2.0 PREREQUISITES None 3.0 PRECAUTIONS AND LIMITATIONS 3.1 Response to non-radiological process monitor alarms is the responsibility of the control room and is outside the scope of this procedure. Non-radiological monitors are listed in.
3.2 As used in this procedure, HIGH alanns are set to indicate that a Technical Specification or 10CFR20 limit is being exceeded, whereas an ALERT alann warns of an increased level which is approaching the HIGH alann setpoint. Unless otherwise specified, ALERT alarm response is considered the same as HIGH alarm response.
3.3 IF an ALERT/HIGH alann is validated, THEN IMMEDIATELY NOTIFY the Operations Superintendent(OS)/Control Room Supervisor (CRS).
3.4 Personnel evacuation announcements are made by Control Room personnel only, using the plant page system.
3.5 RMS alanns associated with daily operations such as door alanns, DLD sump pump runs, vent skid sampling, or monitor surveillance, are expected alanns and do not require response lAW with this procedure.
4.0 EQUIPMENT IMA TERIAL REQUIRED 4.1 Protective clothing 4.2 Survey instruments as required.

PROCEDURE 5.1 Radiation Monitoring System Alarm Determination NOTE Monitor icons on the RM-11 are color-coded. For the purposes of this procedure, yellow and red indications are ALERT and HIGH alarms, respectively. Other monitor indications (white, magenta, dark blue, or light blue, are referred to as FAIL alarms 5.1.1 Upon receipt of an RMS alarm, RECORD the alarm information in the Shift Radiation Protection Technician (SRPT) log..
5.1.2 CONTACT the Main Control Room AND REPORT the alarm. NOTIFY the OS/CRS of any ALERTIHIGH alarm, AND DISCUSS potential actions AND CONSIDER recommendations at this time.
5.1.3 IF the indication is a FAIL alarm (e.g., loss of process flow, loss ofRM-23 communications), THEN PROCEED to Section 5A.
5.lA IF the indication is an ALERT/HIGH alarm, THEN PROCEED to Section 5.2.
5.2 ALERT/HIGH Alarm Validation 5.2.1 ATTEMPT to determine the cause of the alarm as soon as possible. Possible causes include, but are not limited to:
A.
Operation of the Mechanical Vacuum Pump with known or suspected failed fuel.
IF validated, THEN GO to S.3.l.A AND REFERENCE HC.RP-ST.ZZ-0004(Q), Gaseous Effluent Surveillance, for additional RP response. OTHERWISE, CONTINUE.
B.
Surveillance/maintenance on the affected monitor without notifying RP.

CONT ACT the work party to verify the alarm is the direct result of maintenance or surveillance activities.
Hope Creek Page 3 of61 Rev. 17
HC.RP-AR.SP-OOOI (Q)
C.
Check source mechanism malfunction (check source has jammed or is sticking).
VERIFY that the check source initiation time corresponds to the monitor alarm time.
RE-RUN the source check. A satisfactory check source test should clear the alarm.
D.
Electronic noise. Welding or operation of high-frequency equipment in the vicinity of a monitor can create spiking alarms (alarms that indicate, then immediately clear).
SELECT the RM-ll icon AND NOTE whether the alarm clears.
CONTACT the work party AND VERIFY the alarm time corresponds with their work activities.
IF electronic noise caused the alarm, THEN REQUEST the work party to reconfigure their equipment setup (e.g., ground cable position).
E.
A previously documented malfunction of monitor equipment.
CHECK for a notification or work order that has previously identified the monitor malfunction with alarm characteristics that specifically match the current alarm.
5.2.2 IF the cause of the alarm is determined and the alarm is believed to be invalid, THEN CONTACT the OSIeRS AND REPORT the basis for that detennination.
5.2.3 IF the OS/CRS concurs that the alarm is invalid, THEN PROCEED to Section 5.5.
5.2.4 IF the alarm cannot be proven invalid, THEN PROCEED to Section 5.3.
5.3 ALERT/HIGH Alarm Response Hope Creek 5.3.1 IF the cause of an ALERTIHIGH alarm can not be determined, THEN CONSIDER the alarm valid AND RESPOND as follows:
A.
IF the ALERT/HIGH alarm is from a duct/gaseous effluent monitor, THEN RESPOND lAW Attachment 2.
B.
IF the ALERT/HIGH alann is from an area radiation monitor, THEN RESPOND lAW Attachment 3.

