Dear Ms. Histt:
This is in response to your Petition of July 22(Director) questing that the 1988, re Director Office of Nuclear Reactor Regulation
, take issnediate 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.
The specific relief requested is to order all BWR licensees to (1) place their reactors in cold shutdown (2) develop and implement s ecified procedures relating to the themal-h,draulfc instability issues, p(3) demonstrate that certain specified traint has been provided relating to these procedures (4) demonstrate the capab 11ty of instrumentation related to power oscil,
lations, (5) develop strulators 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 pumps havs tripped off.
BWRs, and (8)(submit a report to the NRC within one year demon coepliance with GDC 12.
You also request that tne Comission reopen Generic Issues B-19, B-59, the ATWS rulemaking and reconsider the use of End-of-Cycle l
Recirculation Pump Trip on BWRs.
i 1
Your request for iszediate relief is denied because the allegations which form the basis for your Petition do not reveal any new operational safet which pose an irriediate safety concern for continued BWR operation.y issues The staff has determined that continued operation of BWRs is justified for the following reasons:
(1) Current BWR Technical Specifications place restrictions on power operation of the reactor under conditions of natural circulation or single recirculation loop cooling such that operation in regions of low thermal hydraulic stability is limited to % frequent short-term transient conditions following anticipated operational oc,currences.
(2) Neutron flux esc 111ations are detectable with proper monitoring and can be easily suppressed b eset11ations should occur,y inserting control rods. If large and a manual scram is not initiated it i
is expected that the high mer level, Average power Range Monitor (APRM) scram protection, witch terminated the LaSalle event, would provide backup protection as was the case during the LaSalle event.

(3) The magnitude of neutron flux escillations 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 Ins section Team (AIT) for the March 9,1988 LaSalle event reported that tie
{
amplitude of the heat flux oscillations during the event were estimated to be less than 105 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 with guidance on the proper methods to monitor for thermal-hydraulic instabilities and on the actions that should be taken to suppress such oscillations if they should occur. Most BWRs aave implemented such methods in response to NRC Generic Letter 86-02 which provided for s
the technical resolution of Generic Issue B-29. The operating limits-tions which ensure compliance with GDC 12 are enforced by plant technical specifications.
i (5) Compliance with the reconnendations in NRC Bulletin No. 88-07 will ensure that any Itcensed reactor operator or shift technical adviser perfonning shif t duties at a BWR will have been thoroughly briefed regarding the LaSalle events and that all BWR licensees will have adequate procedures and operator training prograns in place to address power oscillations, regardless of the results of any 1
previous thermal-hydraulic stability analysis. The NRC will perform inspections and take any necessary follow-up action to ensure that
- rocedures and training i
aave been put in place. (trograms 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 S
i Federal Register is enclosed for your infonnation.
Copies of this letter are being sent to those named on the service lists for facilities listed in.

RECE1PT OF PETITION FOR DIRECTOR'S DECTSION 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 ternediate action with respect to Boiling Water Reactors to relieve 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 1esnediate relief was denied because the allegations which form the basis of the Petition did not reveal any new operational safety issues which pose an 1evrediate 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.
