Commitment made by licensee stated in Report Details, paragraph 5.b.

Dear Sirs:

North Carolina State University is hereby submitting a corrected page to the PULSTAR l Annual Report for the period 01 July 1994 through 31 June 1995. The report had a typographical error on page 6 concerning the tritium levels released in liquid effluent from 01 October 1994 through 31 December 1994, specifically paragraph 6.7.5.f column (e) and item (g). Please update your files with the attached page.

Should you have any questions concerning this reply, please contact us.

Sincerely yours, A l M'

.rUtsrAR REAcmR ANNUAL REPORT 6 Revised 28 June 1996

. DOCKLT NUMBER 50-277 01 July 1994 30 June 1995 6.7.5f Radioactive Effluent-A. Lionid Waste (summarized by quarters)

1. Radioactivity Released During the Reporting Period:

(a) (b) (c)' (d)2 (e)

No. of Total Tot. Vol. Diluent Tritium Period Batches Ci Liters Liters Ci 01 Jul - 30 Sep 94 4 78 1.1E4 8.5E5 2 01 Oct - 31 Dec 94 3 13 9.4E3 2.0E4 11 l 01 Jan - 31 Mar 95 6 40 1.7E4 1.0E5 38 01 Apr - 30 Jun 95 2 32 6.8E3 2.0E4 29 (f) 163 Ci total activity released during this reporting period.

(g) 80 Ci of tritium were released during this reporting period.' l

2. Identification of Fission and Activation Products:

The gross beta-gamma activity of the batches in (a) above were less than 2 x 10-5 Ci/ml. Isotopic analyses of these batches indicated low levels of typical corrosion and activation products.

3. Disposition of Liquid Effluent not Releasable to Sanitary Sewer System:

All batches of 1(a) above when diluted by campus water (2.80 x 106 liters; the minimum daily campus intake) resulted in activity considerably less than 1 x 10 4pCi/ml (10 CFR 20 limit). Therefore, all batches were released to the sanitary sewer system.

' Increases in the total volume discharged from 01 Jan 95 to 31 Mar 95 were due to '

hydrostatic testing and draining of the N-16 Tark and primary coolant piping.

2 Based on gross beta activity only. Tritium did not require further dilution.

]

' Corrects typographical error in quarterly and total tritium releases given in the original report. Correction reduces quarterly amount from 16 to 11 Ci and also the corresponding total.  !
