GE Follow-up Action to 2/11/93 Phone Call with NRC Staff re: SSAR Chapter 14 - Initial Test Program Item 1 - Applicability of Reg Guide 1.140 Staff Comment - The staff noted that in Section 14.2.7, "Conformance of Test Program with Regulatory Guides, Reg Guide 1.140, " Design, Testing and Maintenance Criteria for Normal Ventilation Exhaust System Air Filtration and Adsorbtion Units of Light Water Cooled Nuclear Power Plants", was included as being applicable while in Table 1.8-20, "RGs Applicable to ABWR", it was listed as being not applicable.

GE Responce_ - Table 1.8-20 is correct.

The ABWR does not include any

" normal" atmosphere cleanup systems.

The only atmosphere cleanup systems that exist System and a dedicated portion of thein the ABWR design are the Sta system.

Main Control Room ventilation

" Design, Testing and Maintenance Criteria for Post Accid Safety-Feature Atmosphere Engineered-Cleanup System Units of Light-Water-Cooled Nuclear Power Plants" Air Filtration and Adsorbtion No other ABWR ventilation systems perform an atmosphere cleanup function, and thus they have no equipment requirements of Reg Guide 1.140.(HEPA filters, charcoal beds, etc.) subject to the Therefore, the reference to RG 1.140 in Section 14.2.7 of the SS AR will be deleted in a future Amendment attached markup).

(see Item 2 - Radioactive Waste Systems NRC Comment - Section 14.2.12.2.38, "Radioactis e Waste Systems Performance" describes the power ascension testing for both gaseous and liquid radwaste systems while Table 14.2-1, " Power Ascension Test Ma trix",

includes only an entry entitled " Liquid RadWaste Systems Performance" GE Response - The entry in Table 14.2-1 was intended to include testing o both gaseous and liquid radwaste systems.

This intent will be clarified in a future SSAR amendment (see attached m ark up).

Item 3 - COL ltems NRC Comment - In Section 14.2.13. " COL License Information - Initial Test Program", it is stated that the COL applicant is to provide the final list of tests proposed to be exempt from license conditions requiring NRC preapproval of changes to the testing specified.

Justification for each item on this list should also be provided.

GE Response - GE agrees.

This is what was intended, although not explicitly stated.

This will be clarified, via addition of an explicit requirement, in a future SSAR amendment (see attached markup).

Item 4 - Cross-Reference to Utility Organization NRC Comment - In Section 14.2.2.1, " Normal Plant Staff", a reference is made back to Chapter 13 for information regarding the plant owner / operator's organization.

However, in the ABWR SSAR, that particular information is listed as being out of scope.

GE Response - GE will revise the wording of 14.2.2.1 to clarify that such information is the responsibility of the COL applicant, and thus will be supplied at a later date (see attached markup).
