II. Summary and Conclusions of Overall Effectiveness Since the start of construction. Hidland has experienced some signifi-cant problems resulting in enforcement action (enforcement statistics are shamarised in Table 1). Following the identification of each of these problems, the licensee has taken action to correct the problems and to upgrade the QA program and QA/QC staff. The most prominent action has been an over few program which has been steadily expanded to cover safety related activities. In spite of the sorrective actions taken, the licensee continues to experience problems in the implementation of quality in construction.

Significant construction problems identified to date include:

(1) 1973 - cadweld splicing deficiencies (Paragraph C.2); (2) 1976 - robar omissions (Paragraph 7.5); (3) 1977 - bulge in the Unit 2 Containment Liner Plate (Paragraph G.3); (4) 1977 - tendon sheath location errors (Paragraph G.4); (5) 1978 - Diesel Generator Building settlement (Para-graph N.10); 6-) 1980 - allegations pertaining to Esck Company beating, ventilating, and air conditioning (NVAC) deficiencies (Paragraph J.7);

(7) 1980 - reactor pressure vessel anchor stud failures (Paragraph J.3);

(8) 1981 - piping suspension system installation deficiencias (Paragraph K.4); and (9) 1982 - electrical cable sisinstallations (Paragraph L.2).

Consumers Power has on repeated occasions not reviewed probl'ess to the depth required for full and timely resolution. Esamples are:

(1) rebar omissions (1976); (2) tendon sheath location errors (1977);

(3) Diesel Generator Building settlement (1978); and (4) Eack Company l

NVAC deficiencies (1980). In each of these cases the NRC, in its investigation, has determined that the probles was of greater l

significance than first reported or that the problem was more generic than identified by Consumers power Company.

l The Region !!! inspection staff believes problems have kept recurring at (1) Overreliance on the architect-Midland.for the following reasons:

engineer, (2) failure to recognize and correct root causes (3) failure to recognize the significance of isolated events (4) failure to review isolated events for their generic application, and (5) lack of an aggressive quality assurance attitude.

A history of the Midland design and construction problems and their disposition, as identified and described in NRC inspection reports, is contained in the following section (!!!). This history is for 30, 1982.

the period from the beginning of construction through Jtne L--.
