W have reir6ewed the radvsete and related sections of the GESSAR-251' j;
PSAR and find that the application 1J sufficiently complete to begin it our formal review and, therefore, is acceptable. 'In the offgas
/,.7 system design, the 10-minute delay line previously provided'for the It steam air ejector offgas has been replaced by a "desiceant dryer" unit.
y This new unit has not bo ddequately described. Enclosed is a list i
dj of additional informatica that will be needed to conform to the a
4-Standard Pormat.and Content of Safety Analysis Reports for Nuclear 5.j Power Plants (Bevision 1).

unresolved issues identified in the GESSAR-238 review be addressed j

For the Compact RECHAR System for treating offgases from the main condenser air ejector exhaust, provide the following information:
(i,s (1) The inventories of radioactive' materials in each s.
component,
.4 (2) the heat generation rate due to radioactive decay in J;
each component,
- r..
G-(3) the maximum temperatures that will be reached at the f
centerline of the desiccant dryer and charcoal delay Ts beds during periods of no flow, 4
g 4!
(4) the volumes and activity levels of liquid wastes
$:q produced when desiccant dryers are regenerated,
?c.,
J (5) the frequency of replacement of desiccant and charcoal, Y
and the isotopic composition of the solid wastes g
- produced, J
'i (6) the dynamic adsorption coefficients employed in your
". )
analysis of the delay time for the desiccant. dryer and justification for the selected values, (7) the volumes and radioactivity levels of gases released when the desiccant dryer is regenerated, and the method g[l of disposing of those gases.
n.
k 012.2 (RSP) 4 (None)
The following unresolved issues have been identified in our 9,!
review of the GESSAR-238 application, and need to be addressed in the GESSAR-251 PSAR:
b,
$M (1) The quality group classification of the components of 9
the liquid, gaseous and solid radioar.tive waste treatment systems do not meet the attached ETSB Position No. 1.
w
[$
(2) The seismic design classification cf a portion of the offgas system and the structure in which it is housed do i
not meet the attached EISB Positiori No.1.

(3) Inndequate storage space is provided for filled solid W
waste containero.
