Eisenhut Director, Division of Licensing Office of Nuclear Reactor Regulation U.S. Nuclear Regulatory Commission Washington, D.C. 20555 Re: Docket Nos. 50-329 OM, OL and 50-330 OM, OL Midland Nuclear Plant - Units I and 2 Independent Design and Construction Verification Program (IDCVP)
Draft Report on the Control Room HVAC System Performance Requirements Gentlemen:
Attached is our recently completed draft report on the Control Room Heating, Ventilating, and Air Conditioning (CR-HVAC) System Performance Require-ments. This report is the second in a series of design verification topical reports that will collectively document the review process and conclusions. As such, design verification octivities are ongoing, and this report represents partial fulfillment of the objectives of the IDCVP.
A final report will include on integrated assessment which assimilates the specific topical reports into general conclusions.
The scope addressed in this topical report includes elements of the CR-HVAC system design specifically related to how the primary functional requirements are met (e.g., system operating limits, pneumatic design, pressurization require-ments, instrumentation and control, etc.), corresponding to topics listed under section i of the CR-HVAC sample review matrix defined in the IDCVP Engineering Program Plan. A similar topical report will follow, oddressing the system performance scope for the standby electric power system.
System Protection Features and Structures that House the System (sections 11 and 111 of the sample review matrices, respectively) will be addressed in two additional topical reports which will cover these aspects for all three systems.

Based upon our review arid ind w !+t egrGnatory evaluations, we have concluded that for topical v w wMNn the sccpe of this report, odequate confidence exists that the CR4NAC v3 tem will perform its intended safety functions.
As discussed in Section 5.2 of the report, items noted during the course of this review have raised issues which are currently subject to cdditional verification.
While the safety significance of the noted issues has been assessed relative to topics within the scope of this report, the intent of the ongoing verification activities is to determine whether or not these L, sues have potential broader implications that may affect other design features of the Midland plant. We will report on the results of these investigations in our final report.
The draft report will be finalized upon receipt of Midland project comments.
These comments will be appended in unedited form, and all changes to the body of the report will be appropriately identified.
The above planned activities are, of course, dependent upon Consumers Power Company's actions regarding the future of the Midland project.
Should you desire further clarification of the bases for our conclusions, we would welcome the opportunity for discussion.
Sincerely, f
