NUCLEAR REGULATORY COMMISSION s

WASHueo TON, D. C. 30846 August 26, 1988 Ms. Susan L. Hiatt Representative of Ohio Citizens for Responsible Energy, Inc.

8275 Murson Road Mentor, OH 44060

Dear Ms. Hiatt:

This is in response to your Petition of July 22, 1988, requesting that the Director, Office of Nuclear Reactor Regulation (Director), take ispediate I

action with respect to Boiling Water Reactors (BWRs) to relieve what you allege to be undue risks to the public health and safety posed by the thermal hydraulic instability of boiling water reactors, as revealed by an event at LaSalle County Station Unit 2 on March 9, 1988 i

The specific relief requested is to order all BWR licensees to (1) place their reactors in cold shutdown, (2) develop and implement specified procedures relating to the thereal hydraulic :nstability issues, (3) demonstrate that i

certain specified training has been provided relating to these procedures, (4) demonstrate the capability of instrumentation related to power oscil-lations, (5) develop simulators capable of modeling power oscillations similar to those occurring at LaSalle and out-of-phase power oscillations, (6) report to the NRC regarding all past incidents in which recirculation purps have tripped off,)(7) submit to the hRC justification for continued operation of BWRs and(8 submit a report to the NRC within one year demonstrating compItancewithGOC12.

You also request that the Coenission reopen Generic I

Issues B-19, B 59, the ATW5 ruleraking and reconsider the use of End-of-Cycle Recirculation Fump Trip on BWRs.

Your request for irrediate relief is denied because the allegations which form the basis for your Petition do not reveal any new operational safety issues which pose an irs,ediate safety concern for continued BWR operation. The staff has determined that continued operation of BWRs is justified for the following reasons:

(1) Current SWR Technical Specifications place restrictions on power operation of the reactor under condittens of natural circulation or single recirculation loop cooling such that operation in regions of low thermal hydraulic stability < s limited to infrequent, short-term transient conditions following anticipated operational occurrences, i

(2) Neutron flux oscillations are detectable with proper monitoring and

{

can be easily suppressed b oscillations should occur,y inserting control rods.

If large and a manual scram is not initiated, it is espected that the high power level, Average Power Range Monitor (APRM) scram protection, whten terminated the LaSalle event, would provide backup protection as was the case during the LaSalle event.

I 1

e

^

Susan L. Hiatt (3) The magnitude of neutron flux oscillations induced by thermal-hydraulic instability is considerably higher than the oscillations in the average cladding heat flux because of inherent delay in the transfer of heat through the fuel rods. The NRC Augmented Inspection Team (AIT) for the March 9, 1988 LaSalle event reported that the amplitude of the heat flux oscillations during the event were estimated to be less than 10% of the value for the neutron flux oscillations and that because of the smaller changes in heat flux, thermal limits for the fuel were not exceeded.

(4) General Electric Company has provided BWR licensees w'th guidance on the proper methods to monitor for thermal-hydraulic instabilities and on the actiont that should be tak6n to suppress such oscillations if they should occur. Most BWRs have implemented such methods in response to NRC Generic Letter 86-02 which provided for the technical resolution of Generic Issue B-19.

The operating limita-tions which ensure compliance with GDC 12 are enforced by plant technical specifications.

(5) Compliance with the recorinnendations in NRC Bulletin No. 88-07 will ensure that any licensed reactor operator or shift technical advisor performing shif t duties at a BWR will have been thoroughly briefed i

regarding the LaSalle event; and that all BWR licensees will have adequate procedures and operator training programs in place to address power oscillations, regardless of the results of any previous thermal-hydraulic stability analysis. The NRC will perform 1

inspections and take any necessary follow-up action to ensure that procedures and training have been put in place. programs acceptable to the technical staff Your Petition is being treated under 10 CFR 2.206 of the Comission's regulations. Appropriate action will be taken within a reasonable time. A copy of the notice that is being filed for publication with the Office of the Federal Register is enclosed for your information.

Copies of this letter are being sent to those named on the service lists for facilities listed in.

Sincerely,

,e k

COMMONWEALTH EDISON COMPANY (LaSalle County Station, Unit 2)

RECEIPT OF PETITION FOR DIRECTOR'S DECISION UNDER 10 CFR 2.206 Notice is hereby given that by Petition dated July 22, 1988, Ohio Citizens for Responsible Energy, Inc. requested the Director of Nuclear Reactor Regulation to take imediate action with respect to Boiling Water Reactors to reliave what Petitioner alleged to be undue risks to the public health and safety posed by an event at LaSalle County Station, Unit 2, in Illinois on March 9, 1988.

Petitioner's request for imediate relief was denied because the allegations which form the basis of the Petition did not reveal any new operational safety issues which pose an imediate safety concern for continued BWR operation.

The Petition is being treated pursuant to 10 CFR 2.206 of the Comission's regulations. As provided by i 2.206, appropriate action will be taken on the Petition within a reasonable time.

A copy of the Petition is available for inspection in the Comission's Public Document Room, 1717 H Street, NW., Washington, D.C.

20555 and in the local public document room for LaSalle County Station Unit 2 at Jacobs Memorial Library, Illinois Valley Comunity College, Rural Route One, Oglesby Illinois 61348.
