Title:
BI0 ACCUMULATION OF P-32 IN BLUE GILL AND CATFISH Program Office: NRR Contact Name: Tin Mo Date: 5/21/85 Application to Regulatory Process:
The purpose of this research was to determine the bioaccumulation factor for phosphorus-32 in edible fish tissues. The project was initiated in response to a request from the Office of Inspection and Enforcement, RR-IE-77-1, which needed this information in order to decide whether liquid effluents f rcm pcher plants should be analyzed for P-32.
A final report, NUREG/CR-3981, with the same title as RIL #141 has been published.
An earlier RIL !104 transmitted the results of a review of the relevant literature and described a suggested model for assessing phosphorus bioaccumulation and turnover in fish resulting from such discharges (NUREG/CR-1336). Because of the uptake and metabolism of phosphorus in fish, this pathway was considered to be important for estimating potential doses to members of the public for compliance with 10 CFR 50, Appendix I.
NRR requested experimental confirmation of the model proposed in NUREG/CR-1336.
Impact of Results:
The results from the experiments done for this study confirm the model proposed in NUREG/
CR-1336 and show that the value of 100,000 used in Regulatory Guide 1.109 for the phosphorus bioaccumulation factor for freshvater fish may be lowered.
The results from these studier have been very useful to NRR in reducing some of the sur-veillance requirements of nuclear power plants while still protecting the public's health and safety.
Comments /Rema rks The research program is complete. No further work is scheduled nor recommended. The research results do not contain information that should be considered for Board notification.
