of Circumstances

On August 3, 1984, Illinois Power Company made notification of a potentially

reportable deficiency concerning ASTM A-36 plate material. A 1/2 x 15 x 15 in.

plate of steel did not behave as expected in a mechanical cutting operation.

Subsequent testing of this plate showed that the physical properties (yield and

tensile strength) were less than that required by the A-36 material specifica- tion.

Confirmatory testing of samples from other plates having the same

identification number (the material manufacturer's heat number) by a different

laboratory also showed that the yield and tensile strengths were lower than

required.

For all the samples tested with this identification number, the

lowest yield strength was 14% below the ASTM minimum and 23% below the certi- fied material test report (CMTR). The lowest tensile strength was 24% below

the ASTM minimum and 34% below the CMTR.

The certified material test report, which accompanied this material, came from Phoenix Steel Corporation.

The

report showed that the material met the requirements of ASTM A-36 and was

manufactured in 1980.

Subsequently, Phoenix Steel performed a chemical analysis of two other samples

with the same identification number and concluded that this material was not

made by them.

Phoenix Steel makes steel from scrap and the analysis of trace

chemical elements showed a purity not possible from the remelting of scrap

material.

Testing of an additional sample with the same identification by an

independent laboratory confirmed this analysis.

8502200273

IN 85-15 February 22, 1985 The Illinois Power Company began a thorough examination program and discovered

a 1/2 x 10 x 10 in. steel plate with a different identification number that

also had yield and tensile strengths lower than required by the A-36 material

specification.

The certified material test report, which accompanied this

material, came from Bethlehem Steel Corporation. The report showed that the

material met the requirements of ASTM A-36 and was manufactured in the last

half of 1980.

Testing of an additional sample with the same identification by

an independent laboratory also showed yield and tensile strengths lower than

required.

For all the samples tested with this identification number, the

lowest yield strength was 16% below the ASTM minimum and 36% below the CMTR.

The lowest tensile strength was 25% below the ASTM minimum and 45% below the

CMTR.

Neither Bethlehem Steel nor Phoenix Steel sell steel cut into small pieces. In

both cases, an independent supplier, Interstate Steel Supply Company of Phila- delphia, Pennsylvania, provided the material to Illinois Power Company.

Interstate Steel purchases plates, shapes and rectangular tubing in large

quantities from steel mills and other suppliers.

The material is usually

resold, as is, to small users, but occasionally the material is cut into

smaller sizes.

Interstate Steel does not have an ASME Quality System Certifi- cate, but does supply structural steel for safety-related use.

The Clinton

Power Station purchased material from Interstate Steel for safety-related pipe

supports, conduit supports, beam stiffeners, and cable pan hangers.

Tr'EbiTityM

o'6fCut'M'aftera'l

'

Until recently, Interstate Steel had a subcontractor perform all cutting of

plate. A review of certified material test reports, shipping invoices and

purchase orders, as well as discussions with subcontractors, indicated that

traceability was not maintained when material was sent out for cutting.

Interstate Steel was unable to show that the material' that their vendor cut to

size and shipped to Clinton was the material shown on the certified material

test report.

A comparison was made between the quantities of steel listed on the certified

material test report, identified by heat number, and the quantities of steel

received by Illinois Power Company with the same heat number. There were

several instances where the quantities of cut plate shipped by Interstate Steel

exceeded the dimensional limitations of the material supplied under the same

heat number by Bethlehem Steel to Interstate Steel.

The disparities have not

been resolved.

Safety-Related ASME Code Material

A review of certified material test reports, which were supplied by Interstate

Steel for material delivered after April 1982 to Clinton, revealed that Inter- state Steel purchased material from sources that were not approved to supply

ASME material, in accordance with the requirements of Subarticle NA-3700 of

Section III of the ASME Code.

The testing necessary to upgrade the material, as required by Subarticle NA-3700, was not performed.

IN 85-15 February 22, 1985 Interstate Steel maintains inventory records by size, not by heat number, and

it does not retain inventory records beyond 4 years.

The records do not

provide positive identification of the customers for a specific manufacturer's

heat number.

The Illinois Power Company is locating the material that is suspected of having

lower-than-specified yield and tensile strengths and is evaluating the effect

of reduced strength on safety.

Further testing of material is being performed.

Interstate Steel has provided a list (Attachment 1) of the nuclear power

reactor facilities to which they have supplied material.

In two instances, only the name of the utility was furnished.

The list does not contain

information about the safety significance of the material.

No specific action or written response is required by this information notice.

If you have any questions about this matter, please contact the Regional

Administrator of the appropriate NRC regional office or this office.
