7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION GEORGIA.30WER COMPANY, ET AL DOCKETS NOS. 50-321 and 50-366 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENTS TO FACILITY OPERATING LICENSES AND OPPORTUNITY FOR PRIOR HEARING The United States Nuclear Regulatory Comission (the Comission) is considering issuance of amendments-to Facility Operating Licenses Nos.
DPR-57 and NPF-5 issued to Georgia Fower Company, Oglethorpe Power
~'
Corporation, Municipal Electric Authority of Georgia, City of Dalton, Georgia, (the licensees), for operation of the Edwin I. Hatch Nuclear Plant, Units Nos. I and 2, locat'ed in Appling County, Georgia.
In accordance with the licensees' application for amendment dated February 6,1984, as supplemented April 3,1984, the amendments would modify the Technical Specifications for both Units 1 and 2 as follows:
1.
Change the slope of the flow-biased Average Power Range Monitor / Simulated Thermal Power Monitor (APRM/STPM) scr% ar red block set;'ints from 0.66 to 0.58 and change their intercep \\ f.g och that, at rated core flow, -
the setpoints are unchanged from their current values.
2.
Delete the requirement for setdown of the APRM/STFM flow-biased scram and rod block setpoints when core maximum fraction of limiting power density (MFLPD) exceeds the fraction of core rated thermal power (core 8406010059 840510 PDR ADOCK 05000321 p
( x
._ =
2-7590-01 total peaking factor exceeding design peaking factor).
In order to maintain function and margins, replace the setdown requirement with new16ultipliers to the minimum critical power ratio (MCPR) and average planar lin' ear heat generation rate (APLHGR) operating limits when core e
power or flow conditions are less than t.be licensed conditions.
3.
Replace the Rod Block Monitor (RBM) flow-biased trip equation with power-dependent setpoint definitions, incorporate RBM filter and time delay setpoints, and change the RBM downscale trip setpoint. Add g
appropriate RBM operability and surveillance requirements, including the. definition of Limiting Rod Pattern for Rod Withdrawal Error (RWE).
t 4.
The amendments would make edito- %1 changes to the Technical Specifications for Unit 1 only as follows:
Clarify (1) the definition of the bypass power level below which a.
turbine stop and control valve position scrams are not required; (2) the descriptions of the ' functional dependence of the j
operating limit MCPR and the APLHGR limit; (3) the figure captions assigried to the rated power-rated flow MCPR operating limits; (4) the-nomenclature used,and the maximum allowable setpoint for the APRM high neutron flux scram and the STPM scram; c
~
(5) the numbering of sections under thg Limiting System Safety Settings Neutron Flux Trips; (6) the nomenclature for the APRM Rod Block and RBM upscale trips; and (7) the references.to Limiting Rod Pattern, adding the phrase "for R'WE".
b.
Change the Technical Specification bases to (1) delete references to the'APRM/STPM scram and rod block peaking factor setdown-i requirement;-(2) identify the RBM system logic changes and..

descriptions of the K MCPR multiplier, the power and p
flow-dependent MAPLHGR multipliers, and the governing MCPR operating limit 'and MAPLHGR limit; (4) delete the Core Thermal Power Limit versus Core Flow Rate Map (Figure 1.1-1) and add a reference to document where the correct map is presented; and (5) correct a reference to the 80*F Loss of Feedwater Heating Event.
5.
The amendments would make editorial changes to Technical Specifications for Hatch Unit 2 only as follows:
Clarify (1) the definition of the bypass power level below a.
which turbine stop and control valve position scrams are not required; (2) the descriptions of the functional dependence of
~
the operating limit MCPR and the APLHGR limit; (3) the figure

. captions assigned to the rated power-rated flow MCPR operating limits; and (4) footnote (a) in Table 3.3.5-2 relating to the APRM rod block flow dependence, b.
Change the Technical Specification bases to (1) delete t
references to the APRM/STPM scram and rod block factor setdown requirement; (2) identify the RBM system logic changes and.
operability requirements; (3) replace references to the K f
l analysis bases with descriptions of the MCPR bases and add 7
descriptions of the K MCPR multiplier, the power and p
flow-dependent MAPLHGR multipliers, and the governing MCPR operatinglimitandMAPLHGRlimit;(4)addaclarifyingremark to the introduction of the Power Distribution Limits Bases; (5) add to the. lists of references where appropriate; and (6)< delete a reference to cycle-specific OLMCPR transient results..

7590-01 Prior to issuance of the proposed license amendments, the Comission will have made findings required by the Atomic Energy Act of 1954, as amended (the Act) and the Comission's regulations.
By June 14, 1984, the licensees may file a request for a hearing with respect to issuance of the amendments to the subject facility operating
~
licenses and any person whose interest may be affected by this proceeding and who wishes to participate as a party in the proceeding must file a written petition for leave to' interve'ne. Request for a hearing and petitions for leave to intervene shall be filed in accordance with the Commission's
" Rules of Practice for Domestic Licensing Proceedings" in 10 CFR Part 2.
If a request for a hearing or petition for. leave to intervene is filed by the above date, the Comission or an Atomic Safety and Licensing Board, designated by the Comission or by the Chairman of the Atomic Safety
~
4 and Licensing Board Panel, will rule on the request and/or petition and the Secretary or the designated Atomic Safety and Licensing Board will issue a notice of hearing or an appropriate order.
As required by 10 CFR 92.714, a petition for leave to intervene shall set forth with particularity the interest of the petitioner in the proceeding and how that interest may be affected by the results of the proceeding. The l
l petition should specifically explain the reasons why intervention should be l
l permitted-with particular reference to the following factors:
(1) the nature of the petitioner's right under the Act to be made a party to the proceeding; (2) the nature and extent of the petitioner's property, financial, or.other interest in the proceeding; and (3) the possible effect of any order which may l
a e
. 7590-01
~
be entered in the proceeding on the petitioner's interest. The petition should also identify the specific aspect (s) of the subject matter of the pro-i ceeding as to which petitioner wishes to intervene. Any person who has filed a petition for leave to intervene or who has been admitted as a party may amend the petition without requesting leave of the Board up to fifteen (15) days prior to the first prehearing conference scheduled in the proceeding, but such an amended-petition must satisfy the specificity requirements described above.
Not latar than fifteen (15) days prior to the first prehearing conference scheduled in the proceeding, a petitioner shall file a supplement to the peti-tion to intenene which must include a list of the contentions which are sought to be litigated in the matter, and the bases for.each contention set forth with
. reasonable specificity. Contentinns shall be limited to matters within the
'~
scope of the amendments under consideration. A petitioner who fails to file
- l l'
such a supplement which satisfies these requirements with respect to at. least one contention will not be permitted to participate as a party.
Those permitted to intervene become parties to the proceeding, subject to any limitations in the order granting leave to intervene, and have the oppor-tunity to participate fully in the conduct of the hearing, including 'the' opportunity to present evidence and cross-examine witnesses.
i A request for a hearing or petition for leave to intervene shall be filed with the Secretary of the Conunission, United States Nuclear I
