SUBJECT:

GRAND GULF NUCLEAR STATION - NOTIFICATION OF NRC TRIENNIAL

HEAT SINK PERFORMANCE INSPECTION (05000416/2019002) AND

REQUEST FOR INFORMATION

Dear Mr. Larson:

On June 17, 2019, the Nuclear Regulatory Commission (NRC) will begin the onsite portion of

the triennial heat sink performance inspection at your Grand Gulf Nuclear Station. This

inspection will be performed in accordance with NRC baseline inspection procedure

(IP) 71111.07 by one inspector from the NRCs Region IV office for one week.

In order to minimize the impact that the inspection has on the site and to ensure a productive

inspection, we have enclosed a request for documents needed for the inspection. The

documents have been divided into three groups.

The first group lists information necessary for our initial inspection scoping activities.

This information should be available to the lead inspector no later than May 6, 2019.

By May 9, 2019, the inspector will communicate the initial selected set of approximately

2-3 risk-significant heat exchangers.

The second group of documents requested includes those items needed to support our

in-office preparation activities. This set of documents, including the calculations

associated with the selected heat exchangers, should be available no later than June 3,

2019. This information should be separated for each selected component, especially if

provided electronically (e.g., folder with component name that includes calculations,

condition reports, maintenance history, etc.). During the in-office preparation activities,

the inspector may identify additional information needed to support the inspection.

The last group includes the additional information above as well as plant specific

reference material. This information should be available onsite to the inspector on

June 17, 2019. It is also requested that corrective action documents and/or questions

developed during the inspection be provided to the inspector as the documents are

generated.

It is important that these documents be as complete as possible, in order to minimize the

number of documents requested during the preparation week or during the onsite inspection.

E. Larson

All requested documents are to be for the time period from the onsite inspection period back to

the last triennial heat sink performance inspection. If nothing addressing a request was done in

that time period, then the request applies to the last applicable document in the previous time

period.

We have discussed the schedule for this inspection activity with your staff and understand that

our regulatory contact for this inspection will be Mr. R. Meister of your licensing organization. If

there are any questions about this inspection or the material requested, please contact the lead

inspector, Wayne Sifre, by telephone at 817-200-1193 or by e-mail at Wayne.Sifre@nrc.gov.

This letter does not contain new or amended information collection requirements subject

to the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). Existing information

collection requirements were approved by the Office of Management and Budget, control

number 3150-0011. The NRC may not conduct or sponsor, and a person is not required to

respond to, a request for information or an information collection requirement unless the

requesting document displays a currently valid Office of Management and Budget control

number.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter

and its enclosure will be available electronically for public inspection in the NRC Public

Document Room or from the Publicly Available Records (PARS) component of NRC's

document system (ADAMS). ADAMS is accessible from the NRC Web site at

http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

2. A schedule of all inspections, cleanings, maintenance, or testing of any plant heat

exchanger to be done during the onsite portion of the inspection

3. Copies of procedures developed to implement the recommendations of GL 89-13,

(e.g., the GL 89-13 Heat Exchanger Program description)

4. Pages from the UFSAR for the GL 89-13 Heat Exchanger Program

5. Maximum GL 89-13 heat exchanger inlet temperatures that still allow full licensed power

operation of the nuclear reactor. Please provide the documents that state these limits

(e.g., UFSAR or Technical Requirements Manual (TRM)) and the operating procedures

that ensure these limits are not exceeded.

III.

Information Requested by June 17, 2019:

1. For the specific heat exchangers selected:

a. Provide the Design Basis Documents and Updated Final Safety Analysis Report

pages for the selected heat exchangers;

b. Copy of the design specification and heat exchanger data sheets for each heat

exchanger;

c. Copy of the vendor manuals including component drawings for each heat exchanger;

d. Copy of the calculation which establishes the limiting (maximum) design basis heat

load which is required to be removed by each of these heat exchangers;

e. Copy of the calculation which correlates surveillance testing results from these heat

exchangers with design basis heat removal capability (e.g., basis for surveillance test

acceptance criteria);

f.

Copy of the calculations or documents which evaluate the potential for water

hammer or excessive tube vibration in the heat exchanger or associated piping;

g. List of engineering-related Operator Workarounds/Temporary Modifications for these

heat exchangers since the last triennial heat sink performance inspection;

h. Copy of the evaluations of data for the two most recent completed tests confirming

the thermal performance of each heat exchanger;

i.

Documentation and procedures that identify the types, accuracy, and location of any

3

special instrumentation used for the two most recently completed thermal

performance tests for the heat exchangers (e.g., high accuracy ultrasonic flow

instruments or temperature instruments). Include calibration records for the

instruments used during these tests;

j.

Copies of those documents that describe the methods taken to control water

chemistry in the heat exchangers;

k. Copies of the documents that verify the structural integrity of the heat exchanger,

e.g., eddy current summary sheets, ultrasonic testing results, and visual inspection

results;

l.

The cleaning and inspection maintenance schedule for each heat exchanger for the

next 5 years;

m. Copy of the document describing the inspection results for the last two cleaning and

inspection activities completed on each heat exchanger;

n. Copy of the document which identifies the current number of tubes in service for

each heat exchanger and the supporting calculation which establishes the maximum

number of tubes which can be plugged in each heat exchanger;

o. Copy of the document establishing the repair criteria (plugging limit) for degraded

tubes which are identified in each heat exchanger; and

p. Information regarding any alarms which monitor on-line performance.

2. For the ultimate heat sink (UHS):

a. Maintenance or inspection of inaccessible below-water portions of the UHS system

including results of underwater diving inspections and assessments of sediment

intrusion and/or removal of sediment; and

b. Documentation of inspections to verify no structural damage to intake structures that

would indicate loss of structural integrity and/or capacity.

3. For the safety-related residual heat removal (RHR) service water and diesel generator

cooling water systems (DGCWS):

a. Copies of the pipe testing and/or inspection program procedures and the latest

completed surveillances and tests verifying structural integrity of the piping;

b. History during the last 3 years of any through wall pipe leak on the system and the

disposition documentation; and

c. Copies of the procedures to monitor, assess, and disposition active through wall pipe

leaks, including structural evaluations and/or planned corrective actions.
