NRC INFORMATION NOTICE 96-53, SUPPLEMENT 1:  RETROFIT TO AMERSHAM 660          
                                             POSILOCK RADIOGRAPHY CAMERA 
                                             TO CORRECT INCONSISTENCY IN 
                                             10 CFR PART 34 COMPATIBILITY

Addressees

All industrial radiography licensees.

Purpose

The U.S. Nuclear Regulatory Commission (NRC) is issuing this information
notice to inform licensees that the retrofit to the Amersham Model 660
Posilock radiography camera referred to within Information Notice (IN) 96-53
must be completed before January 1, 1998, to maintain 10 CFR Part 34
compatibility.  It is expected that recipients will review the information for
applicability to their licensed activities, and consider actions, 
as appropriate, to avoid problems.  However, suggestions contained in this
information notice are not NRC requirements; therefore, no specific action nor
written response is required.

Description of Circumstances

On October 15, 1996, NRC issued IN 96-53, "Retrofit to Amersham 660 Posilock
Radiography Camera to Correct Inconsistency in 10 CFR Part 34 Compatibility,"
to make licensees aware of a scenario where the Amersham model 660 Posilock
radiography camera would not pass the horizontal shock test, as required by
Part 34, and of a retrofit to the Amersham Model 660 Posilock radiography
camera, to correct that problem.  Appendix A contains a copy of IN 96-53.

Discussion

To allow licensees sufficient opportunity to request and install the retrofit,
units not containing the retrofit will continue to be approved for use through
December 31, 1997.  Effective January 1, 1998, units not containing the
retrofit will no longer be approved for use.  Affected cameras may be checked
for completed retrofit during any inspection.  Cameras with the retrofit will
be deemed to meet the requirements of 10 CFR Part 34.
