SUBJECT:
CONCURRENCE ON THE COMMISSION INFORMATION PAPER ON THE VIABILITY OF THE ENTOMBMENT OPTION AS A 2
DECOMMISSIONING ALTERNATIVE FOR TERMINATING POWER REACTOR LICENSES
)
REFERENCE:
Memorandum, subject as above, from Ashok C. Thadani to Samuel J. Collins, et al., dated June 2,1999 I
i The referenced memorandum requested NRR to review and concur on an attached draft information paper to the Commission regarding the viability of entombment as an acceptable decommissioning option. NRR concurs in the proposed information paper with the following comments.
Regarding page 3, first full paragraph, first sentence,"The PNNL evaluation provides convincing ev/dence that..."(italics added). This appears to overstate the strength of the information contained in the PNNL evaluation. NRR suggests a revision to state,"The PNNL evaluation demonstrates that..." or other words to that effect.
I Regarding the PNNL evaluation, page 2, third full paragraph, line 5, NRR suggests a revision to read, "...so that unacceptable health consequences do not result." (revision in italics)
(W, j x
Regarding the PNNL evaluation, page 5, the set of bullets identifying characteristics of y) commercial power reactors (specifically the second bullet concerning plants being " located in an arid region having a low population density"), NRR notes, among all the commercial power reactor sites in the U.S., there appears to be only two sites clearly having this characteristic (Palo Verde and WNP2).
l Regarding the PNNL evaluation, page 9, section titled " Residential / Farm Familv," NRR suggests consideration of three additionalitems for inclusion in this section: (1) some power plants located on rivers are protected from floods by maintenance of dikes and other flood control measures, (2) some plants, such as Oyster Creek, require cathodic protection of the drywell, and (3) Humboldt Bay experienced substantial water intrusion (several thousand gallons per day) for an extended period into the caisson (reactor building) before major corrective modifications were implemented.
