A presentation for civil engineers & others also, who have done training at HWPK RR site.

1. A
Presentation on
Practical training taken at
Heavy Water Plant, Kota
Submitted to: Submitted by:
Mr Sitesh Singh Lokesh Choudhary
Asst. Professor of Civil Dept. UID: K-10673

2.  Heavy Water Plant (Kota) is engaged in production of Heavy Water
whichisa strategicNuclearMaterial.
 Heavy Water is used as moderator as well as coolant in Natural
UraniumReactor .
 Heavy Water Production at HWP(K) is based on Hydrogen Sulfide Water
bi-thermalexchangeprocess.
 About 200 Tons of H2Sisused at HWP(Kota).

3. At the site, I have learnt the following seven different fields of civil engineering:
1. Water Treatment Plant
2. Tendering
3. Construction of pond
4. Strengthening of foundation
5. Road Resurfacing
6. Safety Measurements
7. Job Hazard Analysis

4. Construction of pond:

5. Pond Specification:
Area- 20’ * 10'
Height- Average 18cm.
Steps:-
 Site clearance
 PCC
 Random Rubble Masonry
 Coping
 Plaster

6. Site Clearance:
The site should be cleared of all obstructions such as:
• Woody vegetation, where the roots can cause severe cracking in pond
structures such as concrete water inlets and outlets.
• Tree stumps which, when decaying, can also weaken concrete pond
structures by leaving voids in the soil.
• Large stones, which may need to be dug out.
• Hills and animal burrows, which should be dug completely; clayey
soil should be tramped into the hole created.

7. Random Rubble Masonry:
The stones are not suitably shaped or finished and as such the elevation
of this type of stone masonry shows irregular shaped stones with non-
uniform joints. In a good work the face stones are of uniform colour and
approximately equal in size.

8. Coping
Coping consists of the capping or covering of a wall.

9. Water Treatment Plant:
Raw water
Intake
Screening
Chlorination Fire Purpose
Rapid Sand FilterClariflocculator
Store Drinking
Water
Charcoal Bed
Cation, Anion &
mix bed
Process feed
water

10. Road Resurfacing:-
The materials used for road resurfacing are:
1.) Aggregate- M25
• Cement- 43 grade
• Sand
• Aggregate
2.) Water

11. JHA
Job Hazard Analysis
A job hazard analysis is a technique that focuses on job tasks as a way to
identify hazards before they occur. It focuses on the relationship
between the worker, the task, the tools, and the work environment.
Ideally, after you identify uncontrolled hazards, you will take steps to
eliminate or reduce them to an acceptable risk level.

12. Tendering
• Normally tenders should be called for all works costing more than Rs.50,000. In
case where the work is to be awarded expeditiously, the prescribed period of
notice may be reduced. In urgent cases, or when the interest of the work so
demands, or where it is more expedient to do so, works may be awarded without
call of tenders after approval of the competent authority.
• The precise reasons should be recorded by the Divisional Officer before
dispensing with call of tenders for works costing more than Rs.50,000.
• The work awarded after calling for quotations shall be construed to have been
awarded without call of tenders.
• Normally, unless situation warrants otherwise, work orders shall be placed only
after competitive call of quotations with publicity through web and notice board.
• The period of notice for call of quotations may be decided by work order
accepting authority depending upon the urgency.
