Arkansas Power & Light Company P. O. Box 551 Little Rock, Arkansas 72203

Dear Mr. Cavanaugh:

This confirms our telephone and telefaxed authorization given September 19, i

1980 for a change in Technical Specificatione, for Arkansas Nuclear One, Unit 2 as rcquested in your letter of September 16, 1980.

Facility Operating License No. NPF-6 is amended on this date by making the following Technical Specification changes:

Revise Section 3.6.2.3 to read as follows:

3.6.2.3 Two independent containment cooling groups shall be OPERABLE with at least one operational cooling unit in each group.

(d) With any cooling unit of the above required groups inoperable because its associated fan is inoperable, verify that the OPERABLE cooling unit in that group has a service water flow rate >l250 gpm through its cooling coils or restore the inope7able cooling unit to OPERABLE status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTOOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />, i

}

Revise Section 4.6.2.3 in its entirety to read as follows:

4.6.2.3 Each containment cooling group shall be demonstrated OPERABLE:

a.

At least once per 14 days by:

1.

Verifying a service water flow rate of >!250 spm

~

to each group of cooling units.

2.

Chlorinating the s.rvice water during the surveillance in 4.6.2.3.a.1 above, whenever service water temperature is between 600F and 800F.

b.

At least once per 31 days by:

1.

Starting (unless already operating) each operational cooling unit from the control room.

801007,o M f

c 2.

Verifying that each operational cooling unit operates for at least 15 minutes.

c.

At least once per 18 months by verifying that each cooling unit starts automatically on a CCAS test signal.

Add a new paragraph to the Bases for Section 3/4 6.2 (page B 3/4 6-4) as follows:

Service water, chlorination is performed during containment cooler surveillance to prevent buildup of Asian clams in the coolers when service water is pumped through the cooling coils.

This is performed when service water temperature is between 600F and 800F since in this

~

water temperature range Asian clams can spawn and produce larva which could pass through service water system strainers.

Copies o'f the license amenoment, our evaluation, and the Federal Register Notice for this Technical Specification change will be sent to you when completed.

Sincerely, Thomas M. Novak, Assistant Director for Operating Reactors Division of Licensing cc: See next page
