Subject:
Commonwealth Edison Company Prompt Public Notification Systems Status of Installation and Initial Testing Dresden Station Units 1, 2 and 3; Quad Cities Station Units 1 and 2; Zion Station Units 1 and 2 NRC Docket Nos. 50-237/249, 50-254/265 and 50-373/374
, p f(g. j Refereb$el (1):
L. O. DelGeorge letter to J.
G.
Keppler dated January 27, 1982.
Dear Mr. Keppler:
Commonwealth Edison has notified your staf f informally that the Prompt Public Notification Systems required by 10 CFR 50.54(s)(2) for the emergency planning zones (EPZ) around Dresden, Quad Cities and Zion Stations were installed and an initial test (see Reference (1)) performed by February 1,1982.
The purpose o f this letter is to document our schedule for remedial action to correct oeficiencies identified as a part of the initial testing.
This report addresses only those fixed siren locations that have been added within the subject EPZ's to fulfill the requirements o f l
Sirens that have been in use by cities or towns within the EPZ 's f or civil defense, fire alarms, etc. and which are to be used as part o f the prompt notification system were assumed operable because they have already been tested by the local users.
For the fixed sirens added to complete the public notification systems, all sirens were successfully tested locally verifying the operation o f each siren (i.e. local actuation - growl test).
As was indicated to Mr.
W.
Axelson of your staf f during the week o f February 1,1981 certain of these siren locations did not indicate an actuation as a part of the integrated system operability tests performed between January 29, u.id February 1, 1982.
These
/
(
.qaoso3s' res 2 21982 t
F failures are judged to be a ttributaole to the radio control portion of the units; that is:
1.
Encoder trouble at the remcte control location.
2.
Signal level at the output of the encocer or audio input to the base station radio.
3.
Signal path resulting in low signal level at the receiver.
4.
Receiver antenna trouble.
5.
Receiver trouble.
6.
Decoder trouble.
7.
Wiring problems from the decoder to the siren controls.
In order to assure future reliable operation of all siren
/ locations, it is our intention to check the radio controls at each V siren location whether or not the siren failed on initial test.
Using Whalen Engineering personnel assisted by Commonwealth Edison Company personnel to do the radio checkout, the following is the sched11e for the work.
Zion Station 27 locations - Begin 2-15-82, finish 2-23-82.
Quad Cities Station 64 locations - Begin 2-24-82, finish 3-12-82.
Dresden Station 60 locations - Begin 3-15-82, finish 4-2-82.
If it is determinea that a revision is necessary to a particular siren location (e.g.:
relocate an antenna), this work will be initiated as soon as the requirement is identified.
The revision work will progress concurrent with the overall radio control checkout and the revision will be retested af ter it is complete.
Correction o f all deficiencies to the systems will be completed prior to June 1,1982.
We will advise you periodically before June 1,1982 o f the 3
status of these activities.
We will also attempt to provide any
O
_3 information made available by state and local authorities relative to siren coverage effectiveness tests to be performed later this year, as oescribed in Reference (1).
To the best of my knowledge and belief the statements contained herein are true and correct.
In some respects these statements are not based on my personal knowledge but upon information furnished by other Commonwealth Edison employees.
Such information has been reviewed in accordance with Company practice and I believe it to be reliable.
If you should have any questions on this matter or other related information provided previously please direct them to this o f fice.
Very truly yours, L. O. DelGeorge Director of Nuclear Licensing cc:
