Modification to Request for an Extension to the R-63 Reactor License.Re: a.Arendnent No. 6 and Change .' o . 2 to License No. R-63 dated 16 March, 1974, Dccket No. 50-111.

b.Letter from Dr. T.S. Elleman to Director Operating Reactcrs Branch dated 15 January, 1979, Docket 50-111.

c.Letter to'r.J.R.Echann^n, Jr., frcm '4r. Robert Reid, Chief Operating Branch 44, Occket SC-lll.

Reference 3 above changed the status of the R-3 reactor to " possess, but not operate" from an cperating utilization facility.

This amendment also stipulated the radiation detection systems to be maintained.

Reference b above requested an extension of the current R-63 license to February 1991 from 19 February 1979, and summarized our status regard-ing dismantling and decomissioning.

Reference e above acknowledged receipt of reference b and the con-tinuation of our R-63 license pending review of our request.

The R-63 license authorized NCSU to " possess and store up to 4.CO2 kilograms of ccntained uranium 235 ...". The irradiated fuel assemblies, a total of 3027 grams U-235 contained in 26 assemblies, have been shipped to the Savannah River Plant. DOE, Aiken, S.C.

The remaining four un-irradiated assemblies, containing approximately 567 grams of U-235, have been moved from the R-? Bay to the PULSTAR Bay where these assemblies will be stored ir. a three combination lock safe.

The purpose of moving these four assen'alies to the PULSTAR Say was to consolidate physical se-curity of the SNA in our possession. All R-3 reactor fuel has been removed from the R-3 Say.

The R-3 reactor biological shield with its contained activation products remain in the R-3 Bay.

This shield has a 2" steel plate cover-ing the reactor tank and each beam port is closed and locked by a three combination safe-type lock.

The R-3 Bay also has a Gamma Irradiation Facility which is under a license issued by the State of North Carolina.

• page 2 The radiation sensing devices of this f acility are connected to the Bay's evacuation horns. The R-3 Bay will be retained as a " Restricted Area" and controlled acccrdingly as in the past; i.e. Bay locked, per-sonnel access controll i and routine security checks.

The next steps are the preparation of a dismantling plan for sub-mission to NRC and the necessary budget action to obtain funding to implement the plan.

!* is requested that reference b above, anc cur R-63 license, be modified as folloas:

1.The R-3 Reactor area monitors and stack monitors currently re-quired by reference a above be discontinued. Basis:

All R-3 fuel has been removed from the R-3 Bay and the Gamma Facility detection system will be active.

2.The daily air samples and .seekly smear survey in the R-3 Bay be discontinuac. Basis: See pl.

3.The B-63 license be amended to reduce the amount of S'"i author-ized to be possessed to 567 grams contained U-235 from 4002 grams.

Basis: To retain the four unirradiated fuel assemblies.

4 The expiration date be axtended to 19 Febuary, 19e3 ir. stead of to 19 February 1981 as requested in Ref. b above.
