37. SITE BOUNDARY The Site Boundary is that line beyond which the land is neither owned, nor leased, nor otherwise controlled by IELP. UFSAR Figure 1.2-1 identifies the DAEC Site Boundary. For the purpose of implementing radiological effluent controls, the Unrestricted Area is that land (offsite) beyond the Site Boundary
38. ANNUAL Occurring every 12 months.

For the purpose of designating surveillance test frequencies, annual surveillance tests are to be conducted at least once per 12 months.

39. CORI OPERATING LIMITS REPORT The Core Operating Limits Report is the DAEC-specific document that provides ,

cycle-specific operating limits for the current operating reload cycle. These cycle-specific operating limits shall be dstermined for each reload cycle in accordance with TS 6.11.2. Plant operation within these limits is addressed in individual technical specifications.

40. Shutdown Marcin Shutdown margin is the amount of reactivity by which the reactor is suberitical or would be suberitical assuming all control rods are inserted, except for the analytically stroagest worth control rod, which-is fullyswithd with the core in its most reactive state during the OPERATINGhCys4e4 C YC LE. .

8. Core Themsl Power Limit (Reactor Pressure 1735 psig or Core Flow 110%

of Rated)

At pressures below 7ES psig, the core e+aNation : essure droo (0 power, O flow) is greater than a.56 psi. At low power and 111 flows, this pressure differential is maintained in the bypass region of tne core. Sint.e the pressure drop in the bypass region is essentially all elevation head, the core pressure drop at low power and all flows will always be greater than 4.56 psi.

Analyses show that with a flow of 28 x 101bs/hr 3

bundle flow, bundle pressure drop is nearly independent of bundle power and has a value of 3.5 psi. Thus,

__ the bundle flow with a 4.56 psi driving head will be greater than 2B x 103 lbs/hr irrespective of total core flow and independent of bundle power for the range of bundle powers of concern. Full scale ATLAS test data taken at pressures from 14.7 psia to 800 psia indicate that the fuel assembly critical power at this flow is approximately 3.35 MWt. With the design peaking factors this corresponds to a core thermal power of more than 50%. Thus, a core thermal power limit of 25% for reac' tor pressures below 800 psia or core flow less than 10% is conservative. -

C. Power Transient" Plant safety analyses have shown that the scrams caused by exceeding any ..

safety setting will assure that the Safety Limit of Specification 1.1.A or 1.1.8 will not be exceeded. Scram times are checked periodically to a$sure the insertion times are adequate. The themal power transient resulting when a scram is accomp edather than by the expected scram signal (e.g., scram from neutron flux folowing close of the main turbine stop valves) does.not necessarily cause ue damage. However, for this specification a Safety Limit violation will be asstrned when a scram is only accomplished by means of a backup feature of the plant design. The concept of not approaching a Safety Limit provided scram signals are operable is supported by the extensive plant safety analysis.

2. APRM Hich Flux Scram (Refuel or Startuo & Hot Standby Model For operation in these modes the APRM scram setting of 15 tercent -

of rated power and the IRM High Flux Scram provide adequate thermal margin between the setpoint and the Safety Limit, 25 percent of rated. The margin is adequate to accommodate anticipated maneuvers associated with power plant startup. Effects of increasing '

. pressure at zero or low void content are minor, cold water from sources available during startup is not much colder than that already in the system, temperature coefficients are small, and control rod patterns are constrained to be uniform b ting procedures backed up by , cad the Rod ,

e A Scquence Contr:1 System. Worths of individual rods are very low in ,

a uniform rod pattern. Thus, of all possible sources of reactivity input, uniform control rod withdrawal is the most ~ probable cause of significant power rise.

Because the flux distribution associated with uniform rod

- withdrawals does not involve high local peaks, and because several  !

rods must be moved to change power by a significant-pen:entage of .

rated power, the rate of power rise is very slow. Generally, the heat flux is near equilibrium with the fission rate. In an assumed -

uniform rod withdrawal approach to the scram level, the rate of power rise is no more than 5 percent of rated power per m.inute, and the APRM system would be more than adequate to assure a scram I

before the power could exceed the Safety L'imit. The 15 percent Amendment No.119 1,1 13 g43 263 l n/Y: ,

The IRM system consists of 6 chambers, 3 in each of the reacter protection system logic channels. The IRM is a 5-decade instrument which covers the range of power level between that covered by the SRM and the APRM. The 5 decades are covered by the IRM by means of a

