gf 3-1.0' INTRODUCTION When the low power license for Seabrook is issued, it is expected to contain an accumulated core exposure limitation of 45 effective full power minutes (EFPM). To verify compliance with any EFPM limitations and to simplify the core exposure tracking, an MPCS computer program will be used. JThis functional description specifies the requirements

~

and basis for the calculations that will be used by the program to track accumulated core exposure.

'2. 0 DEFINITION OF TERMS i

EFPM, Effective Full Power Minute

~

u LPPT, Low Power Physics Testing MCB, Main Control Board MPCS, Main Plant Computer System RE, Reactor Engineering 3.0 ASSUMPTIONS s

?

3.1' The power level existing at the time of program execution has existed since the last program execution.

3.2 The response of intermediate range instrumentation versus power level is linear.

~ 4. 0 DESCRIPTION A program for tracking core burnup currently exists on the MPCS; however, it lacks the capability to accurately track core exposure at low power levels. A separate program is required to track core exposure (in EFPM)

Wring low power physics testing. The new program will operate as follows:

4.1' The program will be activated by the periodic scheduler on a 5 minute basis. Since the program is temporary in nature, it will be a stand alone program and will not be incorporated in the existing RE 5 minute task (RE5 MIN).

4.2 Due to the temporary need for the program, no OA1 disc' storage will be used. All tracking will be done with 6 calculated points which are described below:

- Calculated Point 1: This point is the cumulative amp-minutes calculated using intermediate range channel 35 indication. This C point will be updated every program execution.

- Calculated Point 2: This point is the cumulative amp-minutes calculated using intermediate range channel 36 indication. This C point will De updated every program execution.

- Calculated Point 3: This point is the channel conversion con-l stant used to convert intermediate range channel 35 amp-minutes into an EFPM value. This C point will be updated by RE, 's required, using the Analog Management Function at the MCB. This i

. point will not be RELIAB checked since use of a substitute value causes an unreliable flag to be set.

- Calculated Point 4: This point is the channel conversion con-stant used to convert intermediate range channel 36 amp-minutes into an EFPM value. This C point will be updated by RE, as required, using the Analog Management Function at the MCB. This point will not be RELIAB checked since use of a substitute value causes an unreliable flag to be set.

- Calculated Point 5: This point is the current core exposure as of the last program execution. This C point will be updated every program execution.

~

~

- Calculated Point 6: This point is the scan number corresponding to the previous program execution. This C point will be updated

.every program execution.

4.3 Every time the' program is executed, it will perform the following items:

4.3.1 Obtain the analog values for intermediate range chandels 35 and 36, and convert to units of amps.

If one value is unreliable, the alternate value will be substituted for the unreliable value.

If both values are unreliable, a value of zero amps will be assigned to both channels.

4.3.2 The difference in scan number since last program execution

\\

will be calculated and converted to minutes.

I 4.3.3 The Step 4.3.1 values will be multiplied by the Step 4.3.2 delta time to obtain the change in amp-minutes for each intermediate range channel.

4.3.4 The change in amp-minutes from Step 4.3.3 will be added to L

the applicable calculated points to obtain new values of cumulative amp-minutes for each intermediate range channel.

Calculated points 1 and 2 will be updated with the new values.

l 4.3.5 The cumulative a 9-minutes from Step 4.3.4 will be multiplied by the applicable channel conversion constant (calculated points 3 and 4 input into the program and not RELIAB checked) to obtain an EFPM value for each intennediate range channel.

4.3.6 The current core burnup in EFPM will be obtained by averaging the two EFPH values of Step 4.3.5.

The result will be used to update calculated point 5.

4.3.7 Calculated point 6 will be udpated with the scan number of the current program execution.

- 5.0 DETAILS OF CALCULATIONS 5.1 Conversion of MPCS intermediate range analog values to amps.

The analog values for intermediate range channels 35 and 36 are in l

units of MCAMPS. To obtain the required units of amps, the MCAMPS must be multiplied by 10-6, l

5.2 Calculating the time since last program execution and converting to minutes.

Delta Current Scan number

) - ( of previous ) } x [ (5 seconds) x (60 seconds) )

1 minute Time

= [ ( scan (Minutes) number program execution scan Note that if the delta scan time is less than zero (indicating a new day has started), a value of 17,280 will be added to the current scan time in order to obtain the delta scan time.

5.3 Converting amp-minutes to EFPM using channel conversion _ constants.

The value of cumulative amp-minutes for intermediate range channel 35 and 36 is converted to EFPM using channel conversion constants. The initial value of the channel conversion constant is determined as ex-plained below; however, the values should be updated when a more accurate value has been obtained from LPPT data.

Revision 2 of the Precautions, Limitations and Setpoints for Nuclear Steam Supply Systems states that the initial setting for intermediate range channels is such that the full power current for 100% is 10-4 amps. Therefore the initial value for the channel conversion constants

\\

is:

100%

[

10-4 amps 3 g (100%) (1 min) ] = 10 EFPM/ amp-minute During LPPT, overlap data consisting of intermediate range currents and core delta temperatures (in units of % power) will become available.

This data should be evaluated for possible channel conversion constant update as described below:

5.3.1 Verify the data represents stable conditions (constant power level and constant RCS temperatures).

j June 21,1989 FINAL LOW-POWER TESTS APPROACHING FOR SEABR09K STATION'S REACTOR Seabrook Station engineers yesterday completed the flux mapping of the plant's reactor, as preparations begin today for the final series of low-power tests.

During flux mapping, movable instruments travel through the reactor, cvaluating fuel assembly performance and measuring the fission reaction.

Start-up Manager Greg Kann said this morning that the reactor is currently at 1/100th of one percent power.

