Subject:

Submittal Supporting Accelerated ABWR Schedule - Generic Fuel Licensing (Item #17)

Dear Chet:

Enclosed is the SSAR markup addressing Generic Fuel Licensing item #17. We plan to include this in Amendment 32 which is scheduled to be transmitted to the NRC on August 31,19993.

Please note that Appendix 4D is proprietary in that it demonstrates that Chapters 4 and 15 meet the proprietary acceptance criteria of Appendix 4B. Please handle Appendix 4D accordingly.

Please provide a copy of this transmittal to George Thomas.

Sincerely, h Ay Jack Fox Advanced Reactor Programs cc: Alan Beard (GE)

4.2 Fuel System Design The fuel system is defined as consisting of the fuel assembly and the reactivity control assembly. The fuel assembly is comprised of the fuel bundle, channel and channel fastener. The fuel bundle is comprised of fuel rods, water rods, fuel rods containing burnable neutron absorber, spacers, springs and assembly and fittings.

The fuel to be loaded in an ABWR is any fuel design that is approved by the USNRC or that meets the criteria documented in Appendix 4B. Using these designs will assure that all fuel system design requirements are met. GE g -

uder TA Y d y To demonstrate ABWR system response in this SSAR, a reference core o BP8x8R fuel is used. This core is shown in Section 4.3; information for this fuel design is provided in A Reference 4.2-1 Each COL applicant referencing the ABWR design may have different fuel and core de igns which will be provided by the COL a plicant to the USNRC for NO information. k e n w'* Pbrs"a"aev 0

Regarding the reactivity control system, this Section 4.2 addresses only the reactivity control elements that extend from the cou li ' interface of the control rod drive mechanism (per Regulatory Guide 1.70 Revision : . The functional design of the reactivity control system is detailed in Section 4.6.

4.2.1 Design Bases 4.2.1.1 Fuel Assembly The fuel assembly (comprised of the fuel bundle, channel and channel fastener) is j designed to ensure that possible fuel damage would not result in the release of j radioactive materials in excess oflimits prescribed by 10CFR20,50 and 100. Evaluations are made in conjunction with the core nuclear characteristics, the core hydraulic I characteristics, the plant equipment characteristics, and the instrumentation and i i

protection systems to assure that this regt irement is met.

The thermal-mechanical design process emphasizes that:

(1) The fuel assembly provides substantial fission retention capability during all potential operational modes.

(2) The fuel assembly provides sufficient structuralintegrity to prevent operational impairment of any reactor safety equipment.

The fuel assembly and its components are designed to withstand: ,
