NUCLEAR REGULATORY COMMISSION

[Docket No. 50-483]


Union Electric Company; Notice of Partial Withdrawal of 
Application for Amendment to Facility Operating License

    The U.S. Nuclear Regulatory Commission (the Commission) has granted 
the request of Union Electric Company (the licensee) to partially 
withdraw its June 27, 2003, application for proposed amendment to 
Facility Operating License No. NPF-30 for the Callaway Plant, Unit 1, 
located in Callaway County, Missouri.
    The request for amendment to the operating license in the 
application dated June 27, 2003, would allow plant modifications in 
order to facilitate maintenance on the replacement steam generators 
(SGs) to be installed in Refueling Outage (RO) 14 (Fall 2005). The 
proposed modifications (1) replace the existing sludge lance platforms 
with new platforms to provide a larger platform area around each SG, 
and (2) cut a permanent access opening through the secondary shield 
wall to improve access to the sludge lance platforms, which are to be 
done in RO 13 (Spring 2004). To allow these modifications, the licensee 
requested approval of the use of (1) the ASCE 4-86 ``100-40-40'' method 
of combining components of seismic response loads, and (2) leak-before-
break (LBB) methodology for the accumulator, pressurizer surge, and 
residual heat removal (RHR) lines to exclude the dynamic effects 
associated with large reactor coolant system branch line ruptures. The 
amendment approving the installation of the permanent access opening 
through the secondary shield wall and the use of LBB for the 
accumulator and RHR lines was issued April 12, 2004, and the opening 
was installed by the licensee in RO 13.
    The Commission had previously issued a Notice of Consideration of 
Issuance of Amendment published in the Federal Register on July 22, 
2003 (68 FR 43397) for the application for amendment dated June 27, 
2003. However, by letters dated April 5 and July 2, 2004, the licensee 
withdrew portions of its amendment request. The letter dated April 5, 
2004, revised the original request for application of LBB on the 
pressurizer surge line and the letter dated July 2, 2004, withdrew its 
request to use the ASCE 4-86 methodology. The Commission has previously 
issued a Notice of Partial Withdrawal of Application for Amendment 
published in the Federal Register on April 20, 2004 (69 FR 21166) for 
the letter dated April 5, 2004. This Notice of Partial Withdrawal of 
Application for Amendment is for the letter dated July 2, 2004.
    For further details with respect to this action, see the 
application for amendment dated June 27, 2003, and the licensee's 
letter dated July 2, 2004, which partially withdrew the application for 
license amendment. Documents may be examined, and/or copied for a fee,
