@c Silver Spring, MD 20910 Gentlemen:
sw:
An administrative amendment to SNM 777, docket 70-820, is respectfully requested.
This amendment provides clarification of the language now in the Health Physics Section (Section 400) to assure compliance during planned shutdown of ventilation equipment.
While planned shutdown is allowed, it is the responsibility of ope' rating management to obtain prior clearance, and the responsibility of Nuclear and Industrial Safety to provide adequate precautions.
These responsibilities are defined in detail.
This added paragraph constitutes only a minor administrative change.
A check for $150 is enclosed as required by your revised license fee schedule issued February 28, 1978.
Should you wish any further information, we will respond promptly.
Very truly yours, UNITED NUCLEAR CORPORATION C.

SUBSECTION:
404'- Facility and Equipment Pcquirenunts Supersedes 1-17-75 404. Facility and Equipnent Requirements 1.
Zoning The facility shall be zoned to define contandnation control areas and clear areas. Protectiva clothing or special clothing, shower and change facilities shall be provided for use in the contamination control area. A sink and alpha survey meter or hand nonitor shall be provided for personnel exiting contamination control areas.
2.
Ventilation Air ficw shall be from areas of lower to areas of higher contamination.
Hoods, glove boxes, or local exhaust will be used to cont' ol contamina-r tion and airborne concentrations.
A unit or system of units may have the exhaust fans turned off, pro-vided that hood doors are closed, and no operation is in progress in the unit or system. Repairs, cleanout, and/or decontamination may be permitted with'the fans turned off, provided written approval is granted by. the Nuclear and Industrial Safety Department.
Such clear-
'ance will include nonitoring requirements for airborne radioactivity and required corrective actions if allowable levels are exceeded.
Ventilation equipment will be installed that is suited to the operations being performed, including in such considerations the specific activity of the uranium and its relative dispersability. General guidelines for ventilation and air novement requirenunts are:
2.1 Class A Ventilation Furre Hoods: Minimum 100 ft/ min face velocity.
Used for control of funns where nodest quantities of airborne uranium are generated.
Typically, these hoods might handle uranium primarily in solution form.
2.2 Class B Ventilation Ircal Exhaust: Minimum 150 f t/ min spot velocity.
Spot ventilation used at locations such as sampling ports and product take-off parts where the need for air control is nomentary or of low frequency,
and generation of airborne material is limited by equipmnt design.
2.3 Class C Ventilation General Purpose Hoods: Minimum 150 ft/ min face velocity.
Used for material transfer and sindlar operations where generation of air-borne material is limited.

desirable during certain process steps involving active.or potentially active generation of airborne contamination.. Such hoods will fre-quently include gloveports and will normally be closed during produc-tion operations.
