REQUEST FOR A00!TIONAL INFORf!ATION REPORT NUMBER: EI/NNI-77-7 T
R'AR-1 M Radwaste Volume Reduction System
- June 24,19//)
REPORT TITLE:
ORIGINATING CAGAH12AT10N: Energy Incorporated / Newport News Industrial Corporation o
1.
In your discussion of the sizing of the RWR~1TM ystem, you conclude that the system has the capacity to handle 980 m / year. However, present staff estimates indicate that a maximum of 1350 m3/ year for a 3800 MWt boiling water reactor with deep-bed condensate deminerali:ers can be expected. YourreportshouldinjicatethattwoRWR-lMsystems T
would be required to process the 1350 m / year of waste.
'2. Since ycu indicate that the radiciodine adsorbent in the offgas system is silver-imoregnated gel AC 61?0 !;i to e depth of six inches, justify your CF of 625.
'i a OF of 100 is used, what impact does this have on your dose analysis?
3.
Justiff that your. system will operate with radioactive material of the. type and activity range encountered in nuclear power plants by providing experimental data which demonstrates your system's perfor-
- 's mance when processing simulated radioactive waste.
4.
Based on the specific design. features of the RNR-1 volume reduction system, and using conservative estimates of solid radwaste generation rates for both PWRs and SWRs, prc.ide an estimate of the man-rem associated with.each of the following functicns; operations, mainte.1-ance, and inservice inspecticn. State the basis, models, and assumo-tions used to arrive at these values.
5.
Indicate on Figure 2-5 (Pg. 44) the expected radiation zone designa-tiens for each of the radwaste areas shown.
