Subject:
Combustion Engineer:ng Standard Safety Analysis Report -
Design Certification, Submittal Group D: Amendments to Chapters 2, 3, 4, 5, 6, 7, and 18 l
f I
Dear Mr. Miraglia:
This letter transmits the next in Combustion Engineering's series of l
modifications to the Combustion Engineering Standard Safety Analysis Report - FSAR (CESSAR-F).
Since the purpose of our modifications is to l
upgrade our current Final Design Approval (FDA-2) to a Design Certification, we refer to the reviced CESSAR-F as CESSAR-DC.
As you l
are aware, the enhanced and expanded design described in CESSAR-DC l
will be called the System 80+ W Standard Design.
The enclosure to this letter provides you with our draft revisions to sections of Chapters 2, 3, 4, 5, G, 7 and 18.
The attachment to this letter provides a brief summary of the enclosed revisionn.
l Revisions relative to CESSAR-F are identified by a bar in the right-hand margin.
To distinguish the amendmenta to CESSAR-F which are intended to lead to Design certification from the amendments made in the course of updating CESSAR-F, we are using a lettered amendment system for CESSAR-DC. This lettered amendment system was introduced in the submittal of Reference ( A).
The enclosed revisions to Chapters 2, 3, 4, 5, 6, 7, and 18 are identified as Amendment D.
We hope to formally submit a set of printed CESSAR-DC volumes to you in the near future. With that submittal, we intend to formally request opening of a separate docket for CESSAR-DC, as described in References 8810110320 ssono PR ADOCK 05000470 PDC Power Systems 1000 Prospect Hal Road (203) 688 1911

(B) and (C).
The issue of the category and limit of the fees to which we will be liable [ Reference (D)], however, continues to remain an impediment to our submittal. We are appreciative that this matter has been taken under advisement and is being given serious consideration [ Reference (E)). We are hopeful that, when this matter is resolved by the Commission, the result will be a satisfactory resolution of our concerns, removing this impediment to our submittal.
In the meantime, however, we request that a means be found which will protect our rights and thus allow the technical review to proceed unencumbered.
If we can be of any additional assistance in this matter, please feel free to call me or Mr. E. H. Kennedy of my staff at (203) 285-4520.
Very truly yours, COMBUSTION ENGINEERING, INC.