.l range switch and the 5 decades are broken down into 10 ranges, each being one-half of a decade in size. The IRM scram trip setting of i

120 divisions is active in each range of the IRM. For example, if the instrtment were on range 5, the scram would be 120 divisions on that range. Thus, as the IRM is ranged up to accommodate the increase in power level, the scram trip setting is also ranged up. The most I significant sources of reactivity change during the power increase - l are due to control rod withdrawal. For insequence control rod withdrawal, the rate of change of power is slow enough due to the --  !

physical limitation of withdrawing control rods that.the heat flux is

~

in equilibrium with the neutron flux, and the IRM scram would result i l

1 in a reactor shutdown well before any Safuty Limit is exceeded.

In order to ensure that the IRM provides adequate protection against-the single rod withdrawal error, a range of rod withdrawal accidents has been analyzed. This alysis included starting the accident at 1

. 7. 3. 2. .', 2. 4 Section 1.3.1.1.24. jFor some limited 2 cw probability accidents with the recirculation loop operating with large speed differences, it is possible for the 4 logic to select the wrong loop for injection. For these limited conditions the core spray itself is adequate to prevent fuel temperatures from exceeding allowable limits. However, to limit the probability even further, a procedural limitation has been placed on the allowable variation in speed between the recirculation pumps.

The licensee's analyses indicate that above 80% power the loop select logic could be '

expected to function at a speed differential up to 14% of their average speed.  !

Below 80% power the loop select logic would be expected to function at a speed '

differential up to 20% cf their average speed. This specification provides margin  ;

because the limits are set at 110** and $15% of the average speed for the above and below 80% power cases, respectively. If the reactor is operating on one recirculation pump, the loop select logic trips that pump before making the loop selection.

DAEC-1 The pressure suppression pool water provides the heat sink for the reactor i

primary system energy release following a postulated rupture of the system. '

The pressure. suppression chamber water volume must absorb the associated decay and structural sensible heat released during primary system blowdown from 1040 psig. Since all of the gases in the drywell are purged into the ]

o pressure suppression chamber air space during a loss-of cglant accident, the_ '

I pressure resulting from isothermal compression plus the vapor pressure of the licuid must not exceed 62 psig, the suppression chamber maximum

  • allowable pressure. The design volume of the suppression chamber (water and 1

Introduction  ;

By letter dated December 22, 1993, Iowa Electric Light and Power '

Company (IELP) submitted a request for revisionlif the Technical  !

Specifications (TS) for the Duane Arnold ~ Energy Center (DAEC).  !

The proposed changes are editorial in nature and will eliminate j discrepancies discovered in the recent comparison.of the IELP j controlled copy with the NRC authority copy of the DAEC TS. '

Assessment The proposed changes to the DAEC TS correct administrative and  :

typographical errors. None of the revisions would result in a l

change to the systems, structures or components in the plant or operation-thereof. .The revised TS will result in continued safe' '

operation of the DAEC and elimination of some administrative and typographical errors in the TS~. .

Based upon the above information, we have concluded that the proposed changes to the DAEC TS are acceptable. d l

l ENVIRONMENTAL CONSIDERATION  !

10 CFR 51.22(c)(9) identifies certain licensing and regulatory actions  !

- which are eligible for categorical exclusion from the requirement to r perform an environmental assessment. A proposed amendment to.an operating f

involve a significant hazards consideration; (2) result in a significantL -!

. change in the types or significant increase in the amounts of any effluents ,

that may be released offsite; and (3) result in an increase in individuali  ;

or cumulative occupational radiation exposure. Iowa Electric Light and Power has reviewed this request and determined that the proposed. amendment

. meets the eligibility criteria for categorical exclusion set forth in 10 i

CFR'51.22(c)(9). Pursuant to 10 CFR 51.22(b),.no environmental impact- l

- statement or environmental assessment needs to De prepared in connection j with the issuance of the amendment. The basis for this determination  ;

follows: 'j Basis i;

'i The change meets the eligibility criteria for categorical exclusion set  ;

forth in 10 CFR 51.22(c)(9) for the following reasons: {

l

1. As demonstrated in Attachment 1 to this letter, the proposed Amendment-  ;

does not involve a significant hazards consideration.  !

i

2. The proposed Amendment makes editorial changes to correct  ;

administrative and typographical errors. No changes in.either design or operation of the DAEC will be made as a result of these changes; 'j thus, there will be no increase-in either the types or amounts of ,

effluents that may be released offsite.  :
