f 5.
Scheduled date(s) for submitting proposed licensing action and supporting information.
6.
Important licensing considerations associated with refueling, e.g.,
new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.
7.
The number of fuel assemblies: (a) in the core and (b) in the spent fuel storage pool.
8.
The present licensed spent fuel pool storage capacity and the size of any increase in Itcensed storage capacity that has been requested or is planned, in number of fuel assemblies.
9.
The projected date of the last refueling that can be discharged to.
the spent fuel pool assuming the present licensed capacity.

-c ODCM REVISION The following pages are an addendum to the previous Monthly Operating Report.
The prior report contained a section describing revisions (Revision 11A) made in the ODCM.
However, the revised pages were not included in that report.
The ensuing pages are the aforementioned.
1397t
- 0934A
i Revisions to the Offsite Dose Calculation Manual (0DCM) are reportable to the NRC in accordance with Station technical specifications. The document i
contains the models for the public dose assessment from gaseous effluents, liquid discharges, and direct radiation.
In 1988, in response to the NRC's request to make the ODCH a more readable document as well as to incorporate certain changes Commonwealth Edison rewrote its ODCH.
This document renumbered to Revision 0, March, 1989, will be submitted under separate cover.
This summary describes the principal non-edited changes.
MM0iLCHANGE The NRC, in NuReg 0472, Rev. 3 Draft 7, has identified the child's thyroid and not in infant's as the most sensitive organ from the inhalation of airborne effluents.
Dresden, LaSalle, and Quad Cities Stations' 10CFR20 instantaneous release rate limits have been revised to restrict the dose rate to the child's thyroid to less or equal to 1500 mrem /yr.
Hydrogen addition to the primary coolant increases the boiling water reactors' turbine N-16 :kyshine by a magnitude of 5.
This phenomenon is now included in the ODCM formulation.
In addition the skyshine calculation is written for LaSalle County Station as well as revised in Dresden and Quad Cities.
MINQlLCHANGES Most of the ODCM documentation has been either clarified, corrected or deleted.
Plume depletion, terrain factors and heat content were not accounted for in the original for D/0, X/0 and plume rise calculations.
They are described in the revised document.
It was implied that the X/0 dose factors were calculated assuming a monoenergetic gamma energy having an average gamma ray energy per disintegration for each radionuclide.
Also, it was assumed that the corrected tissue absorptions were made using a tissue energy absorption coefficient equivalent to this same average gamma ray energy for each radionuclide.
Actually, the dose factors and the tissue energy absorption coefficients I
referenced were calculated using the photon energy spectra for each I
radionuclide.
The tissue energy absorptions coefficients are negligible and have been deleted from the text.
Formulas and parameters for deterniining the maximum permissible concentrations (MPC's) have been eliminated from the section on radioactivity in storage tanks.
The maximum limits, in curies, are found in the site specific sections.
The potential direct radiation dose from stations' interim radwaste storage facilities is discussed.
The radwaste containers will have a contact dose rate of 5 R/hr and the expected radiation levels will be minimal at the site boundary.
1397t 0934A
The distante dependent parameters were adjusted to the values reported in the
'88 census for nearest residents and/or nearest milk animal. This also affected the D/0 tables and BHR turbine N-16 skyshine calculation.
The time of travel from the station liquid discharge to the nearest comhtunity water supply was reevaluated for Braidwood and Quad Cities.
It has been determined that the change will not reduce the accuracy or reliability of dose calculations or set point determinations.
ODCH Revision 0, March 1989 has received approvals by all six on-site review committees and the CECO offsite review per the Technical Specifications.
Changes to the ODCH computer program required by this document are in the process of being implemented now and should be fully available by November 1, 1989.
