SUBJECT:
RESPONSE TO TECHNICAL ASSISTANCE REQUEST - SS&D REVIEW In response to your memorandum dated January 5, 1994, we have reviewed the technical assistance request from the State of Arkansas for assistance in j
performing a device evaluation.
Enclosed is a list of questions / concerns that the State should consider during their review of the product evaluation.
In your memorandum, you requested that we submit a package of reviewer guidance documents including ANSI-ISO references. We have on several occasions provided this guidance to Lloyd Bolling, who periodically sends this guidance to the Agreement States.
We have ordered additional ANSI standards, and will forward them to Lloyd as soon as we can.
We have suggested that the State obtain specifications for Torlon so that we can update our technical reference files.
Please request that the State send us a copy of these specifications once they receive them from the manufacturer.
If you need any further assistance, please contact Tom Rich of my staff at 504-2511.

During review.of the gas analyzer, several concerns were identified that need to be addressed.. They consist of the following:
Our policy is that general. license products be tamper resistant.-
We do not consider standard socket head cap screws ~as tamper resistance. Allen wrenches are common tools and can be easily obtained.
- In order to determine whether or not the. device will maintain integrity during normal conditions of use, and withstand the environment in which:it is designed, the State needs to obtain-specifications on.Torlon from the applicant.
The minimum specifications for.Torlon that~ should be evaluated against the intended use of the-product are the temperature range, humidity range, corrosion resistance, and effects of beta radiation.
In particular, the effect of ammonia on Torlon.
In addition,'if applicable, a check should be made to ensure that any cleaning fluids or lubricants used during cleaning or maintenance of the device would not degrade the components of the device.
Additional information is needed as to how the source is held.in place. The drawing indicates that a set screw is used to hold the source in place. However, no information was provided as to what type of screw this is and whether the design of the screw could cause.a breach of the source. The State should confirm that during production of the device and the operation of tightening of the screw will not cause a breach of the source.
- How are the labels " permanently attached?" Will-the plastic label withstand the-ammonia or other concentrations that may be processed through the device?.Does the manufacturer warn against using any cleaning fluids or agents that will degrade the label? Does the manufacturer suggest use of a cleaning fluid or agent that would interfere with the integrity of the label? Do the labels meet the applicable
. Agreement State requirements to NRC's Section 32.51(3)(i), 10 CFR Part 32.
Was a drop test performed? If so, what are the test procedures and the results of the test (s)?. How does the manufacturer justify the statement, "the cell has been constructed to be extremely durable and capable of withstanding incidental abuse, (such as being dropped, hit accidentally with tools, etc.,)."
How is the device mounted to the enclosure?
Is the mounting hardware tamper resistant?
