Dear Mr. Crow:
SUBJECT:
Update of Descriptive Informatio'n
References:
- 1) 'Let'ter, 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 inform.stion pertaining to facilities at its llorn Rapids Fuel Fabrication Plant. Similar information l
4 l
will be submitted on future facilities at appropriate future times.
Attached is a ' November 1979fversion of the Horn Rapids Plant Siie
~
i l
Plan' which shows that f acilities identified as item numbers 1,' 2,
~
t 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 l
block construction consistent with the rest of the GtimplexJ Item humber 2 - New Process Chemical Waste Storage Lagoon A 242 ft. x 289 ft., 8 f t. deep lagoon has been added to the Process Chemical Waste Storage Lagoon System.
Each of the four lagoons of
. this system have been sealed on the bottom and all sides with an impervious liner to prevent leakage of the lagoon contents to the Eroundwater. The liner consists. of a double layer of impervious material separated by a layer of sand.
A system of. sampling tubes 49 AN AFFILIATE OF EXXO. CORPORATION 8004000112

J 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 qua.rterly. In the event that a signif t' cant 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 more than 3 mg/2 of fluoride, an investigation will be initiated.
Investigations'will include:
a)
Checking the integrity of the bottom flypalon 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 b)
Checking the integrity of the bottom Hypalon liner of
~ 1agoon number 4 by sampling the 3 dry wells associated
. with the 3 " French Drains" located under the bottom liner of this lagoon; and c)
Making maximum use of the lagoon tesd well sy, stem.
In the event that a significant Icak in an upper liner is detected, repair of the liner will be scheduled and completed.
Addit'ional te-t wells' heve been provided around the Lagoon System, bringing the total to thirteen (the test well locations are shown on the attached Site Plant). The current 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 Docmnent Number JN-2 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.
The action commitments described above will b'e insefted into our license renewal application (Document Number XN-2) when it is updated.
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 tools are
~
occasionally contaminated with mixed fission products. Appropriate facilities and areas within the building are controlled for radiation I

protection purposes in accordance with Exxon Nuclear's standard practices, and the exhaust air from the facility is KEPA filtered and continuously sampled. This facility, as well as operations conducted therein, are licensed by the State of Washington.
Item Number 6 - Tempdrary (Evaluation) Laundry Facility This facility will be operational in November, 1979, in accordanice with License Amendment Application dated August 27, 1979, as sdpple-mented by letter dated September 19, 1979, and License Amendment Number 20.

Item Nttmber 11.1 - Haintenance Build h A 100 ft. x 125 f t. single story, s : eel frame and siding structure anchored to a concrete floor slab his been constructed to house non-radioactive maintenance activities that had previously been
. housed in the UO building and satellite trailers.
No operations 2
involving radioactive materials wi?.1 be conducted in the Maintenance Building.
