SUBJECT:

ERRATA TO PROPOSED SRP SECTION 6.5.5 Due to an error in transmitting the text four late additions and changes to the subject Proposed SRP Section did not appear in the printed and distributed copies. These changes are:

Page 6.5.5-2, second paragraph under heading II, beginning "Where they can be shown ...." A sentence should be added to the end of this paragraph. This addition is "Other assumptions concerning the release of radioactivity are to be taken from Regulatory Guide 1.3, except for Position C.1.f., which this section replaces."

In specific criterion 3 of the next paragraph, the first sentence should '

read: "For plants which have already received a construction permit, the iodine retention calculated using this section must not be used to ' justify removal of the standby gas treatment or other filtered exhaust system from status as engineered safety features and any change in plant design, proposed testing, surveillance or maintenance must be supported by considerations of lowered operator dose and other projected benefits."

. Page 6.5.5-3, first paragraph under heading 1, Pool decontamination factor, ,

l should read as follows:

"The decontamination factor (DF) of the pool is defined as the ratio of the amount of a contaminant entering the pool to the amount leaving. Decontami-nation factors for each fission product form as functions of time can be calculated by the SPARC Code (Ref. 2). An applicant may use the SPARC Code or other methods to calculate the retention of fission products within the pool, provided these methods are adecuately described in the SAR to pennit review.

If the time-integrated DF values claimed by tN applicant for removal of particulates and elemental iodine are 10 or less for a Mark II or a Mark III BWR; and are 5 or less for a Mark I BWR, the applicant's values may be accepted without any need to perform calculations (Refs. 3, 4). A DF value of 1 (no retention) should be used for noble gases and, unless the applicant demonstrates otherwise, for organic iodides as well. The applicant should provide extensive justification for any DF values greater than those given above."

An additional reference should be added: "4 R. S. Denning et al, "Radionuclide Release Calculations for Selected Severe Accident Scenarios."

NUREG/CR-4624, Vol. 1."

Because of deleys prospective commenters might experience due to these changes, the coninent period will be extended to July 7,1987.
