Pusuant to- 10 C73 2 71' 4 (a)(3), the petitioners' sententions of April 13, 1979, relative to a eyent fuel meltteva (SIM) that is possible at ACNGS, are herewith amanist and 8nfized8* .

1. Tuther rubstantiaties of the yestslatism of a SIM at AGNG3 is the doeuaxs prepaLred fer the USERC, " Spent Tuol Heatup 7en evisc Less of Vater During Storags8 (3U33G/CL C6k9 SA:iD 77-1371. This study, which supports maar of the fi241xgs of the WEST Ger=ma lepert 13 290, Angsst,1976, someus that the yeesibility that a 37M ses11 eeen uless sigxifisant Masign modifications 8 er 8effsetive emergsmay eeutarzessures" are instituts&. 3eththeNU25G/Ch C6h91sprt and the first and second Vest Germaz 2eyerts 13 290, August 1976 and November 1977, de met negate the yeesibility of a S2M, but sinyly rely, in such an event, that plaat persommel could pressed with eeunternessues in reylasement of eselant to datar a SIM. It sammet be debated that such a possibility of a 32M saa essu.

As previously stated 12 ear sententions of April 13th, 8Aside frem the mena=4 su et sabotage, huan amt mechanisal error, termadees amt earthqsakes causing a spent fuel yeel meltteva, there is an alarming posibility of a roaster maltteva preelyitating a fuel nel meltdeva.

This is a yessibility because the eseling systems of the roaster and the spat fuel yeel are lished together.* 7enevizg sush scenaries, there is every pebability that radiation deses veult reach such levels that plant persemasi vesli be sempned to evasuste ami abandex the roaster. Sizes the caeling system for the syest fuel pel (37P) beoemas mem-famatiemal, the S7P rapidly heats sin amt yreeeeds to beildeva ama meltteva sassing massive releases of lethal radienstivity. ,

~

Neither the applicant mer' the staff have adequately esasitared the aests in terms of health as ven, as the seezemis sests of a yeesible aseident in th ex-site stomage of syest fuel.

The Timal Supplement to the 733 (EU23G-0470) fails to discuss the pssibility of a S2M ami what measures vesis be instituted to provsat such escurrames. Neither the ayylisant mer the staff have taksa inte seasideraties the requisita of plant design modificatism to help imped.e a SIM as resemmended by 3UEEG/CLC6h9

2. Additionany, the syylisant has met dealt adequtely with th additiemal hazard involved ix the yessible storage of spent fuel is eleser yrszimity than originam plammed. Hammfae-tuers of high-tensity storage racks which significantly imersase existing storage sayability aise have met dealt with this additiemal hazard. I2 Jazuary 23, 1979 Prospectus of Texas Utilities Co. , it stated, 8...thare vill be en-site storage sayasity for spent fuel to asses-medate the operation of the uits ama this storage sayasity eam be ixeressed if needed."

While yetitiemars de met have assess te e, earrant EI&P Prospetus, there is me desht AC3GS vin be seastrusted to have a senatant imersment storags sayasity.

If the methat to be used for 12ersasing sseh storage sayasity is by the sse of high-Lensity storage rasks, this particular qsestien needs to be addressed by the syylisant.

3 The- spent fuel melttava esatsation has already been asseytet by various Atomie amt Safety Lisemetzc 3 marts en other Deekets. Inslosed is a list of some musisar plant heariscs ami their rosyestive 3eekst Yumbers vhare the sentantism has already boom asesytet as valid amt yestiment ts hearing preseedings. Alse emelssed are sayiss of two sets of sententions, forma-lated by an esiment muelear seientist with rztensive lengsvity experienee W.th the Atente Zaergy Commission amt the suelear 12dastry in sommercial amt military reaetors, that have been eAyyliaant's terminolog7 re 8Ayyliaant's 2sspass to Texpirg's Amends 4 Cententions", hly 10, 979-p((q { g ]y j 79 0050 M 6

Wat is eyes more signifisant to the validity of this sententism is the fast that the ASL3 en ens of the Deckats,12 assept12g the sententisa, vent further and isesed its eva suse12st qseettoms relevant to a S2N to be disasseed 12 the hea 12g preeeedings.

Se overriding eensara of the ayylisant ama the USSEC should be safety.

It would ayyear to be s. great ixseagruity if the esent fuel meltdawn sententiens that are already asseyted by the US33C is ammeress other Deeksts, met be seasidered apsesite to the Alleas Creeic HGS heariscs.

I. Introd uc tion Nuclear power plants produce extremely large amounts 'of radioactive substances as a by-product of operation --- substances which emit harmful nuclear radiation and which must be absolutely confined to containers and prevented from escaping into the bio-sphere (the human environment), in order to avoid exposing humans and other life to high levels of radiation and the high risk of cancer and other diseases that would result. These substances are considered as nyclear waste that must be safely disposed of, e.vcept possibly the by-product plutonium, which is a nuclear fuel material that can be further used, but which is also a highly toxic radioactive substance. Even if plutonium were used to fuel nuclear power plants, however, a substantial residue of it would still remain in the waste material, thereby adding to the waste's

~

toxicity. It was criginally intended to dispose of high level radioactive waste by placing it deep underground, for isolation from the biosphere in special facilities called teologic reposi-tories". However, there presently exist no such facilities for permanently and safely disposing of nuclear waste; nor is there any assurance that such facilities will exist in the next twenty years, or ever will exist, due to technical problems of assuring isolation of the waste for the hundreds and tens of thousands of years that.will be required for the material to decay to safe levels of radiation. As a consequence, high-level radioactive waste and plutonium is dangerously accumulating in storage pits at nuclear power plants and other places in the form of scent fuel rods (to be described shortly). These " spent fuel storage' pits", though each is enclosed in a building, are creating an

34' Appendix 2 Rasmussen Report's Implicit Strontium-90 ru Release Figure for a Spent Fuel Storage Pool Accident: 2000 curies.

The Rasmussen Report estimates that 1.88 x 10 curies of

" alkaline earths" radioactivity escapes one third of a core load of spent fuel which a has aged for 60 days, and that l's of this rad ioactivity escapes the build ing (Ras. Rpt.,

app. I, p. 103-10ft ) . Alkaline earths consists of Barium-140, strontium-89, and strontium-90, with half lives of 12.8 days, 50 5 days, and 29 years, respectively. The NRC's environmental impact statemen[ for spent fuel (NURIO-0404) tabulates the quantities of these substances per metric ton of spent fuel.

At time o f discharge from the reactor (p. G-ll):

Ba- 140 -<- 1.72 x 10 Ci/MTU Sr 89 ---- 9.47 x 10 5 ci/MTU Sr-90 ---- 6.4 x 10" ci/sTU.

The mass of fuel per assembly is .45 MTU (NURSC-0404, p. G.-5):

and one core contains 193 fuel assemblies: hence 1/3 of a core equals 65 assemblien. From those data one can calculate the release fraction of alkaline earths and then th e raft release quantity of strontium-90. ?Ie can compute the release fraction (F ) implicitly assumed in the Rasmussen's estimate from the following equation fo r radioactive decay: ' 7 5 x .arx ss x 1 7 axio'i $ $$ en n/e y g.a/i " ls a %

Solving for F 7, F72./ A, or roughly 105 Therefore, the asured x2 assumed strontium-90 release from the storage pool building (assusmed a (assumed in the Ras. Report) is
