O UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION BEFORE THE ATOMIC SAFETY AND LICENSING BOARD In the Matter of HOUSTON LIGHTING & POWER COMPANY

)

Docket No. 50-466 1

(Allens Creek Nuclear Generating

[)

Station, Unit 1) t AFFIDAVIT OF RALPH 0. MEYER CONCERNING DOHERTY CONTENTION 45 My name is Ralph 0. Meyer.. I am employed in the Nuclear Regulatory Commis-s sion as Section Leader of the Reactor Fuels Section in the Core Perfomance Branch. My professional qualifications are attached as Enclosure 1 to this affidavit. This affidavit was prepared under my control and supervision.

The purpose of this affidavit is to address Doherty Contention 45 which reads as follows:

4 Intervenor contends that lateral support of the ACNGS reactor core is not sufficient to withstand the lateral force applied to the 1

core due to flashing which occurs near the end of the subcooled blowdown portion of the LOCA transient. Further, that such a 4

lateral force has not been considered in Applicant's NSSS vendor's analysis and may result in a 10 - 15% change in maximum calculated impact load for a given 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 NUREG/CR-1018 " Review of LWR Fuel System Mechanical Response with Recomendations for Component Acceptance Criteria". Applicant's fuel assembly support l

against lateral LOCA forces should be increased by:

i 4

,80 0 s i s o 'iS7

L..

..... -........ -.. 1.

additional lateral support equal to 30% of the support against the Safe Shutdown Earthquake, or 2.

a factor for a LOCA or Safe Shutdown Earthquake - LOCA analysis of 1.3.

This contention evidences a concern that the lateral support of the ACNGS reactor core is not sufficient to withstand lateral blowdown forces because it has not considered flashing loads which occur during a loss-of-coolant accident (LOCA). Particularly, the Intervenor alleges that an additional load from steam flashing in the core might increase the fuel loads by 30%

under some circumstances.

It is clear from the contention that the concern is based on a proposed revision to the Standard Review Plan / and is described in " Review of LWR Fuel System Mechanical Response with Recommendations for Acceptance Criteria,"

P NUREG/CR-1018, published in September 1979.

I However, the 30% increase in LOCA fuel loads only affects PWR fuel assembly analyses and, therefore, is not applicable to ACNGS which is a' BWR.

There are two reasons why this load applies only to PWRs.

First, a PWR operates below the boiling point (subcooled) whereas a BWR operates at the boiling point of the water coolant. As stated in Conten-tion 45, the lateral (fuel) force is due to " flashing which occurs near the I 1/

Proposed Revision to the Standard Review Plan, Notice of Availability, 45 Fed. RS.19939 (February 27, 1980).

l l

]

O end of the subcooled blowdown portion of the LOCA transient." Since the BWR

~

does not operate in the subcooled regime like the PWR analy7ed, it is not

[

possible to have these flashing loads in a BWR.

Second, the lateral flashing loads in a PWR result from cross core flows.

The PWR fuel bundles in the core are open to allow a mixing of flows between bundles. The BWR fuel bundles are encased in channel boxes to prevent cross flow. Since the cross core flow is limited in the BWR, the flashing loads (if they could occur) would be lower than in a PWR, For these reasons, flashing loads do not apply to a BWR LOCA. Thus, the contention shculd be dismissed on the basis that the loads in question are not present at ACNGS. ACNGS has complied with all requirements related to the ability of the core to withstand lateral seismic forces combined with lateral blowdown forces.

Frrf e r ri ena! Due!' firet f en?

Ig In 1960 I received a 2.5. in physics from the University of Kentucky and was made a mesber.or Phi Beta Kappa.

In 1966 I re-ceived a Ph.D. from the University of North Carolina (Chapel Hill) with a thesis subject in the fle3d of solid state physics.

~

Follo ing graduation, diffusion studies related to the thesis topic were continued while I was a Research Associate in physics at the University of Ari:ena. In 1968 I was employed as n'n Assistant Metallurgist in the reactor development program of the Materials

, Science Division at Argonne National Laboratory, Illinois. At Argonne diffusion techniques were applied to study the properties

~

of nuclear reactor fuels. Tnis research included studies of gaseous fission product migration, segregation of fissile fuel material, and restructuring of oxide fuel elecents.

More than 20 technical journal

)

papers and topical reports were published on this fundar. ental and applied research.

In 1973, I joined USNRC as a Reactor Engineer in the Reactor Fuels Section of the Core Performance Branch. In addition to other duties related to the performance of nuclear fuel I was the principal

~

reviewer of fuel densificatic, analyses. Since 1976, I have been the Section leader of the Reactor Fuels Section and have a continuing responsibility for the review of fuel densification, fission gas release and overall fuel performance.
