))HOUSTON LIGHTING & PONER COMPANY

)Docket No. 50-466

)(Allens Creek Nuclear Generating

)Station, Unit 1)

).)JOIEi F. DcRERTY'S CCUTIITIOU #45, NEED FOR ADDITIONAL LATERAL SUPPORT IN THE REACTOR CORE.

John F. Doherty, Intarvenor in the above Construction License proceeding files this Contention J45, and supporting statement to justify lateness in filing.

________CONTENTION #45 Intervenor contends that lateral support of the ACUGS reactor core is not sufficient to withstand the lateral force applied to the core due to flashing which occurs near the end of the subcooled blowdown portion of the LOCA transient.

Further, that such a lateral force has not been considered in Apolicant's USSS vendor's analysis and may result in a 10 - 15;s change in maximum calculated impact load for a civen spacer grid, and a 30% increase in impact load is likely if two fuel assemblies interact at the periphery of the core.

Following the recommendation of liUREG/CR-1018, " Review of Li/R Fuel System Mechanical Response with Recommentations for Com-ponent Acceptance Criteria", Applicant's fuel assembly support acainstlateral LOCA forces should be increased by:

1) additional lateral supp~ ort equal to'305 of the support against the Safe Shutdown Earthquake, or

2) a factor for the LOCA or Safe Shutdown Earthquake - LOCA analysis of 1.3

_________SUPPORTIUG STAT.31EUT This Interve mr's sole source of information on lateral loads of this severity being introduced in the event of LOCA is HUREG/CR-1018, which was first available to him on October 24, 1979 Although the publication date is September, 1979.