ATTACHMENT 2 Page 1 of28 DUCT/GASEOUS EFFLUENT MONITOR ALARM RESPONSE This attachment provides guidance for response to ALERT/HIGH alarms on duct and/or gaseous effluent monitors.
Actions may be performed in any order and are not limited to the information in this attachment.
Where applicable, periodically UPDATE the OS/CRS and Duty NTS-RP throughout the alarm response process.
CAUTION The associated gaseous effluent monitors on the NPV, SPV, and FRVS skids may not indicate an increase depending on the type and duration of the release. Consider obtaining samples from the applicable vent skid to assist in validating the alarm
- 1.
IF an ALERT / HIGH alarm is received on a gaseous effluent monitor, THEN:
IF the monitor is a Tech Spec andlor ODCM monitor per this Attachment, THEN INITIATE a Station Status Checklist using NC.EP-EP.ZZ-0309(Q), Dose Assessment (MIDAS) Instructions.
OBT AIN samples from the skid as required.
FIELD COUNT samples to evaluate the severity of the radiological conditions prior to analysis.
- 2.
IF physically possible, THEN SURVEY potential plant exhaust points for increased contamination and radiation levels.
- 3.
IF contamination is found outside the plant exhaust points, THEN ASSIST the OS/CRS in implementation of Attachment 13 of the Event Classification Guide (ECG). REFER to the
'Onsite Contamination Checklist'.
- 4.
CHECK adjacent or corroborating monitors. Corroborating monitors are listed in the 'Monitor Information' section of this attachment.
An alarm on a corroborating channel may be a direct indication of increased activity within the duct I exhaust pathway.

ATTACHMENT 3 Page 1 of 16 AREA RADIATION MONITOR (ARM) ALARM RESPONSE This attachment provides guidance for response to ALERT/HIGH Area Radiation Monitor (ARM) alarms Actions may be performed in any order and are not limited to the information in this attachment.
Where applicable, periodically UPDATE the OSICRS and Duty RP Supervisor throughout the alarm response process.
- 1.
CHECK adjacent or corroborating monitors. Corroborating monitors are listed in the 'Monitor Information' section of this attachment.
An alarm on a corroborating channel may be a direct indication of increased radiation levels in the affected areas of the plant.
- 2.
PERFORM any necessary radiological surveys AND CONSIDER:
Changes in plant conditions or work evolutions may change the radiological conditions in the vicinity of the ARM.
Transportation or storage of radioactive materials near the detector may cause monitor alarms.
- 3.
IF survey results indicate a radiological problem in the area, THEN PERFORM, as a minimum, the following:
SECURE any work in progress in the affected area, AND INSTRUCT personnel to leave the affected area, as needed. INFORM personnel of the radiological conditions AND PROVIDE any necessary assistance in contaminated areas.
FOLLOW normal access control procedures unless a severe radiological hazard exists (e.g., radiological levels that may result in exceeding personnel administrative dose limits).
CONTROL area access until confirmation surveys and any required reposting are complete.
CONSIDER using 'NO ENTRY' or 'KEEP OUT' supplemental information on initial postings.
- 4.
PERFORM applicable follow-up actions lAW Section 5.5.

ATT ACHMENT 4 Page 1 of7 LIQUID PROCESS MONITOR ALARM RESPONSE This attachment provides guidance for response to liquid process monitor alarms.
Actions may be performed in any order and are not limited to the information in this attachment.
Where applicable, periodically UPDATE the OS/CRS and Duty RP Supervisor throughout the alarm response process.
- 1.
CHECK adjacent or corroborating monitors. Corroborating monitors are listed in the 'Monitor Information' section of this attachment.
An alarm on a corroborating channel may be a direct indication of increased activity within the liquid process pathway.
- 2.
IF the alarm occurs on the Liquid Radwaste or Cooling Tower Blowdown radiation monitors, THEN ENSURE the discharge has automatically isolated.
REFER to HC.RP-ST.SP-0007(Q), Liquid Effluent Surveillance, for actions taken after an automatic isolation.
- 3.
PERFORM any necessary radiological surveys AND CONSIDER:
Changes in plant conditions or work evolutions may change the radiological conditions in the vicinity of the detector.
Transportation or storage of radioactive materials near the detector may cause monitor alarms.
- 4.
IF survey results indicate a radiological problem in the area, THEN PERFORM, as a minimum, the following:
SECURE any work in progress in the affected area, AND INSTRUCT personnel to leave the affected area, as needed. INFORM personnel of the radiological conditions AND PROVIDE any necessary assistance in contaminated areas.
- 5.
PERFORM applicable follow-up actions lAW Section 5.5.
