( l.0 INSTRUCTIONS 1.1 General 1.1.1 Requirements 1
The regulatory requirements for a Fuel Storage Pool and Makeup Monitoring Program are contained in Haddam Neck Technical Specification 6.8.1.g.
1.1.2 Objectives l
The objective of this Program is to provide reasonable assurance that the structures, systems and components (SSCs) and water sources used for forced ;
spent fuel pool cooling and for maintaining spent fuel pool water level are 1 capable of fulfilling their intended function.
1.1.3 Program Scope,and Applicability The Program requires that the crimary method for spent fuel pool cooling and the primary method for spent fuel pool water makeup capability be monitored and maintained. Definitions for monitoring and maintaining are fqpd in Attachment 1. " -
[
Although the Service Water System (SWS) provides the existing heat sink for the fuel pool, this system is scheduled to be replaced in the fourth quarter of 1998. Based on this, individual SWS components are not included in Attachment 2. However, the SWS will centinue to be monitored by verifying it provides adequate heat sink to maintain fuel pool temperature within normal limits. SWS monitoring will cease when the Intermediate Cooling and Spray Cooling Systems are performing the heat sink function.
The Program is applicable to those activities that ensure the continued function of the SSCs and water sources used for forced spent fuel pool cooling and for maintaining spent fuel pool water level. Equipment, and components included in this program are itemized in Attachment 2.
1.2 . Program Elements 1.2.1 Spent Fuel Quality Assurance (SFQA) Program Reduces the likelihood of an unplanned loss of forced Spent Fuel Cooling through application of a QA program to applicable Equipment, Components and Systems.

( Fuel Quality Assurance Program" 1.2.2 Spent Fuel Pool Leakage Monitoring Spent Fuel Pool Leakage Monitoring includes:
l l
- _ Observation of system / pool integrity; e Measurement and trending of water additions to the fuel pool; e Collection, measurement, analysis and trending of water collected from the liner leakage collection standpipe;
- Periodic visual leakage checks of system boundary valves; and e Periodic sampling / analysis of monitoring wells located to the west of the fuel building.
. Radiation monitoring of the secondary side of the fuel pool heat exchangers.
Procedures that implement leakage monitoring activities include:
. ENG 1.7-175," Fuel Pool Leakage Monitoring"
. RPM 5.1-3," Collection of Surface and Subsurface Soil, Shoreline Sediment, Asphalt and Liquid Samples for Scoping and ., e ,
( Characterization Surveys" ,
1.2.3 Water Chemistry Control
) Vater chemistry control is achieved by: (1) Using high quality water for system initial filling and normal makeup,(2) Purifying water during opervion using installed or temporary filters and/or demineralizers, and (3)
Periodically sampling and analyzing of systems water and adjusting the use of purification subsystems as necessary to maintain high quality water in the l systems.
. The Spent Fuel Pool Cooling (SFPC), Intermediate Cooling (IC),
Spray Cooling (SC) and Primary Water (PW) Systems are filled with demineralized water.
. The normal makeup to the SFPC, IC, and SC systems is demineralized water.
. The SFPC System has a skimmer pump and filter subsystem that removes surface particulates.
The SFPC system also has a purification subsystem that is designed to
( e Processes fuel pool water through a filter and demineralizer.

( e These subsystems will be operated as necessary to maintain fuel pool water quality within applicable specifications.
- The IC System is closed loop and is nst normally subject to water quality degradation. The System has side-stream filters for removal of fine particulates. These filters are in operation whenever the IC system is in operation. I e Sodium Hypochlorite treatment of the SWS, as necessary, reduces j the probability of fouling in the fuel pool heat exchangers while SWS is used as the heat sink.
When necessary, techniques will be utilized to maintain water quality within applicable specifications whenever forced cooling of the fuel pool is required.
- The SC System has side-stream filters for removal of fine particulates.
These filters are in operation whenever the SC is in operation.
. Sampling and analysis of the fuel pool water is performed at a frequency to ensure anomalous water chemistry conditions are identified before they could cause degradation of the fuel, fusi pool liner, fuel racks or cooling system components.
(
- Re SFPC and SC Systems water chemistry control mechanisms will be adjusted based on the results of sampling / analysis. l Water chemistry sampling, analysis and acceptance criteria are contained in the following procedures:
e CHDP 1.0-4," Chemistry Data Review" 1.2.4 Freeze Protection The Primary cooling system and Primary makeup system are protected from freezing by the following: (1) Most of the system components are located within heated areas / buildings, (2) Components located outside heated areas are either engineered to be passively protected against freezing by draining or are heat traced, or are heated, and (3) Monitoring of system operation,

. Original weather conditions and heat tracing ensures potential freezing conditions are
( identified and rectified before system damage can occur.
I Procedures that provide monitodng of weather conditions, building heating and elecide heat trace operation include:
- PMP 9.9-146 " Freeze Protection Equipment Preventive Maintenance" i e PMP 9.1-52 " Cold Weather Operations" 1.2.5 Decommissioning / Nuclear Island Maintenance Rule Manual Maintenance Rule compliance facilitates the integration of other CY programs and processes which impact the plant maintenance functions during decommissioning.
Maintenance Rule compliance is the primary objective. The program provides reasonable assurance that the structures, systems, and components (SSCs) required to maintain Spent Fuel Storage function and that SSC performance is routinely monitored.
1.2.6 Component Readiness Inspectionffesting Program
( This program establishes the requirements for component readiness testing of pumps, valves, pressure relief devices, supports and pressure leak inspections required to support safe storage of spent fuel at CY.
1.2.7 Normal Operation The following procedures ensure normal operation of the systems is adequately monitored and controlled:

NOTES
- 1. The current heat sink for the fuel pool is the SWS. However, this will be replaced by the Intermediate Cooling and Spray Cooling during the fourth quarter of 1998.
.o
( 2. Operation of the spray cooling pumps and fans is optional, depending ori' atmospheric conditions, and is controlled consistent with Freeze Protection The Primary method for spent fuel pool cooling is forced cooling using one fuel pool cooling pump, and one fuel pool heat exchanger. The heat sink for the fuel pool heat exchanger consists of one of the following:
- 1. One Service Water Pump and a flow path from the pump to a fue. ~, ieat exchanger and to the Service Water Discharge Header.
- 2. One Intermediate Cooling Pump with flow through one Spray Cooler, one spray cooling pump and two spray cooler fans.
