an analytical reagenta Mallinekrodt has requested Comission approval to perform the h 1 of Con-work pursuant to the provisions of Article I, ParagrapDuring the est tract W-lh-108-eng-8.
being administered by New York Operations Office, a similar requ t time has was approved, but all of the material so process his material.
It is proposed that MCW will procure m the open market (under 3 - commer,cial grade - to produceConsiderat proper license) sufficient UO200 pounds of metal in th The metal MCW would reim,

> Sefety Presetatidas. Most of the problems that arose in designing the plant stemmed from safety require-ments. One problem that had to be 4
considered is leakage of UF..
If any of the fluoride escapes into the air, at-mospheric moisture is enough to hy.
drolyre it. contaminating the air with HF aml UO Fs. All connections have s
to he checked carefidly. md the ex.
haust air goes through special dust col-lectors.
This ensures removal of uranium dust, and facilitates product recovers.
Any dusty operation, e.g., grinding and screening, is carried out in dry boxes. These are independent of the general room ventilating ssstem and are operated at reduced pressure. In this way,if a leak occurs, air enters the box instead of escaping from it.
[ j Another safety measure is in wash-ing the workers' clothing. Uniforms may be prewashed by the company be-fore being sent out for cleaning. Ifthe wash water is relatively high in uranium 4
content. the clothing is washed again.
The uramum is then extracted from the w ater.

pomt ud view-regardless of the pro-
{l duction load, says the company. in-e surance enmpanies seem to agree, smee Mallint hrodt's atomic fuel plant is covered hs the first policy issued by the 9
Nudear Energy Protective Association of Hartford.
> Room fee Growth, A firm com-mitment made by the company is that it will meet the demand for atomic fuel no matter how large it becomes. The Hem.itite plant has a lot of elbow room.
[i It's on a 1% acre tract with good road and rail larihties, plenty of water, and well above the highest flood level.
Ami t h it the company plans to move ahead m this field is confirmed by President Joseph Fistere, who says,
- h. r 1942, when Mallinckrodt pio-nected l4rge scale production of ura.
nium, we hne continued to expand our mterest m this field. We have enthu-
{,
metically entered into the production of atomic fuel material since this is a logical extension of our past interests, and gives us the opportunity to apply acquired technical skills to the nr scartor program."
