SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 90 TO FACILITY OPERATING' LICENSE NO. DPR-66 DUQUESNE LIGHT COMPANY OHIO EDISON COMPANY PENNSYLVANIA POWER COMPANY
~ BEAVER VALLEY POWER STATION, UNIT NO. 1 l
DOCKET N0. 50-334 INTRODUCTION i
By letter dated June 28, 1984, Duquesne Light Company (the licensee) i proposed administrative changes to the Technical Specifications (TS) set forth in Appendix A to the license for the purpose of revising several Tables associated with the instrumentation for radioactive gaseous effluent monitoring and engineered safety features.
DISCUSSIl}N AND EVALUATION The proposed changes and the staff's evaluation of each are as follows:
(1) Table 4.3-13 would be revised to reflect the fact that Radiation Monitors RM-VS-170A and B only measure the nonnal operation activity l
in'the reactor building exhaust and provide an alarm in the control l
room on high noble gas activity. The present technical specification calls for periodically checking the alarm function and also automatic isolatic.i of the exhaust. Since automatic isolation of the reactor.
i building exhaust is not provided (nor is it required), the technical l
specification change would delete checking for isolation but maintains surveillance checking for control room alarm on high effluent activity.
a l.
The technical specification change concerning the inlet activity monitor RM-6W-101 to the gaseous waste storage tanks would be revised to include the control room alarm check on high activity.
i Those changes to Table 4.3-13 are administrative in nature and are acceptable.

(2) The licensee requested to change the entries for the setpoint and
^
allowable value for Functional Unit 4.e, High Negative Steam Pressure L
Rate, in Table 3.3-4 from "100 psi" and "110 psi" respectively to l
"<100 psi with a time constant of 50 + 5 sec." and "<110 psi with a time constant of 50 + 5 sec." respectTvely. These cfianges were intended to add the appropriate time constant consistent with the l
functional requirements of the circuitry.

(3) Thelicenseerequestedtoadd'approphiateentriesinTfbles3.3-3, 3.3-4 and 4.3-2 under Functional Unit 7. " Auxiliary Feddwater" for
" Turbine Driven Pump Di,scharge Pressure Low." This signal provides a L
back-up signal to ensure that the motor-driven auxiliary feedwater pumps start if the turbine-driven pump does not. The staff finds these additional entries acceptable for this diverse function.
i In addition, the licensee requested to add an appropriate entry in Table 3.3-5 for the " Turbine Driven Pump Discharge Pressure Low" i
signal.
The staff finds this change acceptable as discussed above.
The. licensee.also requested to change table notation 1 for Table 3.3-5 j
to agree with the previously revised (Amendment 65) format of Table 3.6-1 to which this no'te refers.
The staff finds this administrative j
change acceptable.
i ENVIRONMENTAL CONSIDERATION i
This amendment. involves a change in the installation or use of facility comp 6nents located within the restricted area.
The staff has determined that the amendment involves no significant increase in the amounts of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupation radiation exposure.
The Conalssion has previously issued a proposed finding that this amendment ir.vol,ves no significant hazards' consideration and there has been no public -
consent on such finding.
Accordingly, this amendment meets the eli criteria for categorical exclusion set-forth in '10 CFR Sec 51.22(c)gibility.
4 (9).
Pursuant to 10 CFR 51.22(b) no envirormental impact statement or environmental' assessment need be prepared in connection-with,the issuance of 4
this amendment.
L CONCLUSION j
We have conc hded, based on the considerations discussed above, that':

there is rea unable assurance that the health and safet activities will b'e' y operation in the. proposed manner, y of the pu not be endangered b and(2)such conducted in compliance with the Connission's regulations and;the issuance of this amendment wiTl not be 1"nimical to the common defense or security or to the health and safety of the public.
