TID-7016 In two moent mance to me, one dated n.c h

1,1966, conoeming an appliostion fmn NLMDC and the other dated n=ammhan 14, 1966, concerning an application face UIC, you saggested that we infom these licensees that Figures 13,14,15, and 16 of TID.-7016 appear to be nonconservative based on recent wout by H. K. Clar* (DP 1014 and Stockholm Pimper SM-70/31) and others which indicates that the specified TID-7016 criteria, in some oness, enamed the minismsa critiaal v=1===.

This infomation appears to bd of geneml applianhility since seny SIM liaaneses use TID-7016 to justify fmm a nualmer safety standpoint at least portions of their opemtions. The m fore, all licensees who may be affected should be pawided with this information without undus delay, mther than in a omeo-by e basis.

Your menos do not indiente whether or not the above situation presents a real nuolaar safety publem in that they did not identify the situations where the TID-7016 unne1A be nonconservative. This situation, of oota w,

should be handlad in a menner consistant with the seriousness of the matter.

If you detemnine the continued use of the above specified TID-7016 I*1gures,

(

as may be approved in a

==h==* of SPM licenses, might result in socidental J

aritlaality in certain cases then you should inmediately proceed to zwiau the license films to identify the situations whout this annald coeur so that

=adified safety limits een be imposed for those cases. On the other hand, if you detemine that the matter is not of sufficient seriousness to warrant this type of action, then an appenpriate letter should be prepared for the infommation of SIM licensees which would identify the probles and specify 4

the instances where the TID-7016 criteria are nonoonodrvative in order that the licensees may take such infomation into account in preparing applications 5

for license amendments and raraumle.
