SUBJECT:

REQUEST FOR ADDITIONAL INFORMATION - PROPOSED EXTENSION OF EXPIRATION DATE OF POSSESSION-0NLY LICENSE

Reference:

Peach Bottom Atomic Power Station, Unit 1.

By Amendment No. 6 dated July 14, 1975, the Commission amended Provisional Operating License No. DPR-12 to possess-but-not-operate status for the Peach Bottom Atomic Power Station, Unit 1 (Peach Bottom 1). In our related Safety Evaluation and Environmental Impact Appraisal we found that your proposed decommissioning plan involving long-term on-site storage of residual radio-activity was acceptable. In our July 14, 1975 Environmental Impact Appraisal, A we determined that " allowing the radioactivity to decay for about 50 years V will reduce the expense, personnel exposure, and the risk of potential environmental effects from the dismantling operation".

{ By letter dated November 24, 1975, you requested an extension of the expiration

' date of License No. DPR-12 from " December 24, 1975, to June 24, 1977, or until such further time as the Commission may deem appropriate". In our letter dated April 2,1976, we informed you that in accordance with 10 CFR Part 2.109, License No. DPR-12 was extended until we took action on your request.

The Decommissioning Plan for Peach Bottom 1 indicates your intention to retain the facility in a SAFSTOR status for a long term in contrast with your November 24, 1975 request for license extension.

We have reviewed your November 24, 1975 extension request, your May 19, 1975 Decommissioning Plan and your July 1978 Final Report and have determined that we need additional information to complete our review of your license extension request.

We need to know when you intend to remove the residual radioactivity from Peach Bottom 1 (dismantle /DECON) and, thereby, make the facility acceptable for unrestricted access. You are requested to revise your application for license extension to be consistent with your plans for removal of residual radioactivity.

l We are required by 10 CFR Part 51.20 to prepare an Environmental [ Statement (ES) for license amendments involving reactor decommissioning such as your request for an extension of License No. DPR-12. Therefore, please submit information, as outlined in 10 CFR Part 51.45(b), to us in order that we may develop an ES. A copy of the Draft ES (DES) for Humboldt Bay Unit No. 3 Decommissioning (Enclosure No.1) is provided for your information and guidance.

You will note that the Humboldt Bay Unit 3 DES includes a discussion of the fuel stored on site. Since there is no fuel stored at Peach Bottom Unit 1, that part of the DES would not be applicable. Enclosure No. 2 identifies additional information that we need to complete our evaluation of your license extension request.

Proposed Extension of i Possession Only License No. DPR-12 Docket No. 50-171 ,

1) Provide an updated inventory of radionuclides (current curie quanities) as previously tabulated on page 34 of your May 15, 1975 Decommissioning Plan. Include niobium-94, europium-152 and carbon-14 in the updated table.

2) Provide a second table that projects the radioactive inventory at the time you intend to remove residual radioactivity from Peach Bottom 1.

3) Provide an estimate of the deposited activity (contamination) as shown in Figure 3.11-2 of your Decomissioning Plan for the times indicated in items 1 & 2 above.

4) Identify any benefits that result from your proposed delay in removal of the residual radioactivity with respect to: -The methods that would be used in removing radioactivity; any reduction in the total person-Rem

, exposure to workers; and any reduction in the volume of radioactive I waste produced during dismantling. Provide graphs of gamma radiation exposure vs. time that workers would be exposed to when removing residual radioactivity.

5) Enclosure No. 3 (Letters from the NRC to Stanford University) states our present criteria for release of a facility to unrestricted access. Provide an evaluation of the predicted radiation levels in I buildings, rooms and structures relative to that criteria at the time i in which you intend to remove the residual radioactivity. Will any

structures meet Enclosure No. 3 criteria at that time without further decontamination?

Dear Dr.' Finston:

By letter dated' March 17,1981, we provided radiation criteria for' release .

of the dismantled Stanford Research Reactor to unrestricted access. That '

criteria specified Reg. Guide 1.86 for surface contamination and 5 micro Rem per, hour at one meter for reactor generated, gamma emitting isotopes. ,

l Since March 17, 1981, we have refined further our position with respect -

to relea,se criteria and have determined that radiation from gamma emitting iso, topes is also acceptable if the potential exposure to individuals is 1.ess than 10 mrem per year with reasonable occupancy assumptions. If you

.I wish to justify gamma exposure rates ,from reactor generated isotopes that ara greater than 5 micro Rem 'per hour, you should show that reasonable

~

~

occupancy of that area would be suffi,ciently less than 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> per. year, which would result in exposures of less than 10 mrem per year Sincer l

Dear.Dr. Finston:

By letters dated December 9,1977 and June 3,1980 you provided data on' .

the -residual activity at the dismantled Stanford Research Reactor. You further requested temination of reactor License No. R-60. - <

As discussed wi,th you, we have now determined the levels of radiation that.would be acceptable for release of the Stanford reactor facility

'I to unrestricted access. Enclosure No.1 provides that criteria. Enclosure ~

.; -No. 2 (Regulatory Guide 1.86) is also provided .for your information. . ,

-ThereforeJ we can terminate License No. R-60 when our independent surveys

.confim that you have removed sufficient residual radioactivity to meet t-the criteria of Enclosure No.1.

3 By copy of this letter to the NRC Region Y Office, we request that they -

complete a confinnatory survey when you notify the NRC that your facility '

is in compliance with Enclosure No.1 criteria.
