20555 October 19, 1979 IE Circular No. 79-21 PREVENTION OF UNPLANNED RELEASES OF RADIOACTIVITY Numerous incidents of unplanned releases of radioactivity have been reported to the NRC within the past few months.
These incidents of leaks, overflows and spills have resulted in contamination of areas outside of plant buildings, The attached table provides you with summary information on these events, their apparent causes, the radiological consequences and the corrective actions.
We believe that a number of these incidents could have been avoided and preven-tive actions for these types of unplanned releases should be instituted by all reactor licensees.
Based on the reported incidents, the following preventive measures can minimize the occurrence of such events.
1.
Review of procedures for transfer of radioactive liquids.
Errors in written procedures have led to mistakes in valve line-ups and tank overflows. Wrfi. ten procedures, including check lists for valve line-ups, should be developed and followed for operations which could cause spills of radioactivity. Management controls, including audits, should be employed to assure verbatim compliance with such procedures.
2.
Review of "as built" systems having the potential of inadvertent releases because of design or construction errors.
Consider items such as:
a.
Tank ou rflows should be routed to liquid radwaste tanks.
b.
Storm drains should be located away from areas with a high potential for spills.
Consideration should be given to drip pans under equipment, such c.
as pumps and valves, from which leakage is expected.
d.
Cofferdams should be installed under doors to areas with a potential for radioactive spills, e.
Preoperational testing shoul that would permit radioactiv1 unit (s) under construction.
