PROBEECS lilTl!,TUE !!FS-4 (!!AC-IE) CASK This refers to our 10/1/80 telecon.' By now, weshould have a fairly good overall general picture of the history of events surrounding 'the operational shiprent difficulties with the subject cask durinsthe past six months.
I suggest that questions arising froa these difficulties could fall into several areas, as follows:
1.
Soccific Shipr.ent Oacstions a.
Conn-Yankee to Gattelle Shipn2nt i
. niscalculation of hcat load
. nodification/renlacemnt of drain ' valve e
. provisions for loading /contain:nent of failed fuel i
b.
Unloadino Conn-Yankee N_ tor.cnt 'ai Pattelle_
l
. -events surrounding actively release upon unloading the failed fuel
. adecuacy of Batte.11e's procedures prior to shipment of cask to Cyster Creek c.
Cyster Creek
. why uasn't problem with excess cask internal activity fvTly acknowledged between all parties (Battelle, Oyster Creek, and IMC) before cask was sent to San Onofre?
d.' San Oncfre_
. adequacy of, health physics procedures for receipt and sanpling of cask
. what to do next with the cask?

2.
Cash Quest,fons_
. Is Certificate of Compliance adequate with respect to failed fuel containment requirements?
1las drain valve rodification authorized and appropriate?.
Is this problem relevant to earlier history of. problems with this cask " family"?
'~

3.
Generic Ouestions Th'e system of controls, respan,sibilities and nanage:2nt relationships between the utility and the contractor uho provides leasing equipmnt and services iny'olving s'pcnt fuel casks.
The adequacy oficalth physics procedures of licenses during unloading /
loading of casks.
/.t least three regions are directiv involved in the specific shipnent questions, with the fourth (Region II)~ certainly on the mrgin for all the questions.
'In the interest of moving ahead on this problem, I have requested that Region I take the lead in conducting a coabined/ coordinated investigation on these I ask probicas, drawinc cn the assistance as needed from the other regions.
that this investigation be assigned a high priority and that we be kept advised of its progress. 1,e have discussed this natter with X005, and they are utiling to provide any 6ccessary investigation assistance. !!c have also discussed this catter with C. E. liacDonald, li!!SS, and they also are willing to provide assistance l
on liccnsing questions.
