Revision 26 USAR D.1MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 1 of 4APPENDIX DPRE-OPERATIONAL AND STARTUP TESTS I/kabD.1Test Program Summary Description The Monticello Nuclear Generating Plant (MNGP) is owned by Northern States PowerCompany, a Minnesota corporation (NSPM). NSP is a wholly owned utility operating subsidiary of Xcel Energy Corporation (Xcel Energy). Operating authority was transferred to Northern States Power Company, a Minnesota corporation (NSPM) and

approved by the Nuclear Regulatory Commission (NRC) in License Amendment 156.The prime contractor, General Electric was responsible for the design, engineering,furnishing, installation, testing, and placing into operation the machinery, apparatus, and equipment necessary for the complete nuclear powered steam turbo-generator

plant. General Electric also had the contract responsibility which included the design, engineering, and construction of the necessary buildings and structures.

The General Electric Company directed the pre-operational test program performedby General Electric, Northern States Power, and subcontractor (Bechtel) personnel.The startup test program was a joint effort by General Electric and Northern StatesPower. The responsibility for licensed operation during the program was assumed by Northern States Power under the technical direction of the General Electric Company.

The following paragraphs describe the testing program activities and represents a general scope of the testing of the Monticello Plant.D.1.1Construction Testing Construction testing covered a wide range of checks to determine that all components were properly installed and adjusted according to the applicable

manufacturers instructions, manufacturers drawings, AE drawings, control drawings (P and IDs and electrical installation drawings) and that the appropriate system cleanliness had been established. These tests were performed by Bechtel

personnel, subcontractors, or vendors under Bechtel direction. General Electric, as well as Northern States Power, had the opportunity to be present at all tests.

Construction tests results were made available to NSP and GE, and were prerequisite to further testing.01197746 Revision 26 USAR D.1MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 2 of 4 I/kabD.1.2General Conduct of the Pre-Operational and Startup Testing Pre-operational tests were intended to prove by as built test conditions that system design criteria were satisfied. The test procedures were prepared by GeneralElectric or Bechtel Corporation depending upon system design responsibility. These procedures were specific regarding intent, method, and operating requirements.

Summary descriptions of planned tests were supplied in Section 4 and Section 5 of

this appendix.

The contents of the procedures for this program generally included the following:1.The purpose and scope of the test.2.Prerequisites.3.The detailed procedures followed and a brief summary of the test method.

4.Clearly defined limitations for areas pertaining to reactivity and/or safety of operation.5.Cautions observed stating any difficulties peculiar to the tests which were expected.6.Remedial action to be taken if deviations from expected conditions occur.

7.Expected results and appropriate test limits.

8.Acceptance criteria (normally contained throughout the body of the procedure).9.Identify special instrumentation required.

10.Any testing requiring the simulation of a plant parameter had the method to be used detailed in the procedure.

All General Electric and Bechtel approved procedures were submitted to the NSPOperations Committee for review. No pre-operational tests were run without

approved procedures.

Approved procedures were released to the personnel conducting the test. Ifchanges to the procedures were necessary, which were beyond the scope of the test personnel, the test procedure was considered as unapproved and further review was necessary. Changes to the original procedure then required formal

approval.Tests which could not be successfully completed because of improper equipment or instrumentation, or malfunction of equipment or instrumentation were suspended until satisfactory resolution of the shortcoming was completed. If these items cannot be resolved, additional Operations Committee review was necessary.

Revision 26 USAR D.1MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 3 of 4 I/kabAdditional testing, if required, was recommended by Bechtel, General Electric or Northern States Power and was performed when formal approval was obtained.D.1.2.1The Pre-Operational Testing Pre-operational test procedures were submitted to NSP for review by the

Operations Committee. All questions relating to the procedures or the condition of

the plant systems were resolved prior to performance of the test. The

pre-operational test program was periodically reviewed with the Safety Audit

Committee. If any member of the Safety Audit Committee or Operations Committee believed that any test procedure needed formal review by the Safety Audit Committee, the review was conducted and the committee made appropriate

recommendations.

