OPERATING LICENSES DPR-57,JPE-5 EDWIN I. HATCH NUCLEAR PLANT UNii5 1, 2 NUREG-0737 ITEMS II.F.1.1 AND II.F.1.2 m

Gentlemen:

Yourf letter of October 5,1981 requested that any technicalMeviations from the stated positions of items II.F.1.1 and ID.T.l.2 pf NUREG-0737 be submitted for review.

Further, it was ' requested that sthe need ~ for any

?

extensions be brought to the NRC's attention.

A request for extension of s

the implementation. schedule for these particular items was included among other NUREG-0737 items in a request dated November 4,1981.

This letter will not, therefore, further address a request for extension.

We have, however, determined a technical exception to the state'd "NUREG-0737 positions on these items.

(

Item II.F.1.2 required provisions for effluent monitoring of radiciodines for the accident condition.

It was stated that the design of the systems for the sampling of particulates and iodines shoe'.d provide for sample nozzle entry velocities which are approximately isokinetic with expected induct or instack air velocities.

Georgia Power Company hereby

~

• requestsexceptiontothisrequirementforthereasondescribed_herein.\\

The error associated with anisokinetic sampli6g is neglihible for small particulates.

Releases of radioactive iodines and/or particulates from the -

E. I. Hatch Plant take place through either the off-gas s' step stack or the a

j reactor building exhaust vent.

Before being released, theses effluents Dass through HEPA filters which trap large partic01ates.

Sampling will. take place downstream of these filters.

Although thetsample. will bestakerPat 'a constant flow rate irrespective of the flow through the duct or. stack, no significant error will result because of the particulate size. distribution resulting from HEPA filtration.