"All of the reactor's fuel assemblies are working well, and the reactor's performance is as expected," Kann said.

"As soon as authorized, Seabrook Station's reactor is ready to operate at full-power."

Today engineers will continue to gather information on control rod performance and make preparations for the natural circulation test, which will occur at three percent power. During this test, the four reactor coolant system pumps are switched off, and engineers will observe the reactor's performance, and the temperature and pressure of the reactor c:olant system.

Kann said that based on the current schedule, he believes the low-power physics testing of the reactor will be completed by the end of this week.

During testing today and over the next several days, there will be steam reitases which may be visible to area residents.

SEABROOK POLICE SEEK BILLING FOR DEMONSTRATORS Seabrook Police Chief Paul Cronin has asked town officials to send a bill for $12,000 to the Clamshell Alliance to pay for the costs of the June 3 and June a demonstration at Seabrook Station.

News reports have said that Cronin has estimated the cost to the town at $12,000, for payment of additional Seabrook police, the use of police officers from Portsmouth, Hampton and Exeter, the renting of school buses to transport arrested demonstrators and other expenses.

Seabrook selectmen in May billed the Clamshell Alliance $3,315 for the cost of a demonstration in October 1988.

Clamshell Alliance representatives have said they refuse to pay any demonstration bills.

-yesterday's shutdown o. low-power testing at Seabrook Station following

f. the reactor.

New Hampshire-Yankee-President Edward A. Brown said the NRC expressed concerns that control room operators did 'not strictly follow 'a procedure in determining when to shut down the reactor.

"The NRC has indicated to us that they want a thorough review of the reactor shutdown.: and that they would not allow a re-start of the reactor until this. review is complete," Brown said.

cnd thoroughly to the NRC's request, and to answer their. questions -as"We intend to res soon as we can so we can complete these important series of tests."

Brown said. *At no time was there a risk to plant systems or to the general public.

Control room operators at all times maintained safe

-operation of the reactor."~

During testing yesterday, steam was being sent into the condenser from the four steam generators as part of the low-power test program, since the turbine is not being used to produce electricity. Instruments then showed changes in the pressure and temperature of plant systems since too much ste:m was being sent to the condenser through one valve.

Control room operators closed the valve and continued to monitor the system.

After a few minutes, operators were not satisified with the system operation, and decided to manually shut down the reactor at 12:36 p.m.

yesterday.

"We did not strictly adhere to our test procedures during these changes

.in system conditions," Brown said.

"The NRC said we waited several minutes too long before actually performing the shutdown.*'

The. NRC informed New Hampshire Yankee today that it was sending a letter outlining their concerns and their requirements for additional infonnation on yesterday's reactor shutdown. The NRC also said it would l

be scheduling a public meeting to discuss the matter.

1Seabrook Station's plant systems are currently at nonnal operating

pressure and temperature while the reactor is shutdown.

"We take the NRC's concerns very seriously," Brown said.

"We intend to respond to their concerns quickly, and to take all necessary steps to ensure we're in compliance with the NRC's regulations."

K. Abraham S. Horwitz NRC AUGMENTED INSPECTION TEAM SENT TO SEABROOK STATION TO EXAMINE PROBLEM DURING LOW POWER TESTING The Nuclesr Regulatory Commission staff is sending a team of five technical specialists to.Public Service of New Hampshire's Seabrook nuclear power plant. in Seabrook, NH, to determine the circumstances under which the plant was manually shut down on June 22, 1989.

At the time Seabrook personnel were conducting low power testing.

Called an " Augmented Inspection Team," such a group has been used by the NRC staff in the past to examine the causes and consequences of certain events that, by themselves, posed no particular threat to public health and safety, but that nonetheless warrant a thorough review of both hardware and operational issues.

The inspection will commence Wednesday morning, June 28, and is expected to take several days.

The team's findings will be compiled in a special inspection report, which will be made public.

.(603) 474-9521 06/26/89 NEW HAMPSHIRE YANKEE ANNOUNCES COOL DOWN OF SEABROOK STATIO_N Seabrook, N.H. -- New Hampshire Yankee President Edward A. Brown announced today that Seabrook Station operators will begin cooling down the plant within the next 24 to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.

"During the nine days of low-power tests we successfully completed all our physics testing and verified the reactor's design and performance,"

Brown said.

"The only test left is the natural circulation test, a test that can be completed anytime before conmercial operation."

Brown said, "We had hoped to do the circulation test now, but because of the expense and work involved in keeping plant systems at normal operating pressure and temperature, the prudent course is to return plant systems to pre-test conditions. We will do the natural circulation test as part of the normal ascension into full-power operation.

"We now want to concentrate on two issues before us," Brown added.

" Thoroughly fulfilling the Nuclear Regulatory Comission's request for a review of the June 22 shutdown of our reactor, and preparing Seabrook Station for full-power operation later this year."

Brown said New Hampshire Yankee expects to submit its report to the NRC in early July on the June 22 shutdown of the reactor.

"We did not strictly adhere to a test procedure during the June 22' natural circulation test," Brown said.

"We are conducting a thorough review of our response and our procedures, and we will take the appropriate steps to ensure that a circumstance like this does not occur again.

Let me stress that operators were in control of the plant at all times, and there was no possible hazard to plant systems or to the general public during any phase of our low-power test program."

Late this afternoon, New Hampshire Yankee was informed that an inspection team from the NRC would be arriving at Seabrook Station on Wednesday to conduct a review of the June 22 shutdown.

"We intend to fully cooperate with the NRC's inspection team and assist them in their review," Brown said.

"We look forward to resolving this matter, making appropriate modifications, and moving forward to the comercial operation of Seabrook Station."
