Commission

Attn: Document Control Desk Washington, D.C.20555 Gentlemen:

Re: Turkey Point Units 3 and 4 Docket No.50-250 and 50-251 Response to NRC Inspection

Report Number 50-250/251-90-13

Regarding Licensees Commitment

For Hydrogen Recombiners

On May 18, 1990, Florida;*Power

and Light, during a meeting with the NRC concerning

NRC Inspection

50-250/251-90-13, agreed to provide the NRC with information

concerning

Turkey Point,'s implementation

of 10 CFR 50.44"Standards

For Combustible

Gas Control System in Light-Water-cooled

power reactors," and NUREG 0737r item II.E.4.1,"Dedicated

Hydrogen Penetrations".

This commitment

was included as unresolved

item 250, 251/90-13-01

of NRC Inspection

Report 50-250/251-90-

13 dated June 15, 1990.NUREG 0737, Item II.E.4.1, requires licensees to provide containment

penetration

systems for external recombiner

or purge systems that are dedicated to that service only and that meet the redundancy,,and

single failure requirements

of General.Design Criteria 54 and 56 of Appendix A to 10 CFR 50.The penetrations

must be sized to satisfy the flow requirements

of the recombiner

or purge system.Turkey Point Units 3 and 4 have redundant purge connections

which are independent

of the large containment

penetrations.

By letter L-80-16, dated January 11, 1980, FPL compared this design.to the design criteria specified in NUREG 0578, item 215.a (TMI Item II.E.4.1).

At that time, Turkey Point did not employ hydrogen recombiners.

+<el//o On April 17, 1980, Schweaner (NRC)to Uhrig (FPL), the NRC provided its safety evaluation (SE)accepting Turkey Point~~~~plant's actions taken to satisfy the TMI lessons learned category"A" items.As stated in the NRC SE, FPL agreed to 90072400.900716 F'DR ADOCK 05000250 tJ PDC an FPL Group company

re-evaluate

the flow requirements

of the hydrogen purge system for a, post-accident

situation.

Per Inspection

reports 50-250/251-81-10, dated June 18, 1981, the NRC closed TMI item II.E.4.1 (NUREG 0578, item 2.1.5.a)for Turkey Point Units 3 and 4, as well as the open item from the NRC's April 7, 1980 SE, based on the design of the Turkey Point Post-Accident

Containment

Vent System.On December 2, 1981, 10 CFR 50.44 was amended to require plants that do not have recombiners

to have the capability

to install external recombiners.'ollowing

review of the amended rule, Turkey Point elected to install piping and electrical

service for the installation

of an external hydrogen recombiner

in accordance

with 10 CFR 50.44.As stated in the NRC Inspection

Report 50-250/251-90-13, Turkey Point developed an off-normal

procedure providing instructions

on how to obtain a hydrogen recombiner

if the need arises.Previously, Turkey Point had obtained an agreement with other utilities for the use of an external recombiner.

Turkey Point is now actively evaluating

a reactivation

of this agreement and a possible similar agreement with a different utility group.When this agreement is completed, the hydrogen recombiner

will be brought on site to verify system operability.

Should you have any questions on this information, please contact us.Very truly yours, arz'is Vic President Tur y Point Plant Nuclear KNH/DPS/ds
