Meeting Details A meeting was held in the NRC Region III office in Glen Ellyn, Illinois to discuss the Midland Unit I reactor vessel holddown anchor bolt pro-blem and our investigation of allegations relating to the heating and ventilation installation work performed by Zack Company for the Midland proj ect.

Consumers Power Company also described what organization

-

changes have been made and/or are contemplated to centralize control of activities associated with the Midland project.

a.

Reactor Vessel Holddown Anchor Bolt Failures RIII personnel described their findings of investigation conducted

at the Midland Site, Consumers Power Company Corporate Offices,

.

Bechtel Corporate Offices, Southern Bolt and Fast ener Corporation, Mississippi Valley Structural Steel Company and.. W. Rex Company.

These investigations concluded that the reactor vessel holddown anchor bolts were rejectable for their intended purpose due to poor bolt material selection and heat treating processes. These problems resulted in bolts that have high notch sensitivity due to extreme high surface hardness.

The licensee presented findings which include,d'past history of the bolts, engineering findings of laboratory testing of the failed bolts and. engineering plans for possible design modi-fications that would reduce the stress on the bolts.

The NRC stated that any modifications where the bolts were not used in their original intended design would have to be re-viewed by NRR. Consumers Power Co. acknowledged this and requested that a meeting be set up in the near future to dis-cuss technical details associated with proposed alternatives.

The NRC stated that RIII findings would be presented in a separate inspection report in the near future.

b.

Investigation of Heating and Ventilating Contrator RIII personnel A scussed their findings resulting from allega-tions received that heating and ventilation work was not being done in accordance with regulatory requirements at the Midland

site. Numerous examples of failure to maintain material control

,

and traceability were found. A number of procedural violations of the Consumers Power Company and Zack QA programs were also

,

noted.

l The NRC noted that, while Consumers Power Company and Bechtel

,

~

'

had already identified a number of these problems with Zack Co. and had instituted a number of programs for corrective actions, these actions were insufficient to. preclude recurring j

failures to meet regulatory requirements. Consumers Power Company discussed a program for correcting problems identified by themselves and the NRC. After some discussion, the NRC requested that Consumers Power Company provide a written pro-

,

gram that would address the corrective actions that would be

'

taken to remedy and preclude repetition of the problems.

The NRC rtated that the findings of the investigation of the

~

Zack Co. would be the subect of a separate report and the enforcement action to be taken 5y the NRC was being reviewed.

c.

General The NRC also requested that the licensee review and revise as necessary their QA program for determining severity of adverse-3-

trends, for providing management assecsment of those trends, for providing qualitative defined thresholds for required cor-rective actions including work stoppage, for determining root causes and for providing effective actions to correct past problems and to preclude future problems.

Further,-the NRC requested that the licensee review their files to determine if other items were purchased in which there was no inprocess source inspection and the files indicate that the manufacturer had difficulty in meeting the purchase specifica-tions, such as had occurred during manufacture of the reactor vessel holddown anchor bolts. The results of thir review is to be made available to our inspectors.

d.

Consumers Power Company - Midland Reorganization Consumers Power Company discussed their revised organization to centralize control of the Midland project.

Mr. J. W. Cook was introduced as the Vice President for the Midland project. A discussion was held of a proposed reorganization of the QA

,

organization.