Pre-operational testing was performed by NSP operations personnel under the direction of GE or Bechtel personnel. Procedure change policies were specified by

the Operations Committee.

Formal review by the Operations Committee of the test results and reports wasrequired before each test was considered complete. If sufficient cause was

shown, any previously accepted plant system could have been considered as

unacceptable and require further pre-operational type testing. All plant systems

had to be operationally acceptable when the plant is transferred to NSP control after the power capability performance test.

Certain pre-operational tests were completed after the initiation of the startuptesting; however, the complete pre-operational test program was reviewed by NSP Operations Committee and Safety Audit Committee as to completeness and status prior to the initiation of any startup testing.D.1.2.2Startup TestingThe Monticello startup test program is defined and summarized in the Startup Test

Specification document (22A2190) prepared and released by General Electric.

This document was reviewed by the Operations Committee and the NSP Safety Audit Committee to determine if the scope of the startup testing met the requirements to safely startup the plant, gradually increased to full power operation. Additional testing could be recommended by NSP.The detailed test procedures were prepared in a General Electric Topical Report,22A2192, "Monticello Nuclear Plant Startup Test Procedures." Copies of this

document was available at the Monticello Site approximately three months before

fuel loading.The Startup Test Procedures were reviewed by the Operations Committee and Safety Audit Committee prior to initiation of the tests.

Revision 26 USAR D.1MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 4 of 4 I/kabThe startup tests were performed by NSP personnel under the technical direction of GE startup personnel. Significant deviations from expected test results requireda suspension of testing until the deviation was understood. Testing was not resumed until the Operations Committee had reviewed these deviations.

The results of the startup testing program were continually evaluated to determine if additional testing was required to prove the safety of the reactor and plant

operations. The results of all testing was formally reviewed by the Operations Committee and Safety Audit Committee before the tests were considered complete. The startup tests were conducted at several power levels during the escalation of full power. Power level increases for testing up to 1469 MWt occurred prior to the Safety Audit Committee review of previous testing. However, Operations Committee review of previous test results was required before escalation to the higher power level. Operations at power levels between 1469 MWt and 1670 were not performed until the Safety Audit Committee and the

Operations Committee had reviewed the results of all testing up to and including

the 1469 MWt power level.

Revision 22 USAR D.2MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 1 of 1APPENDIX DPRE-OPERATIONAL AND STARTUP TESTS I/mabD.2Test Program Considerations The following key points were considered in developing the sequence of tests.1.Systems were sequenced for early testing and placed in routine operation to provide necessary auxiliary services for other systems. Examples are plant electrical systems, instrument air and make up water supply systems.2.Pre-operational testing was coordinated with construction to permit fuel loading as early as possible, without compromising nuclear safety or

impeding construction work.3.Stringent controls of plant operation and maintenance work were requiredfollowing fuel loading. To minimize possible contamination problems, pre-operational testing was performed before fuel loading on all systems

which could consequently be exposed to radioactive contamination.4.Pre-operational tests provided an important phase of the reactor plantoperators training program and were scheduled on key systems to permit

maximum participation by all operators prior to NRC licensing examinations.5.Temporary construction power could be required for initial tests at thebeginning of the pre-operational test program. However, the use of

temporary power and improvised set-ups was minimized.6.Electrical jumpers were used to facilitate pre-operational testing in some instances, but their use was minimized and controlled by proper identification of such jumpers by log book records. All jumpers were removed before fuel loading.7.Immediately prior to bringing fuel into the reactor building, the plant access control procedures for the reactor building before were enforced by the Plant

Superintendent. No construction work was performed in the reactor building

without the permission of the GE Operations Manager and the knowledgeand concurrence of the Radiation Protection Engineer. These controlscomplied with the NRC regulations pertaining to radiation safety. In addition, strict control was enforced on access to the control room, cable spreading

room, and radioactive waste building. Other areas to be controlled were

determined by the Operations Committee.FOR ADMINISTRATIVE USE ONLYResp Supv:CNSTP Assoc Ref:

