SUBJECT-LETTER FRCM LCGISTICS l'A :AGEMErlT 1 ;STITUTE Attached is a letter from Logistics "anage.,ent Institute offering to come over to discuss '.<ays we could use their experience in r ainte-ninre procedures to help i;RC estatlish peccedures for nuclev po.ter piants.
The Logistics Management Institute has for many years been the Department of Defense cilsulting fica providing advice in the crea of logistics canagement.
I have sugrested the follouing:
a.
B':Cullcugh or PedricP. (Logistics Manage. rent Institute Presi-dent) call Bob Minogue to determine whatner there might be any interest.
b.
That someore in Denton's of fice - when they get a char.ce af ter TMI pressure has been ceduced - examine tha attached letter and, if it looks interestinE, contact I'cCuilcugh.

Dear John:
Doubtless, you are swamped with input and inquiries relative to Three Mile Island.
I don ' t wan t to add to your problems, but just nake a couple of points and a suggestion that night be helpful.
I take it as a given fact that nuclear plants have been designed with the best engineering that radern technology can provide, to high safety car; ins, and to very high levels of redundancy. The computer driven con-trol sys tems employ state-of-the-art technology and function as planned. So key issues are not the quality or the fail safe character of the design.
.kother Rasmussen-type stuly at this time would see : to be of little help in dealing with the instant problea.
" c; is a najor ccncern is the intentional violatica o f ':RC regulations in continuing to operate the plant uhen the lack of the three auxiliary cooling pucps in the prinary cycle (I am going on the press reports, now) had to be taken out of service.
Certainly steps ha,.e to be taken to assure corp!iar.cc with the safety regulations, but a larger question is the conditions that r.c have_ contributed to the problem.
'ii ; 1ere at D!I have wondered whether the naintenance policy at these p?ints light be exanined. This mainten1nce factor encompasses :
o Sparing of parts for repairable compc n t s, e. g., p ump s.
o The level at which parts are spared.
While sparing at a very low level, i.e., nuts and bolts, is the rost economical, it implies a higher level of maintenance tanpower and cuch longer out-of-service tines associated with equipment repair.
o Maintenance nanpower: predictable requirements based on sparing philosophy, inventory of spares, and equipment reliability charac teri s tics.
'~
My inpression is that the equipment caintenance of these plants may not have been dealt,;ith in the sa:e degree o f thoroughnes5 as the design and reliability issues. Analytic tools exist today ;hich eere not available just a few years ago.
Le have de'. eloped tcols for the DoD ehich are now routinely used to budget for naintenance anpo. cr and material. Their use is predicated on their pro.ed ability to relate accurately such expenditutes 7905160/

The lionorable John F.
Ahearne Pag 2 12 April 1979 to the operaticnal availc' ility of end itens.
'47 thought is that if *.he plants are not' adequately nanned and spared wtth respect to raintenance, situations such as those at T4I nay reoccur.
The Ni:C needs to kno., lihat are adequate IcVels and nay tant to consider al te rnatives with respect to passible standar1; and regulations in this area.
When you get a chance to take a breath, I would like to visit ycu with some of my associates to discuss the natter. He think L.'4I has some uniqua capabilities '.ehich cay be of service t o t h e ?.T.C.
