Dear' Dr. Mallett:
As requested by your letter dated December 27, 1989, enclosed is a report on the status of.open itemv listed in Inspection Report #70 0036/89004 (DRSS).
Please advise if firt. ier information i!. required.

i Status of Open Items - Inspection Report #70-0036/89004 (DRSS)
Open Item #70-36/89004 Posting of storage bins in incinerator area.
The criticality limit sign for the storage bins has been changed to limit storage to contaminated items with no significant uranium.
This will allow more than one item of this type to be stored in each bin.
Items listed in Section 11 of the Inspection Report:
02 - Review safety of operation of the older dewaxing and sintering furnaces.
We plan to install ultra-violet flame sensors on dewaxer #1 and furnace #5 in the old pellet plant (Building 255).
When the equipment in Building 254 is fully operational, only these units will remain in routine operation.
03 - Portable fire extinguishces should be inspected monthly.
One monthly inspection of fire extinguishers was missed after reassignment of duties within the Nuclear and Industrial Safety group.
The Health Physics Supervisor will routinely check to ensure that the fire i
extinguisher inspection is performed in a timely manner.
04 - Provide fire water system to upgrade fire suppression system.
A proposal for 200,000 gallons water storage facility was recently requested from a local design engineering company.
Our commitment is to have additional anhydrous ammonia storage capacity.
Use of water to fight fires will continue to be limited due to criticality safety considerations.
05 - Training for fire brigade members should be oriented towards hands-on fire fighting. The effectiveness of the in:truction should be tested.
Hands-on training is conducted in the use of portable fire extinguishers l
and self-contained breathing apparatus, alternated with classroom sessions, training films and drills.
We will work with local fire l
department personnel to ensure the effectiveness of this training, including testing where appropriate.
l 1:
i 06 - A dike to contain potential nitric acid leakage in the South Vault is f
l recommended.
l l
A concrete dike will be constructed to prevent a nitric acid spill from L
contacting organic materials. This will be completed by April,1990.

Page 2 Hematite Plant Licence #SNM-33 07 - Unneeded combustible objects should be promptly remcved from the manufacturing areas.
We will continue efforts to minimize combustible loading of the manufacturing areas.
Empty boxes and crates wfl) to promptly removed.
Also, aluminum pallets will be obtained to replace wooded pallets for necessary storage in these areas.
L 08 - Review micronizer equipment and operation for potent.lsi loss of containment of SNM material.
As ' stated in the Inspection Report, operation of the deronizw has not caused significant airborne contamination.
Blow buck of the system, however -does cause contamination on the inside of the hood, We have designed an experimental funnel shroud for better conthinment of blow-back in the new facility and will evaluate re'trofitting this into the older. areas of the plant.
We will continue to em6 tor airborne concentrations with both fixed and lap?1 air samplers, L