Revision 22 USAR D.5MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 1 of 5APPENDIX DPRE-OPERATIONAL AND STARTUP TESTS I/mabD.5Startup And Power Test ProgramD.5.1General Requirements The startup and power test program was performed to assure that the plant iscapable of operating safely and satisfactorily. Systems and components, which

could not be fully checked out in preoperational test phase were tested at power

during this phase of the unit startup to confirm reactor parameters and

characteristics determined by an extensive program of analysis and tests executed prior to initial fuel loading. The nuclear characteristics of fuel, control rod and control curtains were calculated with methods which were continuously compared with results of experiments in the Vallecitos Atomic Laboratorys

critical facilities, including measurements of similar or identical components. In

addition, startup tests and operating data from other boiling water reactors in commercial operation and other measurements throughout the nuclear industry were used to confirm the applicability of the analytical methods.

Several restrictions were necessary during the initial startup program. All operations and tests complied with the safety and warranty limitations specified

by the General Electric Co. as well as safety limitations and limiting conditions

specified by licensing authorities. Additional restrictions were minimized because the prime objective of the startup program was to demonstrate the plantcapability and safety up to full power. A two hour net heat rate demonstration

was performed at an electrical output corresponding to 1469 MWt. At one

hundred hour test was run at 1469 MWt.D.5.2General Procedures The startup procedures were, with individual detailed subsections.D.5.3Fuel Loading and Tests at Atmospheric PressureThe initial fuel loading and critical testing were performed at near-zero power, and at atmospheric pressure, with the reactor pressure vessel open. The following tests were performed during this phase of the startup program:

a.Chemical and Radiochemical tests were conducted to establish water

conditions prior to initial operation and to maintain these throughout the

test program. Chemical and radiochemical checks were made at primary coolant, off-gas exhaust, waste and auxiliary system sample locations.

Base or background radioactivity levels were determined at this time for use in fuel assembly failure detection and long range activity buildup

studies.FOR ADMINISTRATIVE USE ONLYResp Supv:CNSTP Assoc Ref:

9703 Revision 22 USAR D.5MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 2 of 5 I/mab b.Control Rod Drive System tests were performed on all drives prior to fuel loading to assure proper operability and to measure and adjust operating speeds. Drive line friction and scram times were determined for all drives at zero reactor pressure. Functional testing of each drive was

performed with dummy fuel just prior to and then following the fuel loading

in each cell.

c.Radiation Measurements were made prior to nuclear operation to

establish base levels in the plant and the nearby environs.

d.Fuel Loading was, according to detailed, step-by-step written procedures. The core assembled, with control curtains in place, to the

full-sized core.

e.Shutdown Margin It was demonstrated periodically during fuel loading that the reactor was subcritical by more than a specified amount with the strongest single control rod withdrawn. The shutdown margin requirement was a limitation on the amount of radioactivity which can be

loaded into the core. The magnitude of the margin was chosen with

consideration for credible reactivity changes after the test, and for the

accuracy of measurement. The test had three parts: (a) The analytical determination of the strongest control rod, (b) the calibration of anadjacent control rod, experimentally or analytically, and (c) the

demonstration of subcritcality with strongest rod fully withdrawn and the

second at the position equal to the margin. This demonstration was made

for the fully loaded core, and with selected smaller core loadings.f.The specified Control Rod Sequences were evaluated to verify that thestated criteria of safety, simplicity, and operating requirements were met during routine cold startups. The reactor made critical by withdrawing control rods in a specified sequence and reactivity addition rates were

measured near critical. The preselected sequence could be modified if

necessary to meet criteria. A small number of non-standard arrays were utilized to check out the operation of the rod worth minimizer.

g.Source Range Monitor (SRM) Performance The performance of the source range monitors were evaluated based on data taken with the installed source range monitoring instrumentation and installed

operational sources. The SRM System was calibrated to reactor power

and its performance was compared to stated criteria on noise, signal-to-noise ratio and response to change in core reactivity.

h.Intermediate Range Monitor (IRM) Calibration Calibration of the intermediate range monitors was performed to provide level calibration for the intermediate range monitors adequate for this phase of the test program.i.Process Computer As plant process variable signals become availableto the computer, verifications were made of these signals and of the

computerized systems performance calculations.

