Director, Region I U.S. Nuclear Regulatory Commission 631 Park Avenue King of Prussia, PA 19406 Gentlemen:
United Nuclear Corporation, Fuel Recovery Operation, Wood River Junction, RI, operating under Special Nuclear Materials License SNM-777, presents its semiannual report of the quantities of radio-active material in effluents released to unrestricted areas during the period of July 1, 1978 to January 1, 1979.
The principal radio-nuclide released was highly enriched but unirradiated Uranium (greater than 90% enrichment in the U-235 isotope).
This report is provided in compliance with Title 10, Code of Federal Regulations, Part 70, Paragraph 59.
Airborno effluents were measured by continuous sampling of each exhaust stack.
Liquid effluents were measured at the final collection point.
No dilution factors were applied to effluents.
Conversion of radioactivity counting data into grams of U-235 or microcuries used the conservative value of 143 alpha disintegrations per minute per microgram, and the standard value of 2.22 x 106 disin-tegrations per minute per microcurie.
All releases were below the limits specified by 10CFR20, or by license conditions.
The attached tables summarize the required data.
Veery truly yours, UNITED NUCLEAR CORPORATION h,

Microcuries 20.22 33.35 Average Release Rate for Period Ci/ml/sec 3.599 x 10-26 5.806 x 10-26 Percent of Action Level 11.57%
18.67%
Percent of 10CFR20 (Rate) 7.30%
11.78%
NOTE:
Gaseous effluents are released from 5.3m height.
The values listed are the summation of 13 stacks (closely grouped in a 75 x 75 foot square) each sampled continuously.
Calculations are based on operations for 13-7 day weeks pc. quarter, maximum flow rates, and counting results.
Values are believed good for two significant figures.
- nominal composition:
U-234 1.01%
U-235 93.0%
U-236 0.2%
U-238 5.79%
