Dear Mr. Crow:
SUBJECT Update of Descriptive Information Refere.ces:
- 1) Letter, H. Paul Estey (ENC) to W. T. Crow (NRC),
dated June 22, 1979, with enclosure.
- 2) Letter, W. T. Crow (NRC) to W. S. Nechodom (ENC),
dated September 26, 1979 As requested by Reference Number 2, above, Exxon Nuclear Company, Inc., herein submits descriptive information pertaining to facilities at its Horn Rapids Fuel Fabrication Plant. Similar information will be submitted on future facilities at appropriate future times.
Attached is a November 1979 version of the Horn Rapids Plant Site Plan which shows that facilities identified as item numbers 1, 2, 3, 6 and 11.1 (see Reference Number 1, above) have been completed.
Item Number 1 - Office Building Complex Addition A 60 ft. x 200 ft. addition has been constructed on the northwest corner of the Of fice Building Complex. The addition is concrete block constructica consistent with the rest of the Complex.
Item Number 2 - New Process Chemical Waste Storage Lagoon A 242 ft. x 289 ft., 8 ft. deep lagoon has been added to the I'rocess Chemical Waste Storage Lagoon System. Each of the four lagoons of this svstem have been sealed on the bottom and all sides with an impervtous liner to prevent leakage of the lagoon contents to the groundwater.
The liner consists of a double layer of impervious material separated by a layer of sand. A system of sampling tubes

$Q t
is installed in the intermediate sand layer to provide sampling capability between the liner layers to permit detection of leaks in the first barrier.
Routine monitoring of the integrity of the upper liners will be accomplished by drawing a vacuum on each group of the "between-liners" sampling heads at least quarterly.
In the event that a significant amount of liquid is pumped from any sampling head (s), the liquid will be analyzed for fluoride content (a reasonable indicator).
If such liquids contain mare than 3 mg/2 of fluoride, an investigation will be initiated.
Investigations will incluo :
a)
Chect-the integrity of the bottom liypalon liner of affected lagoons for lagoons numbers 1 and 3 by activating sampling lines (4 for each lagoon numbers 1 and 3) located between the bottom Hypalon liners and the original Petromat liners of these two lagoons; or
'c '
Checking the integrity of t S-bottom Ilypalon liner o f lagoon number 4 by sampling the 3 dry wells associated with the 3 " French Drains" located under the botuom liner of this lagoon; and c)
Making maximum use of the lagoon test well system.
In the event that a significant leak in an upper liner is detected, repair of the liner will be scheduled and completed.
- dditional test wells have been provided around the Lagoon System, bringir.g the total to thirteen (the test well locations are shown on the attached Site Plant). The cur at action levels and actions to be taken based on samples taken from these test wells are des-cribed in Section I-5.1.6.4 of Document Number JN-C for our existing license, and proposed action levels and actions to be taken are described in Section 3.4.4 of Document Number XN-2 for our license renewal application.
'he action commitments described above will be inserted into our
.icense recew-1 application (Document Number XN-2) when it is upd.ned.
Item Number 3 - P.I. Tool Examination Facility A 32 ft. x 40 ft. single story, steel frame and siding structure anchored to a concrete floor slab has been constructed to house an operation involving maintenance and calibration of instruments and tools used by Exxon Nuclear in fuel examination services provided to nuclear power plants. As such, these instruments and 'ools are occasionally contaminated with mixed fission prod cts.
AD;copriate facilities and areas within the building are controlled tom radiation g'.G..O [)
s.
s protection purposes in accordance with Exxon Nuclear's standard practices, and the exhaust air from the facility is liEPA filtered and continuously sampled. This facility, as well as operations conducted therein, are liceused by the State of Washington.
Item Number 6 - Temporary (Evaluation) Laundry Facility This facility will be operational in November, 1979, in accordance with License Amendment Application dated August 27, 1979, as supple-mented by letter dated September 19, 1979, and License Amendment Number 20.
Item Number 11.1 - Maintenance Building A 100 ft. x 125 ft. single story, steel frame and siding structure anchored to a concrete floor slab has been constructed to house non-radioactive maintenince activities that had previously been housed in the UO, building and sovellite trailers.
No operations involving radioactive materials will be conducted in the Maintenance Building.
Sincerely,