Revision 22 USAR D.5MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 3 of 5 I/mabD.5.4Heatup From Ambient to Rated Temperature and Pressure Following satisfactory completion of the core loading and low power test program, the core components were visually verified for proper installation, and the additional in-vessel hardware was installed. This included special monitoring

instrumentation, and steam separator and dryer assemblies.

The reactor head was installed, followed by a hydrostatic test to assure satisfactory sealing of the vessel head. The drywell head was installed and shield plugs placed over it. A sequence of tests was performed to confirm a

number of the nuclear steam supply system characteristics as the temperature and pressure were increased. Sufficient tests were performed at each

incremental step increase in power or change in pressure, and the tests and operating procedures were evaluated, to assure that the succeeding change inoperating conditions could be made safely. The following tests were conducted

during this phase of the startup.

a.IRM Calibration was improved by using data obtained from heatup rates observed during nuclear testing.

b.SRM Performance was determined in the power overlap region with the IRM System. The SRM System was recalibrated by comparison to the

IRM System readings in the region.

c.Reactor Vessel Temperatures were monitored during heatup cooldownto determine that temperature differences were not excessive.

d.System Expansion checks were made during heatup to verify to verify

freedom of major equipment and piping to move.

e.Control Rod Drive systems test were made by measuring scram times on a selected number of drives at two intermediate pressures, scram times and drive line friction tests on a representative set of drives at rated

reactor pressure and on a selected number of drives without

accumulators at rated reactor pressures.

f.Control Rod Sequence to be used during heatup was checked periodically for satisfactory performance.

g.Radiation Measurements were made periodically during nuclear heating

The turbine was placed in service and tested during this phase. The test programincluded the following, but not necessarily at each increment of power. All were

performed during the 1670 MWt tests.

a.Chemical and Radiochemical tests were continued.

b.Radiation Measurements of limited extent were made at 25% of rated power and complete surveys were made at 50 and 100% power.

j.Generator Trip tests were performed to determine speed and reactor response.k.Pressure Regulator tests were made to determine the response of the reactor and the turbine governor system. Regulator settings were optimized using data from this test.

l.Bypass Valves measurements were performed by opening a turbine bypass valve and recording the resulting reactor transients. Final adjustments to the bypass valves were made.

m.Feedwater Pumps were used to change reactor subcooling and the resulting transients were measured to determine system response.

Revision 22 USAR D.5MONTICELLO UPDATED SAFETY ANALYSIS REPORT Page 5 of 5 I/mab n.Flux Response to rods was determined in both equilibrium and transient conditions. Steady-state noise was measured as was flux response to control rod motion. Power-void loop stability was verified from this data.

o.LPRM Calibrations including use of the TIP system, were made at 15,25, 50, and 100% of rated power. Each local power range monitor was

calibrated to read in terms of local fuel rod surface heat flux.

p.APRM Calibrations were performed after making significant power level changes. Reactor heat balances formed the basis of these calibrations ofthe average power range monitor.

q.Core Performance Evaluations were made periodically to assure that the core operated within allowable limits on maximum local surface heat

flux and Minimum Critical Heat Flux Ratio. This test included reactor heat balance determinations.

r.Calibration of Rods were performed to obtain reference relationships between control rod motion and reactor power and steam flow in the specified control rod sequence.

s.Axial Power Distribution measurements were made with the traversingin-core probe system after significant changes in power, control rod, pattern, or flow rate. The TIP system supplied data for core performance

evaluations and LPRM calibrations.
